| pcpower | NekoXP: I want to use pins for GPIO inside of ubuntu | 00:11 |
|---|---|---|
| pcpower | it seems like I have to recompile x-loader and change some header or something, in order to do that | 00:11 |
| pcpower | and I just have no idea where to start | 00:11 |
| NekoXP | not sure why you'd be required to change x-loader? | 00:11 |
| pcpower | all I want is a couple gpio pins on the physical board I can set high and low | 00:11 |
| pcpower | NekoXP: I think because it's defaulted that the pins are setup as GPMC/i2c and other things | 00:12 |
| pcpower | and not GPIO | 00:12 |
| pcpower | the pins are all 2 or 3-purpose | 00:12 |
| NekoXP | you should be able to do that in the kernel | 00:12 |
| NekoXP | it's the wrong place but you can do it | 00:12 |
| NekoXP | I've not done any omap4 stuff but there should be some kind of pinmux stuff around you can kick.. isn't there a pin header on the board anyway? | 00:14 |
| NekoXP | my panda's at the office... | 00:15 |
| prpplague | NekoXP: yes the proper place is the kernel, however pcpower has no experience doing any dev work, he just needs to know where one gpio is already configured | 00:18 |
| prpplague | NekoXP: gpio 139 and 140 are already configured | 00:19 |
| NekoXP | schematic :D | 00:19 |
| NekoXP | I disagree that pinmuxing should be done so late, but :_ | 00:19 |
| NekoXP | if you need to just hack around it's much quicker in the kernel | 00:19 |
| prpplague | NekoXP: schematic doesn't tell you what the software is configured for | 00:20 |
| NekoXP | yeah but if you want to change it who cares what it's already configured for | 00:20 |
| NekoXP | you just need to find some pins which are on the board but not connected to some other device | 00:21 |
| NekoXP | hopefully with no pullups or pulldowns or weird stuff | 00:21 |
| prpplague | NekoXP: thats the whol point, he doesn't want to compile anything, he just wants to know that is already configured | 00:22 |
| prpplague | NekoXP: i already gave it to him anyway | 00:22 |
| NekoXP | so I answered him already :) /sys/class/gpio has a list of pins configured as gpio and cross referencing would have found which ones were free and where on the board they are | 00:25 |
| prpplague | NekoXP: no that is no correct | 00:26 |
| NekoXP | really? is panda that much different to any other board using gpiolib? | 00:27 |
| prpplague | NekoXP: if the gpio hasn't been exported, it will not show up in /sys/class/gpio | 00:28 |
| NekoXP | hmm yeah I guess you have to request it first | 00:29 |
| NekoXP | but if 139 and 140 are already configured that's implied | 00:29 |
| prpplague | NekoXP: only the pinmux is configured, doesn't mean it has been requested | 00:32 |
| NekoXP | okay so he needs to kick around in the kernel anyway | 00:32 |
| NekoXP | ? | 00:32 |
| prpplague | NekoXP: no, he just needs to export the gpio | 00:33 |
| prpplague | GrueMaster: ping | 00:33 |
| prpplague | GrueMaster: where the heck is the x-loader source for maverick omap4 support? | 00:33 |
| GrueMaster | Couldn't tell you off hand. I'd have to load a system with maverick and then look at a package. | 00:35 |
| GrueMaster | let me see if I can find it by other means | 00:35 |
| prpplague | https://launchpad.net/ubuntu/maverick/+source/x-loader-omap4 | 00:36 |
| prpplague | GrueMaster: nm, found it | 00:37 |
| GrueMaster | I was looking for the git tree. | 00:37 |
| GrueMaster | But that works. | 00:37 |
| prpplague | GrueMaster: getting killed with people wanting to do i2c and gpio from 10.10 lately | 00:39 |

| siji | Good After noon friends | 07:34 |
| siji | need some help to enable my beagleboard XM with touch screen | 07:36 |
