[0:15] * kcj (~kcj@unaffiliated/kcj) has joined #raspberrypi
[0:15] <Cheekio> Just asking for a speedy allow/deny on my first post, I've been dealing with this issue for days and I only have like 18 hours a week of free time.
[0:15] <Cheekio> Starting, like, 12 hours ago.
[0:16] <ShorTie> what is your problem ??
[0:16] <Cheekio> omxplayer dies after about 20 minutes
[0:16] <Cheekio> It's pretty consistently 20 minutes. Across RPI2's, video files, tvs, and distros
[0:16] <Cheekio> And it's not an undervoltage issue
[0:17] <Cheekio> Right now I'm debugging on raspbian but if was evident on kodi
[0:17] <ShorTie> the best way to search the forums is with google with site:raspberrypi.org

[0:18] <ShorTie> nothing in any of the logs ??
[0:19] <Cheekio> Not in kern.log, syslog, dmesg, or omxplayer's -g log
[0:19] <ShorTie> in /var/logs
[0:19] <Cheekio> Yeah
[0:19] <Cheekio> Xorg.0.log had...
[0:20] <ShorTie> this is with wifi ??
[0:20] <Cheekio> FBIOBLANK: Operation not permitted
[0:20] <Cheekio> But then I went and turned off blankscreen via xset
[0:20] <Cheekio> and the energysaver settings

[0:21] * hagbard_ (~hagbard@2a03:4000:2:2fb::1) has left #raspberrypi
[0:21] <Cheekio> and the BLANK_TIME values in /etc/kbd/config as well as the power down time
[0:21] <Cheekio> It is wifi
[0:21] * plugwash (~plugwash@97e3d836.skybroadband.com) has joined #raspberrypi
[0:21] <Cheekio> I think I downloaded something to the sd card and recreated it, but I need to retry to confirm
[0:22] <Cheekio> omxplayer's output gave "Did not recieve a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.have a nice day ;)
[0:24] <ShorTie> maybe try googling 'debian disable screen blank', i see some answers, but i'd just be repeating them, so....
[0:24] <Cheekio> Yeah, I disabled it for console and for xserver
[0:25] <Cheekio> And I tested it against forcing the screen blank and powersave settings, couldn't cause omxplayer to crash
[0:25] <ShorTie> with 'FBIOBLANK: Operation not permitted' it does seem like a blanking problem
[0:25] * utack (~utack@mnch-5d87ab71.pool.mediaWays.net) has joined #raspberrypi
[0:25] <Cheekio> you can 'xset s activate' to blank the screen

[0:48] <Cheekio> Woo! My post is on the rpi forums
[0:49] <Cheekio> I stopped and restarted Archer about 5 minutes into the show, and it didn't crash at all through the end
[0:49] <Cheekio> I may have the solution to this problem
[0:49] <Cheekio> http://www.raspberrypi.org/forums/viewtopic.php?f=28&t=104055
[0:49] <Cheekio> If I solved it, it's pretty much the lamest solution.
[0:50] <Cheekio> It's like, you'd read through all the debug steps and say, 'man, he knows what he's doing' and then you'd see the reply where I solved my own problem and be like 'man, what a moron'

[1:19] <plugwash> be_, because standard qemu builds don't emulate a pi
[1:19] <be_> ah
[1:20] <plugwash> they can emulate a system that has the same CPU and the same amount of memory as the pi but the similarities between the emulated system and the pi pretty much end there so a different kernel is needed
[1:20] <be_> what else needs to be the same?
[1:20] <plugwash> IIRC someone did try to make a version of qemu with a pi emulation mode, I don't recall how far they got
[1:21] <plugwash> arm systems are not like PCs
[1:22] <be_> I don't know much about emulation, but I'd think that the CPU, memory, and a way to access the storage of a host would be the minimum necessary
[1:22] <plugwash> on PCs there is a stanard platform. Devices are either found at standard addresses or placed on enumeratable busses with the enumeration registers for the root PCI bus in a standard location
[1:23] <McBride36> maybe i'm dumb, but is it emulating an ARM system? or just a computer that has the same specs as the pi?
[1:23] <plugwash> On arm systems every SoC vendor choses a different selection of hardware and puts it at different addresses on a non-enumeratable busses
[1:24] <be_> oh, so do ARM kernels have to have the addresses of every piece of hardware compiled into them?
[1:25] <plugwash> In most cases yes, when compiling a kernel you specify a "platform" which tells the kernel what the core devices are and where to find them
[1:25] <stevenjames> is there an irc channel where i can just talk shit to random people?
[1:26] <be_> stevenjames: I'm sure there are on other networks. I'm not sure about Freenode...
[1:26] <plugwash> There has been some work on supporting multiple platforms in the same kernel but it's still relatively new stuff
[1:26] <be_> plugwash: okay. that makes sense why QEMU would have to be modified to exactly emulate the Pi
[1:27] <McBride36> stevenjames, what do you mean? just like talk about random stuff?
[1:27] <stevenjames> i tried troll and talkshit and everything. i love learning about my pi and linux and networks, but sometimes i just want to talk shit to random people hahahaha
[1:28] <McBride36> it's for an online webgame but you're welcome to do that within reason at a channel i am in, #tagpro
[1:28] <McBride36> having said that, i just realized online and webgame is redunant
[1:29] <be_> plugwash: so is that also why there are different builds of CyanogenMod for every Android device it supports?
[1:29] <plugwash> yeah
[1:29] * Macuser (~textual@unaffiliated/macuser) has joined #raspberrypi
[1:29] <stevenjames> hahahaha that's funny, sometimes i just want to go in on random people who will talk crazy back. i didn't know i there was a channel for that STRICTLY
[1:29] <be_> thanks for explaining. The universe makes sense again.

[3:30] <queuetue> Hello, first time raspi user, (pi2, model b, raspbian 7) I'm trying to use hcitool to list bluetooth devices, and nothing is showing even though I have my iphone showing "device is discoverable". lsusb shows my dongle, and hcitool dev shows a MAC. Where do I go from there to troubleshoot this?
[3:31] <queuetue> lsusb shows Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI Mode)
[3:33] <queuetue> hcitool lescan returns "Set scan parameters failed: Input/Output error"
[3:34] <methuzla> what about just hcitool scan
[3:35] <queuetue> methuzla: It scans, but returns nothing.
[3:36] <methuzla> check bluetooth service is running: sudo service bluetooth status
[3:36] <queuetue> Not running - should I start it?
[3:37] <methuzla> i think so
[3:38] <queuetue> hcitool can still comes back with nothing, unfortunately, but the service shows as running now.
[3:38] <queuetue> (can/scan)
[3:38] <methuzla> not sure then, maybe need to do something on iphone?
[3:39] * chipmadness (~chipmadne@75-134-183-81.dhcp.bycy.mi.charter.com) has joined #raspberrypi
[3:39] <queuetue> I've got a number of BT services running nearby - speakers, keyboard, computer, iphone - one of them should be showing, I would think. I think it's a pi problem.
[3:42] * hyperair (~hyperair@ubuntu/member/hyperair) Quit (Ping timeout: 244 seconds)
[3:42] <methuzla> don't those have some kind of pairing button that must be pressed?
[3:43] <queuetue> The keyboard, I keep refreshing, the computer and the phone are both showing "discoverable" and the speakers are just opportunistic.
[3:44] <queuetue> So you think the pi is working, it's an external problem?
[3:45] <McBride36> so nothing is showing up?
[3:46] <queuetue> Nothing is showing in scan, no.
[3:46] * chipmadness (~chipmadne@75-134-183-81.dhcp.bycy.mi.charter.com) Quit (Quit: Leaving)
[3:47] <queuetue> Interestingly enough, the computer can see the pi.
[3:48] <McBride36> via bluetooth?
[3:48] <queuetue> McBride36: Yes.
[3:50] <queuetue> Not good - when I try to connect to it from the computer, wlan0 went down.
[3:50] <queuetue> (In bluetooth manager on mac)
[3:52] <methuzla> what did you mean by "The keyboard, I keep refreshing"?
[3:52] * hyperair (~hyperair@ubuntu/member/hyperair) has joined #raspberrypi
[3:53] <queuetue> There's a button on it that tells it to be available for pairing, I keep pushing it so it's ready to pair before doing a scan.
[3:54] <methuzla> i'd expect that to show something on the pi

