| mkopack | Hey gang… So I got the 11.10 Server prebuilt image installed and working on my panda board ES. Wifi is working fine. I installed LXDE for a desktop. However, sound doesn't seem to work. Do I need to install the OMAP driver package to get that working? | 01:54 |
|---|---|---|
| twb | mkopack: have you checked mixer levels? | 01:55 |
| mkopack | Yeah, volume control shows not muted, vol maxed. | 01:56 |
| mkopack | For testing I downloaded a free MP3 file, and am trying to run it through the media player in LXDE, just not getting anything out. | 01:56 |
| mkopack | It's not the end of the world, I can live without sound, I'm just wondering if there's other issues (like GFX ) that I might also be missing | 01:57 |
| twb | mkopack: you checked all channels in alsamixer | 01:57 |
| twb | ? | 01:57 |
| twb | Also better to test with raw data (e.g. PCM) with aplay | 01:57 |
| twb | I don't know anything about the specific unit you're on, that's just the most obvious first thing to check | 01:58 |
| mkopack | Hmm, ok, I'll give that a try... | 01:58 |
| mkopack | tnx | 01:58 |
| infinity | mkopack: Sound on the PandaES won't work out of the box in oneiric, we only added the UCM fixes for it in precise. | 01:59 |
| mkopack | Crap. I'm in the middle of doing the ROS install so I'm going to have to wait to install alsamixer | 01:59 |
| mkopack | ah, k | 01:59 |
| mkopack | thanks | 01:59 |
| mkopack | I'll probably move up to 12.04 once the actual release is out. but in the mean time I'm getting my teeth cut with this 11.10 | 02:00 |
| infinity | I'd really recommend just trying precise now. We just released Beta-2, which is pretty close to where we expect final to be. | 02:00 |
| infinity | And we'd appreciate bug reports to make it better. :) | 02:00 |
| infinity | (Plus, your PandaES will run both faster and cooler with the precise kernel...) | 02:01 |
| mkopack | I'll give that a try over the weekend.. Luckily I have a couple 16 GB SD cards to play with | 02:12 |
| mkopack | I only get a couple hours at home at night to really work on this ting | 02:13 |
| mkopack | Ahh, a watched ROS never compiles ;) .... | 02:25 |
| mkopack | (actually it's going surprisingly well, I must say) | 02:26 |
| plugwash | is there any equivilent of packages.ubuntu.com for ubuntu armel and armhf? | 06:50 |
| === zyga is now known as zyga-afk | ||
| janimo` | GrueMaster, feel free to remove https://code.launchpad.net/~gruemaster/flash-kernel/bug-961174/+merge/98874 if the corresponding bug is wontfix | 09:25 |
| janimo` | it showed up in the sponsoring queue and I almost considered uploading it before seeing in tiny green letters that the bug is wontfi | 09:25 |
| janimo` | LP UI is not the best | 09:25 |
| janimo` | tiny gray letters that is | 09:25 |
| mythos | plugwash, you man a website to lookup packages, search for/in packages, etc? no | 10:04 |

| traisen | What is the minimum memory that will support ubuntu arm version? | 14:03 |
| === Quintasan_ is now known as Quintasan | ||
| xranby | traisen: it depend if you want to run the full desktop | 14:04 |
| xranby | traisen: a regular unity-2d session work ok using 512mb of ram | 14:05 |
| xranby | the system then consume around 200mb on startup | 14:05 |
| xranby | you can of course use 256mb of ram + some swap | 14:05 |
| xranby | that will allow you to run most applications | 14:05 |
| xranby | if you run headless like ubuntu-core | 14:06 |
| xranby | then you should be able to make it with 64mb of ra | 14:06 |
| xranby | m | 14:06 |
| traisen | Thanks, Do you know if anyone has tried it on the Lego Mindstorms NXT ? 256kbyte FLASH- und 64kbyte RAM-Speicher | 14:08 |
| xranby | do you know which arm cpu it are using? | 14:10 |
| traisen | Atmel | 14:10 |
| xranby | ok, do you know the variant? | 14:10 |
| traisen | (or do you need more info) | 14:10 |
| xranby | i need more info | 14:10 |
| xranby | atmel make amny cpus | 14:10 |
| xranby | many | 14:10 |

| xranby | off hand i can tell you ubuntu will not boot on this device | 14:11 |
| traisen | Just a minute | 14:11 |
| xranby | but you can most likely write code for it using the ubuntu arm gcc | 14:11 |