| siji | it's TSC 2046 Controller | 07:37 |
| siji | and I have "insmod" ads7846.ko (2.6.38-8) | 07:38 |
| siji | but evtest is not responding for touch events | 07:39 |
| siji | any help pls | 08:03 |
| siji | persia, u there? | 08:34 |
| siji | ogra_, you there | 12:00 |
| siji | [ 956.874450] ads7846: disagrees about version of symbol module_layout | 12:00 |
| siji | means wrong driver module right ? | 12:00 |
| ogra_ | yes | 12:00 |
| ogra_ | how did you build it ? | 12:01 |
| siji | am wondering how it's happen, i have build the OS image from rootstock | 12:01 |
| ogra_ | i mean how did you build that module | 12:01 |
| siji | ogra_, it was there bydefault | 12:01 |
| siji | in the rootstock build image | 12:02 |
| ogra_ | cant be :) | 12:02 |
| siji | yes, it is | 12:02 |
| siji | :) | 12:02 |
| ogra_ | there is no kernel in rootstock images by default | 12:02 |
| siji | linux-omap | 12:02 |
| ogra_ | so that cant be | 12:02 |
| ogra_ | unless you forcefully added one | 12:02 |
| siji | i hve added the parameter linux-omap | 12:03 |
| ogra_ | ?? | 12:03 |
| ogra_ | the message above means that your module was compiled differently from the rest of the kernel ... that simply cant happen in a packaged kernel | 12:04 |
| siji | right.. | 12:04 |
| siji | i did seed linux omap | 12:04 |
| ogra_ | so check what kernel packages you have installed | 12:05 |
| siji | while building rootstock | 12:05 |
| siji | ok | 12:05 |
| siji | ogra_, i have build the rootstock with the parameter --seed linux-omap | 12:07 |
| ogra_ | did you check your installation ? | 12:08 |
| siji | yes | 12:08 |
| siji | it seems like everything is fine | 12:08 |
| siji | running on kernel 3.6.38-8 omap | 12:09 |
| ogra_ | locate ads7846 | 12:10 |
| ogra_ | where is that located | 12:10 |
| siji | /lib/modules/kernel/--- | 12:10 |
| ogra_ | where exactly | 12:10 |
| ogra_ | i dont see it being built in any of our arm kernels | 12:11 |
| ogra_ | ogra@panda:~$ locate ads7846 | 12:11 |
| ogra_ | ogra@panda:~$ | 12:11 |
| siji | /lib/modules/2.6.38-8-omap/kernel/drivers/input/touchscreen | 12:11 |
| ogra_ | definitely not enabled on omap4 | 12:11 |
| ogra_ | very strange | 12:11 |
| ogra_ | oh, i see, on omap4 it is compiled in | 12:12 |
| siji | oh.. | 12:12 |
| siji | but mine is omap3 | 12:12 |
| siji | beagleXm | 12:12 |
| ogra_ | right, i dont have one running here so i cant check | 12:12 |
| siji | ok | 12:12 |
| ogra_ | file a kernel bug then against the linux package (mention omap3 in the description) | 12:13 |
| siji | ok | 12:13 |
| ogra_ | though that still doesnt explain the error | 12:13 |
| ogra_ | and i think only the kernel or touch teams could help here | 12:13 |
| siji | ok | 12:13 |
| siji | or I have to build the kernel here right? | 12:14 |
| ogra_ | you could do that too, indeed, or try one of rcnee's kernels (there is a PPA somewhere with his kernel packages) | 12:15 |
| siji | i have tried but failed to enable SGX driver | 12:15 |
| siji | anyway will give a try again | 12:15 |
| ogra_ | make sure to file bugs if you find issues ;) | 12:15 |
| siji | sure will do | 12:16 |
| hrw | nvflash looks fun | 14:30 |
| ogra_ | heh | 14:30 |
| hrw | nightmare kind of fun | 14:31 |
| ogra_ | what for do you need it ? | 14:31 |
| hrw | ogra_: Hannspree hannspad - cheap android 10.1" tablet | 14:32 |
| ogra_ | ah | 14:33 |
| ogra_ | well, if you have a good kernel you should only have to use nvflash once | 14:33 |
| ogra_ | i.e. a good kernel like the ac100 one wheer you can see the boot partitions from userspace :) | 14:33 |
| hrw | problem is that there are no good kernels for it. vendor 'forgot' to give gpl source so kernels from community only and they lack few things | 14:35 |