[9:42] <jasabella> hi :)
[9:42] <shiftplusone> hi
[9:43] <jasabella> in theory, you could both power your raspberrypi via usb and talk to it via a twisted pair ethernet cable from the same computer right?
[9:44] <shiftplusone> If I understood you right, yes.
[9:44] * nils_2 (~nils_2@unaffiliated/nils-2/x-2480262) has joined #raspberrypi
[9:44] <Kunsi> if you usb port can supply enough power, yes

[9:44] * splix (~splix@ has joined #raspberrypi
[9:44] <jasabella> hmmm... why is that?
[9:45] <shiftplusone> because at higher loads, some usb ports won't be able to put out enough current.
[9:45] <jasabella> i understand that 1.2-2A is preferred
[9:45] <jasabella> yep
[9:45] <shiftplusone> or rather put out enough voltage, I should say.
[9:45] <jasabella> 5V hmmm
[9:46] <jasabella> what about usb ports designed to charge devices? the always on ones
[9:46] <shiftplusone> depends on the implementation.

[9:46] * leichtgewicht (~leichtgew@pw126205012193.3.panda-world.ne.jp) Quit (Remote host closed the connection)
[9:46] <jasabella> i suppose i'll have to read specs
[9:47] <shiftplusone> devices which get charged don't care too much about the voltage, so chargers can get away with putting out something like 4.5v... the pi wouldn't like that.
[9:48] <jasabella> wow that's like 10% less than the nominal voltage, it's that bad?
[9:49] <ShorTie> they are only charging like a 3.7v cell so....

[11:52] <paowz_> I'm new to raspberry world and just got a rpi 2.. I retrieved Snappy img to test it out.. and have some questions..
[11:52] <MY123> paowz_, use true #ubuntu
[11:52] <MY123> see @wintrmute on the RPF forums
[11:52] <paowz_> sorry ?
[11:55] <MY123> paowz_, http://www.raspberrypi.org/forums/viewtopic.php?f=56&t=98997
[11:55] <paowz_> I'm glancing at first partition, showing dtb and many config files.. leaving me thinking the following tuto http://www.raspberrypi.org/documentation/linux/kernel/building.md not sufficient at all..
[11:55] <paowz_> MY123, ok, I see thanks.
[11:55] <MY123> paowz_, don't use Snappy if you want something useful, at least for #now
[11:55] <ShorTie> he is talking about the forums @ http://www.raspberrypi.org/forums/
[11:56] <paowz_> MY123, why not Snappy ? This is the img provided on RPI website..
[11:56] <MY123> paowz_, too few packages
[11:56] <MY123> paowz_, and not even a GUI
[11:57] <ShorTie> snappy is @ 'alpha-02', so it hasn't even made it to a beta version yet
[11:57] <MY123> no Clang, no GCC, no...
[11:57] <paowz_> ok, thanks MY123..
[11:57] * Tachyon` is now known as Tach[Away]
[11:58] <paowz_> ..and do you believe TTL console still available ? http://elinux.org/File:Adafruit-connection.jpg
[11:58] * ShorTie don't understand why they would put 'alpha' versions on the download page anyways
[11:58] <MY123> paowz_, depends, not by default as I know
[11:58] <MY123> (HATs)
[11:59] <paowz_> MY123, how do you reach your device, once flashed ?? SSH ?
[12:00] <MY123> paowz_, HDMI+USB or SSH on IPv4/IPv6 on Ethernet

[12:13] <heller\> hello
[12:13] <shiftplusone> paowz_, you'll need to copy the arch/arm/boot/dts/*dtb files into the correct places on boot after compiling and also pass the kernel through mkknlimg
[12:13] <heller\> is there a reason why all tutorials say that dht22 and ds18b20 goes to GPIO4?
[12:14] <shiftplusone> going to guess those are 1 wire devices and 1 wire is on gpio4 by default?
[12:14] <heller\> but i can change it can i?
[12:15] <shiftplusone> yeah, I believe it's a dt parameter.
[12:15] <heller\> but just wondering why on default, they are on the same pin
[12:15] <heller\> lots of users have dht22 and ds18b20 on same raspberry
[12:15] <heller\> isnt it frustrating to keep on them on same pin by default :)
[12:15] <paowz_> hi shiftplusone ! Thanks for the tip. Do you have any link referring to documentation regarding this ?
[12:16] <shiftplusone> paowz_, nope, it's a new thing, but feel free to ask if something's unclear.
[12:16] * hyperair (~hyperair@ubuntu/member/hyperair) has joined #raspberrypi
[12:17] <shiftplusone> heller\, I don't know if the pi will do 1 wire devices on different pins. AFAIK, it's bit-banged, but I don't know if it supports multiple devices...
[12:17] <shiftplusone> but yeah, I don't know... haven't used w1 on the pi.

[12:19] <paowz_> thanks.
[12:19] <shiftplusone> so you'd run something like ./mkknlimg arch/arm/boot/zImage /media/piboot/kernel7.img, for example.
[12:19] * goretoxo (~yaaic@ has joined #raspberrypi
[12:19] <heller\> but i can use for example GPIO14 which is UART_TXD for dht22?
[12:20] * hagbard_ (~hagbard@2a03:4000:2:2fb::1) has joined #raspberrypi
[12:20] <shiftplusone> don't know
[12:20] <paowz_> shiftplusone, I saw kernel7.img on snappy first partition.. why this suffix ?? why 7 ?
[12:20] <MY123> paowz_, ARMv7
[12:20] <paowz_> ok..
[12:21] <shiftplusone> paowz_, pi 2 loads kernel7.img, pi1 loads kernel.img
[12:21] <shiftplusone> but pi 2 will fallback to kernel.img as well.
[12:21] <ShorTie> that makes sense, i was wondering too....
[12:21] <shiftplusone> and of course there's config.txt, which can override those setting if you need to.
[12:21] * Alina-malina (~Alina-mal@unaffiliated/alina-malina) has joined #raspberrypi
[12:22] <MY123> ShorTie, it is also worth noting that RISC OS has one image compatible with Pi1 and Pi2 at the same time
[12:22] <paowz_> does mkknlimg take care of initrd like mkbootimg would do on Radxa platform (for those who know..)
[12:22] <ShorTie> really, interesting
[12:23] * cameronfr (~cameronfr@ Quit (Quit: My Mac has gone to sleep. ZZZzzz…)
[12:23] <shiftplusone> paowz_, not sure what you mean by 'take care of initrd'
[12:24] <shiftplusone> afaik, it just adds a trailer to the kernel to make it work with device tree. Works if there's an initramfs baked in or not.
[12:24] <hagbard_> Does anyone know how userland dma works for the Pi2 ? I try getting pifm to work, but i don't know where to start with changing the dma stuff.
[12:24] <hagbard_> Or does someone have an old version of pifm without dma?
[12:25] <paowz_> I assume kernel won't do anything if it doesn't come with an initrd img.. I might be wrong, reading your lines..
[12:25] <shiftplusone> paowz_, it will work just fine without initrd.
[12:25] <MY123> paowz_, it can load the rootfs directly
[12:25] <MY123> (if the drivers are embedded)
[12:25] <shiftplusone> hagbard_, I think the manual is pretty clear about DMA. got a specific question?