| xranby | if you have a way to upload code to this mindstorm device | 14:11 |
| traisen | Currently using gnu tool chain, but ubuntu is better known then eCos | 14:12 |
| traisen | But wouldn't the o/s have to be a favor of ubuntu, even if a minimal version? | 14:13 |
| traisen | AT91SAM7S256 | 14:15 |
| janimo` | traisen, ubuntu hardly fits on a device with 1000 times as much memory | 14:15 |
| xranby | traisen: FOR THIS KIND OF DEVICE I RECOMMEND OPENEMBEDDED OR SCRATCHBOX | 14:15 |
| janimo` | maybe the bootloader used on typical ubuntu arm hw would fit on the mindstorm :) | 14:15 |
| xranby | OOPS | 14:16 |
| xranby | damn capslock | 14:16 |
| traisen | No desktop needed | 14:16 |
| xranby | traisen: the problem are that a regular liux kernel require more than 256kb of flash | 14:16 |
| janimo` | traisen, ecos should be pretty good for it for the type of apps you'd probably run on it | 14:16 |
| xranby | traisen: for a minimal embedded linux system you need at least 4mb of flash | 14:17 |
| xranby | to store the kernel and a minimal root filesystem | 14:17 |
| xranby | and more ram | 14:17 |
| xranby | you can compare this lego device with your usb mousepointer | 14:18 |
| xranby | the usb mouse probably have more flash | 14:18 |
| xranby | if it are flash based | 14:18 |
| traisen | MB not Kb :) eCos is working... thanks for mentioning other options, so I have something to compare against. | 14:23 |
| janimo` | hackish patch to get mongodb run its smoketest completed, now to clean up maybe and backport to Ubuntu's stable version hopefully before 12.04 | 15:35 |
| * janimo` resists being sidetracked into debugging mongo for ppc on the porter machine. | 15:36 | |
| infinity | janimo`: Go for it, get sidetracked. | 16:08 |
| infinity | janimo`: I thought mongo was heavily x86-centric. Just how large is your patch? | 16:08 |
| infinity | (Or maybe I'm confusing it with another package that had a "don't bother trying to port this" note...) | 16:10 |
| infinity | Ahh, there it is. | 16:10 |
| infinity | The mongodb server depends on both little-endianness and unaligned memory | 16:11 |
| infinity | access, which I believe means it can only work on i386 and amd64. We believe | 16:11 |
| infinity | that the mongodb will be useful even it is not available for all Debian | 16:11 |
| infinity | supported platforms. | 16:11 |
| infinity | janimo`: Is the above no longer true? | 16:11 |
| tedg | Howdy folks. | 16:48 |
| tedg | We've got a test that's using callgrind, but it's failing to link on ARM. | 16:48 |
| tedg | Could someone take a look? It seems like callgrind isn't built right on ARM. | 16:48 |
| tedg | https://launchpadlibrarian.net/98928961/buildlog_ubuntu-precise-armhf.libdbusmenu_0.5.96-0ubuntu1_FAILEDTOBUILD.txt.gz | 16:49 |
| infinity | tedg: You didn't get the memo that ARM is everyone's problem/responsibility now? ;) | 16:50 |
| tedg | infinity, yes, that's why I'm helping -- by finding bugs :-) | 16:51 |
| infinity | *smirk* | 16:51 |
| infinity | janimo`: Know anything about valgrind on ARM? | 16:51 |
| plugwash | <mythos> plugwash, you man a website to lookup packages, search for/in packages, etc? no <-- yes packages.ubuntu.com lets me search for/in packages on the official ubuntu architectures I was wondering if there was an equivilent for ubuntu armel and armhf | 17:54 |
| mythos | plugwash, answer is no | 17:55 |
| plugwash | ok | 17:55 |
| mythos | the easiest way is a chroot and apt-file/apt-cache | 17:56 |
| infinity | plugwash: packages.u.c is maintained by frank@lichtenheld.de, feel free to bug him about adding ports. ;) | 18:29 |
| infinity | plugwash: Of course, there's also Contents-$arch on the mirrors. | 18:31 |
| janimo` | infinity, mongodb is indeed x86 centric but not by design, they just did not care for portability much | 18:52 |
| janimo` | and there are not many places where it needs changing but my chjanges are not the most elegant | 18:53 |
| janimo` | so unaligned double and atomic int accesses cause traps and it is mostlt about finding and fixing those places | 18:53 |