| ogra_ | did someone report it as gpl violation already ? | 14:35 |
| hrw | checking that is on my todolist | 14:36 |
| ogra_ | well, generally the chromeos kernels are a good start for tegra stuff | 14:37 |
| cjwatson | Hi, I can't figure out why https://launchpadlibrarian.net/76889732/buildlog_ubuntu-oneiric-armel.libvirt_0.9.2-4ubuntu8_FAILEDTOBUILD.txt.gz is failing; I don't *think* it's due to my change. Would somebody be able to have a look. | 14:40 |
| cjwatson | ? | 14:40 |
| ogra_ | me looks with no promises that he has more clue | 14:45 |
| ogra_ | wow, looks really bad | 14:50 |
| infinity | cjwatson: Is that a python testsuite? | 14:55 |
| infinity | cjwatson: If so, I imagine it relates to https://launchpadlibrarian.net/76841318/buildlog_ubuntu-oneiric-armel.python-apt_0.8.0ubuntu3_FAILEDTOBUILD.txt.gz | 14:55 |
| ogra_ | well, doesnt look like anything used libnl3 on arm before | 14:56 |
| cjwatson | infinity: not seeing the link ... | 15:01 |
| cjwatson | (but I don't actually know, I'm entirely new to libvirt and was just trying to get everything shifted over to libnl3) | 15:01 |
| ogra_ | cjwatson, wild guess: the missing classid file gets pulled by a netlink socket, our kernel on the ancient buildd HW misses bits the nl3 lib uses, so the dtd doesnt end up where it should be | 15:01 |
| ogra_ | (really wild guess) | 15:02 |
| infinity | Oh, I didn't look closely. I'm barely awake here. :P | 15:03 |
| infinity | Brain just saw two testsuites die. :P | 15:03 |
| ogra_ | i dont have a panda with a disk atm, but i can do a testbuild on an ac100 | 15:10 |
| ogra_ | to see if its machine related | 15:11 |
| rOxx | Hello, i want to test the uart port on the beagleboard xm with a oszilloscope to check the uboot configuration, i have disabled kernel pinmux. i know that uart2 is ttyO1, are there any possibily to send data over this port ? | 15:18 |
| fisuk | does anyone have any idea why i get inverted colors on my cursor and the xterm text, like this: http://dl.dropbox.com/u/952540/wtf.jpg | 15:47 |
| fisuk | if i swap to a text console and back to X, then they show up correctly | 15:48 |
| fisuk | also, there's no text showing up on any of the apps | 15:49 |
| fisuk | some underscores here and there, but mainly nothing is visible | 15:49 |
| ogra_ | what arch is that ? | 15:56 |
| fisuk | omap4, custom maverick rootfs, kernel 2.5.35-980-omap4 | 16:04 |
| fisuk | i have no idea what I've messed up because an earlier rootfs i built didn't have that problem.. | 16:05 |
| fisuk | well, i guess i'll just rebuild the thing for the millionth time. | 16:12 |
| fisuk | before that it'd be nice if i could even once get the video decoding hw accelerated, but there's no info about that on the wiki. or anywhere. i mean, there's the installation instructions for omap4-extras and "use totem", but no information about what videosink should be used when using gst-launch etc. or if any other pads are required. | 16:20 |
| ogra_ | it should just work out of the box in maverick | 16:21 |
| fisuk | oh | 16:21 |
| ogra_ | there are no codecs provided by TI for natty so dont bother to try it there (or bug TI) | 16:21 |
| ogra_ | we should get codecs for oneiric again | 16:21 |
| ogra_ | cjwatson, fyi, thats how the libvirt build fails for me in a oneiric chroot on an ac100 http://paste.ubuntu.com/662055/ | 16:33 |
| ogra_ | fails a lot earlier in test-chown | 16:35 |

| ericb2 | FYI, testing Nathy on Pandaboard, I got I/O errors with a brand new SD card ( Lexar, Class 10, 32GB). I can resize the partition, and at reboot -> nothing. After some investigations, I isolated this issue : http://paste.lisp.org/display/123918 | 22:06 |