[12:26] * ZacharyIgielman (~ZacharyIg@ has joined #raspberrypi
[12:26] <hagbard_> Wasn't aware that there's a manual where dma is described.

[12:27] <hagbard_> I'll have a look at it, thx.
[12:27] <shiftplusone> paowz_, aside from debootstrap for debian-based systems, I use buildroot for minimal things.
[12:27] * Strykar (~wakka@ has joined #raspberrypi

[12:31] <hagbard_> shiftplusone: All i could find by searching for that was for the Pi1. In Pi2 dma seems to work different than in pi1.
[12:32] <shiftplusone> hagbard_, you'd use a different base address, that's all.
[12:32] <shiftplusone> the offsets are the same
[12:33] <hagbard_> Yes, i tried that for some gpio-stuff and it worked. But dma seems to be quite a different horse.

[12:36] <hagbard_> From what i read i'd need to allocate memory by a mailbox interface do some juggling with the chaches and the flushing thereof, but i couldn't find anything specific.
[12:38] <shiftplusone> That's the easy way to get a hardware address (which DMA requires), yes.

[12:41] * cameronfr (~cameronfr@ has joined #raspberrypi

[14:13] <shiftplusone> ah okay, I was running the backend and frontend on the same pc, iirc.
[14:13] <ali1234> the front end is pretty horrible, but i don't use it at all
[14:14] <ali1234> all the backend has to do is copy the transport stream, which is 28mbps iirc, over USB 4 times
[14:14] <ali1234> tuner -> ringbuffer, ringbuffer -> ethernet
[14:15] <shiftplusone> If you can find a tuner which doesn't throw a spanner in the usb stack
[14:15] <ali1234> my tuner uses 250mA though, and i have no idea how much a USB hard drive will use
[14:15] <ali1234> hmm what do you mean by that? my tuner works fine on my current set up
[14:16] <shiftplusone> which one is it?
[14:16] <ali1234> er... it's the DVB-T2 one, the only one supported on linux...
[14:16] <ali1234> pctv 530e?
[14:16] <shiftplusone> they seem to generate a lot of requests/sec, which trips things up. Maybe the situation has improved on the pi2 or you got lucky with the dvb stick. I haven't even tried since I thought it's unlikely to work.
[14:17] <ali1234> well i use it on a PC at the moment but it burns too much electricity
[14:17] <shiftplusone> oh, so have you tried it in the pi or not?
[14:17] <ali1234> nope
[14:17] <shiftplusone> *on
[14:17] <shiftplusone> ah... well, that's something to look into.
[14:17] <ali1234> i guess i could test it on my A+
[14:18] <ali1234> i don't see why it wouldn't work though, unless the USB stack is completely pants

[14:24] <shiftplusone> The pi is probably the only device where I've never had the connector break, but that's probably only because I rarely unplug it.
[14:25] <shiftplusone> but usb hdd enclosures barely last a few weeks, it seems.
[14:25] <ali1234> yeah i've had loads of those die, but usually it is the power supply that goes

[14:30] <uuhimhere> shiftplusone, so what do you think of plopping the pi2 compute module into the upcoming dragonbox pyra ?
[14:30] <ali1234> buying class 10 sd cards is pointless right? cos it's only the linear write speed
[14:31] <shiftplusone> ali1234, that is the conventional wisdom, yes. Haven't done any tests myself, but that's what the people who have say.
[14:31] <uuhimhere> would alot of functionality be lost if someone shoved a pi2 compute module into thisboards.openpandora.org/topic/16746-populated-mainboards/?p=348715
[14:31] <shiftplusone> uuhimhere, I don't understand what the point would be. By the time you get the electronics in there to power the compute module, interface the electronics and all that, you'll run out of room and not gain anything over the pyra.

[14:33] <ali1234> i would like to see a nice motherboard with a compute module slot on it. not the CMIO.
[14:33] <uuhimhere> i just think it would be cool to have a production quality portable netbook/console running on a pi2
[14:33] <shiftplusone> well there's openpi https://www.kickstarter.com/projects/wirelessthings/openpi-wireless-computer-for-inventors-makers-and
[14:33] <shiftplusone> unless you mean motherboard as in... atx.
[14:34] <ali1234> no, not ATX
[14:34] <uuhimhere> the openpi's not aportable
[14:34] <ali1234> just more motherboard-y than the CMIO
[14:34] <ali1234> designed to be a computer, not a breakout board
[14:34] <shiftplusone> I'm looking forward to getting my Slice and the compute module 2 upgrade... whenever that happens.
[14:35] <shiftplusone> ali1234, why would you want something like that instead of a normal pi though?
[14:35] <uuhimhere> shiftplusone, would be nice if someone comes up with a crowdsource project for a proper netbook adaptation to the pi2
[14:35] <ali1234> because the normal pi has a lot of annoying compromises
[14:36] <shiftplusone> uuhimhere, seen the pi-top?
[14:36] <uuhimhere> shiftplusone, thats a hack
[14:36] <uuhimhere> shiftplusone, brick-top
[14:36] <uuhimhere> shiftplusone, looks like it was made outta ducktape
[14:37] <ali1234> i quite like the look of the pi-top
[14:37] <ali1234> it's utilitarian

[14:38] <ali1234> well 3d printing isn't cheap
[14:39] <uuhimhere> ali1234, hey at least it looks cheap
[14:39] <ali1234> $500 for a laptop with 100% commodity parts *is* cheap

[14:42] <uuhimhere> thats too big

[14:42] <ali1234> you want the moon on a stick

[14:43] <uuhimhere> i can only assume they borrowed the notion of their pluggable from rbpi foundation
[14:43] <shiftplusone> uuhimhere, pitch the idea to evildragon.... who knows...
[14:44] <uuhimhere> well what if they get all apprehensive and defensive because its not a module that they developed ?
[14:44] <uuhimhere> it is after all a *downgrade*
[14:44] <ali1234> why don;t you just get their module?
[14:45] <uuhimhere> well that depends on how much the module costs
[14:45] <uuhimhere> if they sell the pyra alone minus the module and it comes to less than 300bucks i think the pi module is worthwile
[14:45] <shiftplusone> Oh, I'm an idiot... I didn't notice they have a carrier board separate from the brain on the pyra.
[14:46] <uuhimhere> shiftplusone, yes they plan on having amd modules, ti modules, exynos etc etc
[14:46] <ali1234> pointless
[14:46] <shiftplusone> I think if they do a CM2 version, they'd sell quite a few.
[14:46] <ali1234> yes, that would sell
[14:46] <shiftplusone> hell, I'd buy one.
[14:47] <ali1234> nobody is going to buy *random ARM chip number 3243276*
[14:47] * Dickie (~Dickie@unaffiliated/dickie) has joined #raspberrypi
[14:47] <ali1234> it's bad enough portin everything once
[14:47] <ali1234> pluggable modules just increases the fragmentation
[14:47] <MY123> ali1234, there is a lot who would buy a bare Cortex-a7
[14:47] <uuhimhere> ali1234, pointless ?
[14:47] <ali1234> they should just adapt it to the CM and not bother making their own CPU module
[14:48] <MY123> ali1234, if it has PCIe
[14:48] <Dickie> I'm looking for a case which will enclose the microsd card. Does anyone know of one?
[14:48] <ali1234> they'd sell infinitely more that way
[14:48] <uuhimhere> shiftplusone, maybe you could approach evil dragon?
[14:48] <shiftplusone> Dickie, enclose entirely or just force you to use your nail to click it out?
[14:49] <Dickie> Entirely would be preferable
[14:49] <Dickie> But difficult will suffice
[14:49] <Dickie> I'm making retro consoles for family members
[14:49] <Dickie> Don't want them mucking it up
[14:49] <uuhimhere> ali1234, yeah maybe you should give them that bright idea