| janimo` | infinity, I had a fire-and-forget ARM patch sent to valgrind once but not much knowledge more besides that | 18:54 |
| janimo` | infinity, as for the size of the mongo patch it is mongoarm.diff here, most recent comments | 19:01 |
| janimo` | that is against master which built and ran fine, applying the same to the 2.0 branch still crashes so I have some more digging to do | 19:01 |
| janimo` | infinity, regarding ppc, I probably need to debug it there too, after the single patch that is needed on ARM too (make char signed explicitely in one place) | 19:01 |
| janimo` | it still crashed and the build for some reason did not have debug symbols so gdb did not help me | 19:02 |
| janimo` | which is strange as the same default build on x86 and arm has debug symbols | 19:02 |
| janimo` | anyway I probably need to look at it some more, probably my last chance to play with ppc if I am reading my crystall ball correctly | 19:03 |
| janimo` | also my first time working on a ppc :) | 19:03 |
| infinity | Heh. | 19:05 |
| infinity | If you need access to a PPC machine to play, let me know. | 19:05 |
| infinity | Although, I guess you have access to the porter in the DC too. | 19:05 |
| infinity | But yeah, the claims that it's endian-specific don't bode well for PPC. | 19:06 |
| infinity | Maybe that was overstated and/or incorrect. | 19:06 |
| infinity | If you can make it both endian and alignment clean, I'm sure the Debian maintainer would love you forever. | 19:06 |
| janimo` | infinity, yes, it is the porter that I tried building mongo today and which crashed even after one fix which was also needed for arm | 19:20 |
| janimo` | infinity, ah indeed, it is probably endian specific too, but that luckily did not affect arm | 19:20 |
| janimo` | there was a mongo-nonx86 branch against 1.8 last year but it is very messy and the author no longer maintains it | 19:21 |
| janimo` | it had fixes for all sorts including arm | 19:21 |
| janimo` | infinity, I already had a few exchanges with antonin, pushin all but our upstart script to him to lessen delta | 19:22 |
| janimo` | and was surprised to find out that debian packages (or the system) can break if upstart scripts are installed | 19:22 |
| janimo` | because of some yet undeployed dpkg fix | 19:22 |
| janimo` | ah so that's wre my diskspace went | 19:29 |
| * janimo` discovers a 21Gb log from Gnash | 19:29 | |
| highvoltage | wow | 19:31 |
| janimo` | highvoltage, possibly the effects of always open browser+gnash installed+infrequent reboots. Anyway, removed | 19:39 |
| highvoltage | I use the #rmrf tag on identica/twitter for things like that. like http://identi.ca/notice/50474501 and http://identi.ca/notice/71778992 :) | 19:41 |
| Mephisto__ | Hello people! I'm looking at a kernel config (versatile) for a recent kernel, I cannot seem to make em work (a part from the 2.6.22 which doesn't support ext4), any help is appreciated | 20:58 |
| infinity | Mephisto__: Why versatile? It's long obsolete. | 21:25 |
| infinity | Mephisto__: Surely, you want vexpress? | 21:25 |
| Mephisto__ | well i'm a total newbie to this here's the system I'm trying to "emulate" | 21:27 |
| Mephisto__ | http://www.sealevel.com/store/relio-r9-arm9-embedded-risc-computer.html | 21:27 |
| infinity | Oh. Then you're almost certainly in the wrong channel, as Ubuntu won't run on that system (nor an emulated version of it). | 21:29 |
| infinity | ARM9 is ARMv5, Ubuntu only supports ARMv7. | 21:30 |
| infinity | Actually, that might even be v4t. | 21:31 |
| infinity | Anyhow, you might want to try Debian, and they do have versatile kernels packaged as well. | 21:31 |
| Mephisto__ | so it's versatile right? | 21:31 |
| infinity | Erm. That system isn't the same thing as a versatile board from ARM, no. | 21:33 |
| infinity | But they're perhaps vaguely similar product families. | 21:33 |
| infinity | In either case, Ubuntu won't run on either one (old ARM versatile boards, the qemu versatile target, nor this machine you linked). | 21:33 |
| Mephisto__ | I see | 21:34 |
| Mephisto__ | thanks a lot for valuable informations and your time sir | 21:34 |
| infinity | No problem. | 21:34 |