| ericb2 | all the other cards I tested work as expected. The second 32GB I tested, has other problems : I got lot of I/O issues at runtime (e.g. compiling a big application), and the fs is remounted in read only mode | 22:08 |
| ericb2 | after some little search, the relevant code in the kernel is located in drivers/mmc/card/block.c | 22:09 |
| ericb2 | at least the error messages (say the what, not the why) | 22:09 |
| ericb2 | anybody aware of 1) existing issues ? 2) existing bug reports around that ? | 22:09 |
| ericb2 | thanks in advance for any help | 22:11 |
| ericb2 | :-) | 22:11 |
| infinity | You might just have bad cards. I have no issues here with an LX 32G Class 10. | 22:15 |
| MrCurious_ | ericb2: you any further in finding the cause? | 22:15 |
| ericb2 | infinity: thanks for the info | 22:27 |
| ericb2 | infinity: could this be another issue type, like the resize does something wrong, or I don't know ? | 22:28 |
| ericb2 | infinity: the problem is, I got other issues with the same disk image | 22:28 |
| ericb2 | infinity: like file system suddenly in read only mode, every time the machine has a good load or something similar | 22:29 |
| MrCurious_ | ericb2: i tried with a manually resized image, that was good. its not resize thats causing the problem | 22:29 |
| ericb2 | MrCurious_: thanks | 22:30 |
| MrCurious_ | np | 22:30 |
| ericb2 | MrCurious_: you avoided me to try myself :) | 22:30 |
| * ericb2 scratching his head | 22:31 | |
| ericb2 | MrCurious_: so we are two with problematic cards, both class 10 and high speed (at least this is written on the package) | 22:34 |
| ericb2 | other possibility could be a wrong high speed card, e.g. identified with high speed parameters and that's not true, causing timeout and worse | 22:35 |
| TheSeven | davidm: so it's now official that the scheduler is the culprit? | 22:39 |
| davidm | TheSeven, it's official it's a general ARM issue, not a Panda USB issue | 22:40 |
| davidm | likely scheduler but not completely sure about that | 22:40 |
| davidm | Was best rename I could come up with that fit what we are seeing | 22:40 |
| davidm | ope to suggestions for a better name | 22:40 |
| TheSeven | it would be interesting if this is only related to USB, I/O in general, or even every kind of thread execution | 22:41 |
| infinity | TheSeven: It's not just USB, and probably not just I/O. It really looks like it's spinlocking breakage. I'm assured that people smarter than me are looking deeper. | 22:42 |
| davidm | IT also makes a difference on writing to the SD card | 22:42 |
| MrCurious_ | my guess is it has hard coded timings that just work with slow cards, rather than detecting card state, allowing for it to run at max speed | 22:43 |
| MrCurious_ | or a hard coded wait that isnt needed with faster cards | 22:43 |
| davidm | infinity, I'm trying to get as many people as possible looking at it ;-P | 22:43 |
| MrCurious_ | if i had to "guess" | 22:43 |
| infinity | MrCurious_: I use a few class 10 cards (one even the same brand as ericb2) with no issues. | 22:45 |
| TheSeven | davidm: but compared with what's going on with USB storage, the differences on the SD interface were almost neglegible | 22:45 |
| TheSeven | s/with/to/ | 22:45 |
| MrCurious_ | rev c board? | 22:45 |
| infinity | TheSeven: Yes, but SD is slower by default, so sitting in idle loops 75% of the time doesn't hurt as much. :P | 22:46 |
| ericb2 | infinity: I believe you. Just searching how I can proof my reseler it is defective / not good | 22:46 |
| MrCurious_ | at least my board was rev c | 22:46 |