[14:50] * noarchy (~noarchy@198-48-206-43.cpe.pppoe.ca) has joined #raspberrypi
[14:51] <ali1234> anyway i'd rather have a pi-top
[14:51] <Dickie> Oh, B+, btw
[14:51] <ali1234> but i'd remove the touchpad and make the keyboard bigger. or the screen smaller.
[14:51] <uuhimhere> ali1234, but its such a bright idea... tell a bunch of guys who have achieved what very few communities out there have achieved out of their own time money and effort, how they should align with the rbpi foundation... because it would benefit them somehow?
[14:53] <uuhimhere> for some reason theyd probably just be like hey its all open plug it in and see what happens guys
[14:53] <shiftplusone> hmm... I wonder how many lapdocks were sold simply because they are pi compatible
[14:53] <ali1234> probably more than got sold for the atrix, because absolutely nobody bought them
[14:53] <uuhimhere> lapdocks are pi compatible?
[14:53] <ali1234> they are just HDMI and USB so yeah
[14:53] <shiftplusone> uuhimhere, the new ones seem to be a little trickier to get to work, but yeah.
[14:54] <uuhimhere> yeah but lapdocks are big corporate products that didnt target a compute-module like platform to begin with...
[14:55] <ali1234> the atrix was kind of a compute-module type device
[14:55] <ali1234> just wrapped up in a mobile phone
[14:55] <ali1234> it was supposed to be "convergence"
[14:55] <uuhimhere> the pandora could actually sell(as you mentioned) with a pi2 compute-module seeing as the stock one would make the system run upwards to 500Euro

[14:55] * Ryccardo (~riki@adsl-ull-83-74.42-151.net24.it) Quit (Ping timeout: 264 seconds)
[14:55] <uuhimhere> actually 500 euro's the conservative estimate
[14:55] <ali1234> but it failed hard because nobody wants to plug their phone in to their TV or in to their laptop to make it work, and then fiddle around to unplug it when they get a call
[14:56] <uuhimhere> shiftplusone, i wonder where the bulk of the cost lie? percentage wise for the pyra 70:30% pyra:omap compute module?
[14:57] <ali1234> probably closer to 90:10
[14:57] <ali1234> getting cases made is not cheap
[14:57] <shiftplusone> I think the non-tangible stuff like logistics/manufacturing/markup is the bulk of it
[14:58] <ali1234> yeah
[14:58] <uuhimhere> though having said that a pi-yra migh actually catch broadcom's eye and who knows after that....

[14:59] <uuhimhere> how come
[14:59] <ali1234> broadcom wouldn't even get out of bed for the number of sales the pandora had
[14:59] <uuhimhere> yeah but a pi-netbook for every pi owner out there?
[15:00] <uuhimhere> whats the count right now
[15:00] <uuhimhere> 15 million and counting?
[15:00] <shiftplusone> nowhere near
[15:00] <ali1234> hate to break it to you, but that's tiny
[15:01] <uuhimhere> shiftplusone, really all pi iterations <15mil?
[15:01] <shiftplusone> 5 million
[15:01] <MY123> shiftplusone, Broadcom have a good CPU, just a good GPU is the part missing
[15:01] <ali1234> global smartphone sales are set to hit 1 billion units annually this year

[15:01] * hyperair (~hyperair@ubuntu/member/hyperair) Quit (Ping timeout: 245 seconds)

[15:02] <MY123> SpeedEvil: no. NASDAQ:BRCM made high speed interfaces
[15:02] <MY123> (like MIPI DSI/CSI)
[15:02] <ali1234> also i would be willing to bet that nearly every pi owner regularly uses at least one other device with a broadcom CPU in it, and doesn't even know

[15:03] <SpeedEvil> That's pretty much meaningless.
[15:03] <ttys0> It's great for a learning system, and a proof of concept test bed, which is what I tend to use mine for. Perhaps folks disappointed with the performance have an expectation that's disconnected from the intention of the product.

[15:04] <MY123> uuhimhere, you have a bare AXI bus
[15:04] <ali1234> the performance is fine. the education value is suspect however, given how little we know about the hardware even now

[15:09] <MY123> uuhimhere, or the 256-core Atmel AVR system
[15:09] <MY123> uuhimhere, it's a little useless
[15:09] * Dickie (~Dickie@unaffiliated/dickie) has left #raspberrypi
[15:10] <uuhimhere> so we'll never see a pi with any of the SoC's from BRCM's mobile-handheld adventure?
[15:10] <uuhimhere> ie bcm 21553,21664,28155 etc etc
[15:10] <MY123> uuhimhere, Broadcom may prepare a new SoC
[15:10] * ukgamer|away is now known as ukgamer
[15:11] <SpeedEvil> It seems very unlikely a Pi3 will arrive immediately after the PI2
[15:11] <MY123> uuhimhere, Vulkan will probably be supported in a newer chip, which means a complete redesign of a 3D subsystem
[15:11] <shiftplusone> uuhimhere, computability is important for the foundation's goals. A lot of the work that went into the pi won't just work in other chips, even the VC ones.
[15:11] <SpeedEvil> Epecially given the comments that the PI2 had enginnering import
[15:11] <SpeedEvil> Compatibility to the platform absolutely should not be a goal - regrettably
[15:11] <MY123> SpeedEvil, there is architectural problems for newer APIs
[15:11] <uuhimhere> they could just release newer modules
[15:12] <SpeedEvil> ^had enginering input into the SoC
[15:12] <uuhimhere> shiftplusone, well wasnt the issue lack of ARMv7?
[15:12] <MY123> shiftplusone, you will have to break this one day
[15:12] <MY123> shiftplusone, why is not the chip 28nm?
[15:14] <shiftplusone> uuhimhere, take an early pi1 with the first image that was released to appreciate how far the software has come. Moving to an entirely new chip would set things back, make a lot of resources invalid and require a lot of engineering time to bring to a decent state.

[15:19] <MY123> shiftplusone, it is weak
[15:19] * yeticry (~yeticry@ has joined #raspberrypi
[15:20] <MY123> uuhimhere, the one on the Odroid-C1 has twice the 3D performance

[15:20] <shiftplusone> aside from the things anholt is addressing
[15:20] <MY123> shiftplusone, running Compiz at 1080p when using mplayer
[15:21] <MY123> ali1234, OpenGL 2.1
[15:21] <MY123> shiftplusone, VLC is even more slower
[15:21] <ali1234> can it at least do ES 2.0?
[15:21] * nimoot (~HomoSapie@unaffiliated/toomin) has joined #raspberrypi
[15:21] <MY123> ali1234, yes
[15:21] <ali1234> that's something then
[15:22] <uuhimhere> MY123, how do you gauge that?
[15:22] * ndrei (~avo@ has joined #raspberrypi
[15:22] <uuhimhere> MY123, when i run antutu on my "crappy" BCM21664 based android phone the GPU "ranks" among the 10th upper percentile
[15:22] <uuhimhere> for 3d
[15:22] <MY123> uuhimhere, there is a big res difference between the phone and a 1080p screen
[15:22] <shiftplusone> bah, no work done at all today. =/
[15:23] <uuhimhere> i cant tell the difference between 1080 and 480 on a smartphone LCD
[15:23] <shiftplusone> AND there's no milk in the fridge >=/. Everything is terrible >.>
[15:23] <uuhimhere> nor would i bet any normal human would
[15:23] <uuhimhere> shiftplusone, coffee?
[15:23] <MY123> shiftplusone, use the www
[15:24] <shiftplusone> hm?
[15:24] <MY123> shiftplusone, or go to Sainsbury's or another big store
[15:24] <uuhimhere> 1080p's for 64 inch screen with a viewing distance of at least 12 feet
[15:24] <shiftplusone> but that's like a 15 minute walk D=
[15:25] <uuhimhere> unless of course you want the pi to display on a big big screen
[15:25] <uuhimhere> all i want is a pi-pyra
[15:25] <uuhimhere> i even have a name for it
[15:25] <uuhimhere> sounds like papyrus
[15:25] <uuhimhere> pi-pyra
[15:26] <shiftplusone> well, go hassle #openpandora =P
[15:26] <uuhimhere> and the software library of open pandora zzomg
[15:26] <uuhimhere> shiftplusone, well theyre happy with pyra
[15:27] <MY123> uuhimhere, /print "no Pandora's here. please go elsewhere"
[15:27] <uuhimhere> i hear theyre having an awful time with the new powervr though
[15:27] <MY123> uuhimhere, true
[15:27] <MY123> like always with imagination
[15:28] <uuhimhere> that would be a good cause to use a vc4 based compute module...youll always have a working shim!
[15:28] <MY123> uuhimhere, a true driver, not a shim

[15:28] <ali1234> sure, except when it doesn't work due to bugs :)
[15:28] <MY123> uuhimhere, you will be impressed by the Mesa work
[15:29] <MY123> ali1234, it will work
[15:29] <uuhimhere> is it mainlines yet
[15:29] <MY123> uuhimhere, mainline Mesa
[15:29] <uuhimhere> is it stable
[15:30] <MY123> uuhimhere, 90% piglit pass
[15:30] <MY123> uuhimhere, and stable
[15:30] <ali1234> mesa is never stable
[15:30] <MY123> uuhimhere, even Unity runs on it
[15:30] <ali1234> nvidia-glx or don't bother
[15:30] <uuhimhere> would wayland run on the pi
[15:31] <ali1234> it does, kind of
[15:31] <ali1234> you can only use weston
[15:31] <ali1234> and you can only have 64 surfaces, unless they fixed that bug
[15:32] <ali1234> and it uses massive amounts of ram because of compositing

[15:32] <uuhimhere> wayland doesnt have to use compositing right

[15:33] * Wetmelon (~wetmelon@97-82-222-162.dhcp.hckr.nc.charter.com) has joined #raspberrypi
[15:33] <ali1234> it would be worse that X11 if you did that

[15:37] <shiftplusone> just linking it as the page to check out.
[15:37] <uuhimhere> shiftplusone, ok so its a nice little thing that i cant have
[15:38] <uuhimhere> :P
[15:38] <uuhimhere> anholt hasnt updated since last year
[15:38] <uuhimhere> october
[15:38] <uuhimhere> thats like 6 months
[15:38] <shiftplusone> the VC4 page was updated last month
[15:38] <shiftplusone> 2015-02-17
[15:38] <uuhimhere> yeah
[15:39] <shiftplusone> he hasn't blogged about it recently, but that doesn't mean he hasn't been busy.
[15:39] <ali1234> writing graphics drivers is hard
[15:40] <uuhimhere> i thought he got moved onto another project or something because its been quiet
[15:40] <MY123> uuhimhere, it can
[15:40] <uuhimhere> and the driver's not been updtreamed?
[15:41] <shiftplusone> I think anholt upstreams things as he goes. I've certainly seen some patches to the pi kernel from him on the mailing list recently.
[15:42] * waveform (~dave@waveform.plus.com) has joined #raspberrypi
[15:43] <uuhimhere> shiftplusone, so how much work would it take to have the pi2's module used with the pyra's board; how much functionality would go out the window?
[15:43] <shiftplusone> I don't know, one board doesn't even exist yet and I don't have the other.
[15:43] <ali1234> are there any specs at all for the module interface?
[15:44] <uuhimhere> i guess its too early
[15:44] <ali1234> i mean potentially everything from impossible to 100% functionality
[15:44] <uuhimhere> well surely theres wnough there to get bare metal
[15:44] <shiftplusone> everything is possible with enough electronics in between and time to spend on it.
[15:45] <ali1234> like connecting a screen to the DSI port?
[15:45] <uuhimhere> shiftplusone, yeah because its modular something in between is possible
[15:45] <uuhimhere> heh?

[15:45] <uuhimhere> they are using a mipi screen

[15:46] <uuhimhere> last i checked they are actually using a portrait screen with a rotator chip to get landscape
[15:46] <uuhimhere> pyra
[15:46] <ali1234> well that should work then, if you can reverse engineer the DSI hardware in the pi
[15:46] <ali1234> which actually probably isn't all that hard
[15:46] <uuhimhere> why it isnt "open"
[15:46] * pksato (~PEBKAC@unaffiliated/pksato) has joined #raspberrypi
[15:46] <uuhimhere> i thought dsi was just a framebuffer output?
[15:47] <ali1234> pretty much
[15:47] <ali1234> technically the pi doesnt have a framebuffer
[15:47] <ali1234> it has a hardware compositor instead
[15:47] <ali1234> the console/x11 framebuffer is just a hack to make it work
[15:47] <shiftplusone> is there documentation for the screen?
[15:48] <uuhimhere> shiftplusone, for the one theyre using?
[15:48] <shiftplusone> yeah
[15:48] <uuhimhere> shiftplusone, probably on the forums
[15:48] <MY123> uuhimhere, the driver is on github.com/anholt/linux
[15:48] <MY123> branch vc4-3.19
[15:48] <uuhimhere> ok i take it he hasnt pushed it?
[15:49] <shiftplusone> I doubt he can push it all at once. The review for even the tiniest changes is brutal >_<

[15:50] <uuhimhere> shiftplusone, thats still a long way from getting a pi-pyra :(
[15:50] <uuhimhere> shiftplusone, besides why dont you just use one thats in a phone with a vc4?
[15:51] <shiftplusone> reasons
[15:51] <ali1234> you know the hardest part about connecting a mipi screen? the damn ribbon cable...
[15:51] <ali1234> is there a breakout for it?
[15:52] <uuhimhere> on what the phone?
[15:52] <ali1234> for the 15 way ribbon cable
[15:52] <SpeedEvil> ali1234: no
[15:52] <SpeedEvil> And the hardest part is the driver
[15:52] <ali1234> someone should get on that...
[15:52] * AbouEmre1 (~Thunderbi@ Quit (Quit: AbouEmre1)

[15:53] <SpeedEvil> I should have read more backscroll
[15:53] <SpeedEvil> Making a little board with a couple of connectors on, one to go to an existing display, the other to the PI is nott very hard.
[15:53] <ali1234> i bet i could get it working, if i had a mipi screen with the 15 way connector
[15:53] <shiftplusone> I'd solder little wires from the pi's stock cable to the pads for the screen, get it to work, then get some sort of adapter made.
[15:53] <SpeedEvil> It requires SM skills, and to order a board
[15:54] <ali1234> and to find a compatible screen
[15:54] <SpeedEvil> Ah - I was being lazy and meaning no hand-soldering at all, just use connectors