| ericb2 | infinity: this card is expensive (76 euros), and I'm not happy | 22:46 |
| TheSeven | ericb2: SD cards just aren't intended for compiling things on them | 22:47 |
| ericb2 | TheSeven: he he | 22:47 |
| ericb2 | TheSeven: I'm testing the armhf build on USB stick | 22:47 |
| ericb2 | TheSeven: on USB disk, it works. Trying the usb key now (more easy for traveling) | 22:48 |
| MrCurious_ | ericb2: usb is currently buggy, and possibly 10x slower than it should be | 22:48 |
| ericb2 | MrCurious_: promising ^^ | 22:48 |
| ericb2 | MrCurious_: I was wondering whether an sata support will arrive some day | 22:49 |
| ericb2 | would be fantastic | 22:49 |
| ericb2 | sata is reliable, really | 22:50 |
| GrueMaster | Doubtful on panda. Maybe omap5? | 22:50 |
| ericb2 | GrueMaster: indeed, it will probably not occur with Panda . Crossing the fingers | 22:51 |
| ericb2 | for omap5 .. in one, two years ? | 22:51 |
| * ericb2 hides | 22:51 | |
| infinity | Find me a mobile phone that needs SATA... | 22:51 |
| GrueMaster | Other than adding it to the USB bus, I wouldn't get your hopes up on panda. | 22:51 |
| infinity | (Panda's essentially a phone dev platform) | 22:51 |
| ericb2 | infinity: I meant more a multimedia one ( double hdmi .. ) | 22:52 |
| GrueMaster | Panda is the same hardware as the Droid 3. | 22:52 |
| ericb2 | + lot of decoders inside. Looks lke a mix of best technos, for hackers and like | 22:52 |
| GrueMaster | Other than a few NAS systems out there, I don't know of any mainstream arm based products that also have sata. | 22:53 |
| infinity | There are tons. | 22:53 |
| infinity | Mostly set-top boxes, PVRs and the like. | 22:53 |
| GrueMaster | Mainstream? | 22:53 |
| infinity | Well, depends on how you define "mainstream". | 22:53 |
| TheSeven | MrCurious_, ericb2: USB is still way faster than SD | 22:54 |
| ericb2 | maybe nfs, as I told previously | 22:54 |
| GrueMaster | Most of those are PPC based afaik. | 22:54 |
| infinity | Most people get them bundled with cable service and such, but that's pretty "mainstram", you just don't go comparison shopping. | 22:54 |
| * GrueMaster owned a tivo and owns an HD DVR. | 22:54 | |
| * ericb2 got a powerbook in the room. bought in october 2005 or so | 22:54 | |
| ericb2 | works well | 22:55 |
| TheSeven | davidm: So it doesn't make sense to do further random testing and throwing results at the bug from my side? | 22:55 |
| * davidm still owns 2 working tivo series I and has 4 for spare parts | 22:55 | |
| ericb2 | oops, it's late, and I need to sleep a bit | 22:56 |
| davidm | Any valid testing might help, the bug is not isolated as yet | 22:56 |
| ericb2 | good night all | 22:56 |
| infinity | Apparently the PVR in my house is MIPS. | 22:57 |
| davidm | OK I'm off, I'll look at the back scroll later | 22:57 |
| ericb2 | infinity: got a gdium too :) | 22:57 |
| * ericb2 gone for true | 22:58 | |
| MrCurious_ | theseven: i use a ssd on usb, it makes ubuntu on panda tolerable :D | 23:02 |
| GrueMaster | MrCurious_: Try booting with nosmp and checking your IO performance. | 23:03 |
| TheSeven | MrCurious_: a thumbdrive would do as well | 23:07 |
| MrCurious_ | yeah | 23:16 |
| MrCurious_ | gruemaster: is that a opt for boot.scr? | 23:16 |
| GrueMaster | Yes. Add to the kernel cmdline. | 23:17 |
| MrCurious_ | is that going to kick the speed up? | 23:17 |
| MrCurious_ | but at a cost | 23:17 |
| GrueMaster | IO speed should be 3-4x but no SMP. | 23:17 |
| MrCurious_ | thats a strange tradeoff | 23:18 |
| MrCurious_ | counterintuitive | 23:18 |
| infinity | See above about spinlocks. | 23:18 |
| MrCurious_ | doubt spinlocks are broken, more like not optimized | 23:22 |