[18:23] <mattbrejza> raspistill
[18:24] <waveform> mattbrejza, by exposure do you mean the shutter speed or the sensor gain (or both)?
[18:25] <mattbrejza> well shutter i guess
[18:25] <mattbrejza> main thing is that it will consistantly expose an image the same
[18:25] <mattbrejza> as i dont trust the cam to do a good job all thetime, so i want to manually find the right settings and lock it
[18:25] <waveform> shutter speed is pretty easy: use the -ss parameter to specify the speed
[18:25] <Froolap> You want 30 second exposure for taking pictures of stars...
[18:26] <mattbrejza> oh right, i didnt see -ss in the help
[18:26] <Hix> --shutter, -ss Set shutter speed
[18:26] <mattbrejza> thanks
[18:26] <clever> ozzzy: i have ran some ds18b20's on my pi, but it doesnt perform nearly as well as a 5v avr
[18:26] <mattbrejza> i was looking in a pdf rather than the -help
[18:26] <Hix> though apparently it has a time limit of ~6s
[18:26] <clever> ozzzy: i suspect its a combination of the lower voltage rail and the weak io drivers on the pi pins
[18:26] <waveform> but bear in mind it's limited by the framerate, so if you want say a 1s exposure you need to set the framerate to 1fps or less
[18:26] <shiftplusone> have a read of the readme https://github.com/raspberrypi/userland/blob/master/host_applications/linux/apps/raspicam/README.md
[18:26] <clever> since the avr can sink up to 20mA per pin
[18:27] <waveform> mattbrejza, however you need to be aware that that won't lead to *completely* consistent captures because the sensor gain isn't fixed
[18:27] <Hix> what was the name of the super-lightweight OS for pi?
[18:27] <mattbrejza> ok, can you fix the gain?
[18:28] <waveform> mattbrejza, this is harder because the firmware provides no way to specify the gain you actually want. All it provides is a means to disable the AGC algorithm, leaving the current gains static
[18:28] <mattbrejza> it doesnt have to be super consitant between images
[18:28] <mattbrejza> oh ok
[18:28] <waveform> in that case I'd just play with shutter speed for now - gains are tricky to fix nicely
[18:29] <mattbrejza> ok should be enough, thanks
[18:29] <ozzzy> you could test that.... run the sensors at 5V and put a divider in to bring the data line down to 3.3 (between the pin and the pullup)

[18:35] <DoctorD90> to control rpi, i had installed network-manager and setup usb connection, using my tablet usb-tethering. to achive this, without network-manager, may i add "usb auto" in network file?
[18:35] <Peio> you can install a 300MB raspbian with the net installer Hix
[18:35] <huleo> there is some script flying around doing just that (+taking care of kernel/bootloader config)
[18:35] <shiftplusone> Hix, it can, but you'd need to know what you're doing. If boot time is really important then yeah, stick with buildroot.

[18:56] <ivh> picam, I was hard tempted to get the noir instead though.
[18:56] <giddles> ill use noir and irlights
[18:56] <giddles> :)
[18:57] <giddles> works fine in monochrome color
[18:57] <ivh> but I know a bit about ccds and coulr program the picam to do properly exposed long night exposures instead.

[19:09] <Cheekio> disagree
[19:09] <Cheekio> PI2 has very little on google
[19:10] <mgottschlag> I don't think there are large differences between pi and pi2, except for additional power
[19:10] <shiftplusone> because it's the same thing as a pi1, but with an a7.
[19:10] <Cheekio> No, you've got a point. Pi1 projects can (universally?) be done with a pi2
[19:10] <Cheekio> I guess I agree
[19:11] <Cheekio> Still though, projects that need the extra 3 cores are few and far between

[19:21] <shiftplusone> well... in most tasks it's as fast as you'd expect the v6 to run at the same clock rate.
[19:22] <shiftplusone> only where NEON is used do you actually see significant boosts.

[19:24] <ShadowJK> the A7 should have an IPC advantage
[19:24] <Anorion> I imagine there will be gains in other areas
[19:24] <Anorion> having a dedicated core for all of the linux.system stuff means the other three are completely free
[19:25] <ShadowJK> Although I'm not too familiar with A7, it's the "sensible" A9, which was an upgrade to A8, which had a bit of a narrow front-end but could issue 2 instructions per cycle
[19:25] <Ryccardo> actually it tries to spread processes between all cores, AFAIK
[19:25] <shiftplusone> ShadowJK, not the way software in debian seems to be compiled. If there's any IPC advantage, it doesn't translate to a noticeable improvement in the user experience.
[19:25] <Anorion> maybe for the pi3
[19:25] <methuzla> datacide are you looking for general pi projects, or ones specific to pi2?
[19:25] <Anorion> Ryccardo, yeah, but you can change that yourself
[19:26] <Froolap> I'll take either.
[19:26] <shiftplusone> Though benchmarks for ubuntu seem to indicate there's a bit of an improvement (something like 15%, which is... significant).
[19:26] <shiftplusone> I haven't verified that myself though =/
[19:27] <ShadowJK> shiftplusone; ipc gains, and to some extent cpu speed, don't tend to be that important for "interactive" stuff
[19:27] <Froolap> but will it let me irc faster?
[19:28] <shiftplusone> sunspider, application startup, page loading times, sysbench... I couldn't find anything where it makes a difference other than NEON stuff
[19:28] <Stephini> something like this would have no use in pi projects i'm guessing? found one in my grandad's old tools. http://www.amazon.com/DiversiTech-Corporation-EM111-Tester-60-500v-Ac-Dc/dp/B008FM41OQ
[19:29] <Anorion> useful for testing circuits, but less so than a multimeter
[19:29] <shiftplusone> heh, Stephini. Do you plan to test any neon bulbs?
[19:29] <Stephini> i was thinking maybe it would be able to test continuity. *shrug* just a thought. :P
[19:30] <Cheekio> Anyone have a nice usb keyboard they'd recommend?
[19:30] <Anorion> Poker 2
[19:30] <Stephini> Anorion, i was thinking the same thing. i cant afford a decent multi right now so thought maybe i could start moving on my projects with this. :P
[19:30] <Anorion> if you like 60% boards
[19:30] <Stephini> Cheekio, razer anansi
[19:30] <shiftplusone> Cheekio, what are you looking for in a keyboard?
[19:30] <Anorion> Stephini, I have a cheapo one from HArbor Freight
[19:30] <Anorion> like $0.99
[19:30] <Anorion> it works well enough
[19:31] <Cheekio> To connect it to my rpi
[19:31] <Cheekio> as a keyboard / mouse solution
[19:31] <Stephini> 99 cent multi? wow that really wouldn't be aproved by eevblog i'm guessing.
[19:31] <shiftplusone> given those parameters.... any keyboard.
[19:31] <Anorion> nope, it gives you an order-of-magnitude accuracy, and direction
[19:31] <Stephini> Cheekio, i use a logitech wireless keyboard with multitouch pad for media center.
[19:31] <Anorion> Stephini, cheapo ones are fine
[19:32] <Stephini> Anorion, eevblog kept saying cheapos can be dangerous to the end user is what i was saying. :P
[19:32] <Anorion> I demand a mechanical board for everyday use, though
[19:32] <Anorion> Stephini, I've had it for years, and it works fine
[19:32] <Stephini> ohh i got signals crossed. thought you were talking about the multi not the keyboard. >.<
[19:33] <Anorion> sorry, both
[19:33] <Anorion> so did I
[19:33] <Ryccardo> a super crapola one I have is quite incorrect (0,3 ohms by shorting the sockets), but an equal design I have is fine
[19:33] <shiftplusone> I use this one at work. http://support.logitech.com/product/illuminated-keyboard At home I use a razer blackwidow stealth. Considering getting a unicomp keyboard.

[19:35] <Anorion> if you really want to get into keyboard lore, hit up /r/mechanical_keyboards
[19:35] <Cheekio> I'm probably going to go the WASD route for work
[19:35] <Stephini> the M keys are 5 keys to the left of the main board that can be programmed and the T keys are modifier keys. 7 keys that handle every combination of alt shift and control.
[19:35] <shiftplusone> Stephini, I don't understand 60% and tenkeyless keyboards. Can't stand to use them.
[19:35] <Cheekio> I type dvorak, so... yeah. Might as well.
[19:36] <Cheekio> Tenkeyless?
[19:36] <Stephini> Cheekio, wasd? you mean qwerty?
[19:36] <Anorion> wasd is a brand
[19:36] <shiftplusone> Cheekio, without the numpad on the right
[19:36] <Stephini> tenkeyless?
[19:36] <Cheekio> No, I mean the worst brand named keyboards on the planet: wasdkeyboards.com
[19:36] <Stephini> ahh.
[19:36] <Cheekio> Though I do like my numberpads
[19:37] <shiftplusone> some people seem to hate numbers.
[19:37] <Stephini> i can't live without my anansi and naga combo anymore. gimp, blender, games...everywhere i am so reliant on the extra buttons.
[19:37] <Stephini> shiftplusone, i can get that although for my HTPC i dont ever need the top numbers so loosing the keypad is no big.
[19:38] <shiftplusone> sure, for an htpc, I can understand.
[19:38] <shiftplusone> For a workstation... bah.
[19:39] <Stephini> i actually use the keypad alot less since i got the naga. i do most of my number entry by thumb now.
[19:39] <Ryccardo> my PC has no numpad (not even the fn+letters on the right) and I haven't really missed it

[19:43] <Cheekio> Froolap, I've turned them off via xset for the xserver
[19:44] <Cheekio> `xset q` tells me that dpms and blanking and exposures are off
[19:44] <Ryccardo> Stephini: now, if someone made a numpad with modifier keys just under it...
[19:44] <Cheekio> Also, I made a script to turn of dpms and blanking while omxplayer was running, and it didn't cause the issue

(basically where would i get the male and female that i splice into the cable i already have.
[19:54] <buZz> ah ok you are still booting kernel from SD
[19:55] <buZz> cp -rxp / /mnt/usb
[19:55] <Mutantx> Unfortunately..
[19:55] <buZz> should do it fine

[19:55] <Mutantx> Woudl the HD only have 1 partition?

[20:00] <Cheekio> The pi is more powerful than the wii?
[20:00] <Cheekio> That can't be right
[20:00] <buZz> Stephini: adafruit.com has some plugs
[20:01] <Ryccardo> Cheekio: maybe the cpu is better (only the powerpc is used in Linux), memory is a definite bottleneck

[20:18] <turtlehat> whats hellish about your time, Cheekio
[20:19] <codestorm> thanks methuzla and Ryccardo
[20:19] <Cheekio> I've been debugging a video issue for days now: http://www.raspberrypi.org/forums/viewtopic.php?f=28&t=104055
[20:20] <Cheekio> short story is that omxplayer craps out after 20 minutes. Nothing interesting in the logs.
[20:20] <Cheekio> I'm trying to install vlc now, because I think kodi uses omxplayer and I was getting the same issues in kodi as I'm getting now in raspbian
[20:20] <turtlehat> oh omxplayer runs smooth for me
[20:20] <turtlehat> but im getting segfaults from programs in x, left and right
[20:20] <turtlehat> :|
[20:20] <shiftplusone> Cheekio, if you've ruled everything out, you can send your full set up in for testing.
[20:21] <Cheekio> I'd be happy to
[20:21] <Cheekio> I've got 2 pis that had this issue
[20:21] <Cheekio> 2 pi2s*
[20:21] <shiftplusone> cool, I'll check with the powers that be and let you know tomorrow.
[20:21] <Cheekio> So I can keep hacking on one while I have the other one sent in. I think it's an omxplayer issue

[20:23] <shiftplusone> ah, a bit on the pricey side to post to the UK then, I guess.
[20:24] <Cheekio> turtlehat, have you been watching things on omxplayer, or did you just test it?
[20:24] <Cheekio> It takes ~20 minutes of video for the issue to show up
[20:24] <turtlehat> Cheekio, i watch movies often
[20:24] <shiftplusone> does the pi itself hang or is it just video?
[20:25] <turtlehat> same time as i use other stuff
[20:25] <Cheekio> Just omxplayer
[20:25] <turtlehat> omxplayer runs smooth here
[20:25] <Cheekio> If I give it a minute, I can esc out of it and restart omxplayer
[20:25] <Cheekio> on Kodi, it would do the same thing but it would crash the video player back to the file selection menu
[20:26] <shiftplusone> Cheekio, have you checked vc logs?
[20:26] <Cheekio> vcdbg? Yeah
[20:26] <shiftplusone> anything?
[20:26] <Cheekio> Let me pull them out, I saved them to a file
[20:26] <Cheekio> it didn't look promising

[20:27] <shiftplusone> It sounds a bit like a memory leak
[20:27] <Cheekio> Oh yeah,
[20:27] <Cheekio> Bunch of "hdmi: HDMI: Action" calls around the failure
[20:27] <shiftplusone> but then you wouldn't be the only one with the problem
[20:27] <Cheekio> It looks like the first one was "hdmi: HDMI: power_on to CEA mode 1080p60"

[20:28] <Mutantx> Ryccardo: I've added - UUID="0specificuuid" /root ext4 defaults 0 0 to fstab- and now the only thing I need to change is root=/dev/mmcblk0p2 to /root right?
[20:28] <Cheekio> then like a dozen or so hdmi: HDMI: Action <detach added to queue> < change_mode added to queue> etc
[20:28] <Ryccardo> Mutantx: waaaait
[20:28] <Cheekio> shiftplusone, I actually checked for memory usage- the GPU may be eating up its memory and crashing, but the OS doesn't know about it
[20:28] <Mutantx> should i make it /dev/sdba instead?
[20:29] <Cheekio> omxplayer never took up as much as 6% of the total memory throughout playback
[20:29] <shiftplusone> Cheekio, vcdbg provides a way to view the gpu memory usage as well... I think it spits things out in gnuplot-friendly format.
[20:29] <edjuh> here my browsers keep crashing, otherwise a smooth ride
[20:29] <Ryccardo> 1- no quotes in fstab or cmdline (enven though blkid prints them), 2- you'd want it to mount to / (/root is another thing), 3- parameter in cmdline is a device and not a partition (so root=/dev/sda1 or root=UUID=whatever)
[20:29] <shiftplusone> Anyway... I think I'll need to get the logs of you and show them to Dom.
[20:29] <Cheekio> I use 'sudo vcdbg log msg'
[20:30] <zeeshan> for the raspberry pi 2, whats the limitation on current for the 5v and 3.3 v pin on the gpio header
[20:30] <shiftplusone> zeeshan, depends on the usage by other things.
[20:30] <Cheekio> I guess I should read up on vcdbg
[20:30] <edjuh> zeeshan 700 mA
[20:30] <zeeshan> shiftplusone: usage of what
[20:31] <shiftplusone> O_o... current.
[20:31] <Ryccardo> Mutantx: so →→ UUID=whatever / ext4 defaults 0 1 ←← in fstab, root=UUID=whatever in cmdline
[20:31] <zeeshan> im asking for a max limit.
[20:31] <zeeshan> thanks edjuh
[20:31] <shiftplusone> ah, as long as we can make up random numbers.
[20:31] <zeeshan> im trying to use the 5v to excite a bridge
[20:32] <zeeshan> and 3.3 to power my ads1220 chip
[20:32] <edjuh> zeeshan by heart, rather check.

[20:33] * j416 (~j416@unaffiliated/j416) has joined #raspberrypi
[20:34] <Ryccardo> the +5 from the GPIO area is current limited though (if they didn't change that)
[20:35] <shiftplusone> 1A from the 3.3v line total
[20:35] <shiftplusone> but I'm not sure you got the point that GPIO isn't the only place those are used
[20:36] <shiftplusone> you need to take into account that usb devices draw from the 5v line and other things do too. Same goes for 3.3v
[20:36] <Mutantx> Ryccardo: Ah ok so just point specifically to the UUID rather than the folder that is mounted by fstab?
[20:36] <shiftplusone> Ryccardo, a limit that's not important here. It was bumped up on the b+/pi2. The real limiting happens for USB only.
[20:37] <zeeshan> shiftplusone: i understand other places use the current
[20:37] <Ryccardo> Mutantx: I typoed the message with the 3 corrections, but in cmdline you never enter a mountpoint, always a block device or an abstraction (label, uuid, ...)
[20:37] <zeeshan> i just wanted an absolute maximum
[20:37] <Ryccardo> shiftplusone: another reason to upgrade :/
[20:37] * mumixam (~m@unaffiliated/mumixam) has joined #raspberrypi
[20:38] <zeeshan> also one more q
[20:38] <shiftplusone> Just checked... the fuse has a 2A hold current. 4A trip
[20:38] <edjuh> shiftplusone: never the less, external power does not hurt a bit, if you want to run above 500 mA (my magic number) in total that is (ex USB)
[20:38] <zeeshan> can any of the gpio serve as chip selects?
[20:38] <shiftplusone> zeeshan, yes
[20:38] <zeeshan> okay, perfect this will work great. thank you!
[20:39] * zeeshan invests time in reading the manuals
[20:39] <shiftplusone> I wouldn't draw anywhere near those currents through a single pin though
[20:39] <ali1234> does anyone else smell smoke?
[20:39] <zeeshan> im going to be in the 50 - 150mA range max
[20:39] <shiftplusone> Oh, you're fine... except for maybe on the 3.3v line.
[20:40] <Cheekio> The rumors of gcc failing on make install when trying to install the latest vlc... are true
[20:40] <ali1234> gcc? make install? whaaaaat?
[20:41] <Cheekio> uh
[20:41] <Cheekio> This is out of my league, I thought gcc was what actually compiled code
[20:41] <Cheekio> is g++ the compiler? What does that make gcc?
[20:41] <ali1234> neither of them INSTALL things
[20:42] <Ryccardo> g++ is an alias for `gcc {some defaults for c++}`
[20:42] <ali1234> at what point does it actualy fail?
[20:42] <Ryccardo> and yes, you generally must `make` before `make install` (and often `./configure` before both)
[20:42] <shiftplusone> Cheekio, Don't worry, ali1234 is just being pedantic >_<. Though it certainly helps to get the terminology right and sgive the specific problem (pastebin the whole thing), if you actually want support.
[20:43] <ali1234> 'make install' typically requires sudo
[20:43] <Cheekio> http://www.oblivion-software.de/index.php?id=56&type=98

[20:47] <zeeshan> the 3.3V line is generated with an onboard regulator?

[20:48] <zeeshan> yes but for initial startup

[21:38] <shiftplusone> Encrypt, certainly... wiringpi does, after all.
[21:38] <ali1234> yes, it's possible. just open /dev/mem and write away
[21:38] <shiftplusone> Encrypt, ^ that. Or use the kernel driver.
[21:39] <Encrypt> Ok :
[21:39] <Encrypt> :]
[21:39] * Gathis (~TheGrey@unaffiliated/gathis) has joined #raspberrypi
[21:40] <ali1234> at least this explains why the serial console doesn't work

[21:41] <ali1234> that's the kernel driver
[21:42] <shiftplusone> Encrypt, that's the 'correct' way to do it, yes.
[21:42] <shiftplusone> The hacky, faster, frowned-upon way is to poke the memory directly.
[21:42] <ali1234> it won't be fast doing it that way, but depending on what you want to do, that probably won't matter
[21:42] <shiftplusone> you can check the wiringpi source code

[21:52] <Cheekio> I'm using sshfs to mount the drive, then using omxplayer to run the file as if it's on a mounted drive
[21:52] <shiftplusone> okay, seems like something I can easily test here

[21:52] <ali1234> probably out of memory
[21:53] <Cheekio> Maybe the GPU is, but I checked running processes- nothing over 6% of available system memory
[21:53] <ali1234> sure, after it has crashed

[21:54] <shiftplusone> ali1234, afaik, VC adjusts sdram clocks based on temperature (or something). And of course it's needed to bring the ARM up in the first place.
[21:54] <Cheekio> watch 'echo `date` && ps aux | awk '"'"'{print $2, $4, $11}'"'"' | sort -k2rn | head -n 10 >> mem_top.txt'
[21:54] <Cheekio> ^^ ali1234 check that shit out
[21:55] <ali1234> did you just reimplement top?
[21:55] <Cheekio> for memory, to a file
[21:55] <Cheekio> You can do top M, but then you don't get it output to a file
[21:55] <Cheekio> So... short answer, yeah, I checked memory during omxplayer runtime

[21:57] <ali1234> ^ try that

[22:01] <ali1234> looks interesting, thanks
[22:01] <ali1234> what else is new?
[22:01] <shiftplusone> well, more-so.
[22:02] <ali1234> my reasoning is that it would be easier to poke around if i'm not stomping on the VC
[22:02] <ali1234> then i can take direct control of eg. pixel pumps from ARM, and not have to fight another CPU doing things i can't trace
[22:02] <shiftplusone> that's my123's thing. I still haven't quite figured out if he knows stuff or just thinks he does, but it does seem like he was able to bring the ARM up from his own start.elf equivalent.
[22:03] <ali1234> yeah, so minimal start.elf + phire's monitor envionment = many hacks
[22:04] <shiftplusone> there's a big gap between 'bringing the ARM up' and 'doing something useful on it'. You don't just get to run linux straight away.

[22:22] <zacts> is it true that the rpi requires proprietary firmware to run?
[22:22] <antokara> ok so I bought RPi2 and having problems since day one. For starters I must say that with the same HDMI cable/tv I have no problems with my old pi type b. The problem with pi2 is that I get "bad pixels" without hdmi boost 6 and video playback stutters unless I set audio output to analog. go figure!
[22:23] <Xark> zacts: Yes. But only on GPU side, I believe (ARM is totally open).

[23:41] <Xark> pizearke: Also ARM QEMU images if you want to try running...
[23:43] * drag0nius (~drag0nius@acgs22.neoplus.adsl.tpnet.pl) has joined #raspberrypi
[23:44] <drag0nius> any idea if rpi (512MB version) can handle 2 usb ethernet adapters?
[23:44] <drag0nius> without powered hub
[23:44] <Froolap> I have been running 2 wireless dongles on my pi. banana as well as raspberry
[23:45] <Froolap> connected directly to the pi, 2A power supply

[23:46] <Xark> drag0nius: You may need in config.txt max_usb_current=1
[23:46] <Froolap> but, that's not to say that it can handle ANY or all combinations of wireless adapters without the aid of a powered hub.
[23:46] * soulcake (~soulcake@unaffiliated/soulcake) Quit (Quit: Quack.)
[23:47] <Froolap> it may well be that it only likes my combination of wireless keyboard and wireless dongle.

[23:49] <pizearke> I'm not using a very fast computer at all
[23:49] <pizearke> Best to stick with reading and writing

[23:52] <Criggie> pizearke: pish tosh. I ran a win98 VM on a linux P3 700 with 256 MB ram. The VM had 64 MB ram and it "ran" "okay" if you were patient
[23:52] <jlf> luxury!
[23:53] <Criggie> "uphill, both ways!"
[23:53] <pizearke> you say that
[23:54] <pizearke> I have trouble opening notepad
[23:54] <pizearke> okay dumb question
[23:54] <ozzzy> buddy of mine wrote a windows text editor in assembly (he's a masochist)... ran like a raped ape
[23:54] <pizearke> any positive number in two's complement notation is going to be the same as it is in regular notation, right?

[23:57] <Froolap> I wonder how well dosbox could run on a pi and play wing commander with usb cd-rom
[23:58] <willmore> pizearke, yes.
[23:58] <pizearke> ok swell
[23:58] <ozzzy> it runs well
[23:58] <ozzzy> I haven't played games with it
