| RobotGuy | Is there a way to get gcc 4.3 instead of 4.4 or 4.5? | 00:21 |
|---|---|---|
| RobotGuy | Is there a way I can tell rootstock to use gcc 4.3 instead of the later compilers? | 01:20 |
| rcn-ee | RobotGuy, are building stuff in roostock? otherwise select the 'gcc-4.3' package.. | 01:21 |
| RobotGuy | Yes, rootstock. I tried selecting gcc-4.3 but it doesn't seem to work. | 01:22 |
| rcn-ee | what do you mean it doesn't work? | 01:22 |
| RobotGuy | It still takes gcc 4.5 | 01:23 |
| RobotGuy | Or maybe it is 4.4, but not 4.3 | 01:23 |
| rcn-ee | when you call "gcc" in your image? gcc-default does that, either call "gcc-4.3" in your build script or change the setting in ubuntu.. | 01:23 |
| RobotGuy | I already told you I did that - selected "gcc-4.3" and it doesn't get me gcc 4.3 | 01:24 |
| rcn-ee | which distro? | 01:24 |
| RobotGuy | Ubuntu built with rootstock. | 01:25 |
| rcn-ee | RobotGuy, lucid/maverick? | 01:25 |
| RobotGuy | 10.10 Maverick | 01:25 |
| rcn-ee | it exists.. http://packages.ubuntu.com/maverick/gcc-4.3 package name "gcc-4.3" to your seed or "sudo apt-get install gcc-4.3" will instal it later.. | 01:26 |
| rcn-ee | but you 'unverise' enabled in rootstock.. | 01:26 |
| RobotGuy | I haven't done anything to rootstock - it is as it was installed. | 01:27 |
| rcn-ee | RobotGuy, so you added "gcc-4.3" to the seed and you say it doesn't work.. what doesn't work about it in your mind? | 01:28 |
| RobotGuy | I still see it pulling "gcc-4.5-base" | 01:40 |
| cwillu_at_work | RobotGuy, adding a package won't generally remove a package | 01:40 |
| cwillu_at_work | I believe there's an option to remove a package from the seed though | 01:40 |
| cwillu_at_work | (not sure, my rootstock is thoroughly hacked up, and I promised to write up my changes and upstream them some day :p) | 01:40 |
| RobotGuy | This is not intuitive at all. | 01:41 |
| rcn-ee | it's not really suppost to be.. just a quick way to make a base image... add the extra's later... | 01:41 |
| cwillu_at_work | RobotGuy, adding a package shouldn't remove packages. | 01:41 |
| RobotGuy | I want to replace a package. | 01:42 |
| cwillu_at_work | RobotGuy, if you want to replace a desk, how do you go about doing that? | 01:42 |
| RobotGuy | There is also apparently a problem with Ubuntu recognizing the ethernet on the Beagle-xM. | 01:43 |
| ScottK | RobotGuy: Having GCC 4.5 installed doesn't preclude you from building with 4.3 if it's also installed. 4.5 is part of the build-essential metapackage for 10.10 so it's assume to be there for building. | 01:43 |
| cwillu_at_work | unrelated :p | 01:43 |
| RobotGuy | cwillu_at_work: I'm not a first grader | 01:43 |
| rcn-ee | RobotGuy, pulling in 'gcc-4.5-base' happens.. you want "gcc-4.3" that depends on "libc6" which depends on "libgcc1" which depends on "gcc-4.5-base" ... ;) | 01:44 |
| rcn-ee | just a big circle.. | 01:44 |
| cwillu_at_work | RobotGuy, I didn't say that you were, and supplying an analogous example was recognition of intelligence | 01:44 |
| cwillu_at_work | there's that bit, too :) | 01:45 |
| RobotGuy | gcc 4.4 and 4.5 just seem to be big problems. | 01:45 |
| cwillu_at_work | what problems are you seeing? | 01:46 |
| RobotGuy | Internal compiler errors | 01:46 |
| cwillu_at_work | I suspect you're doing something wrong somewhere; what's your build setup like? | 01:46 |
| RobotGuy | I'm just trying to build a kernel. | 01:47 |
| cwillu_at_work | how? | 01:47 |
| cwillu_at_work | native builds? cross compiling? qemu? | 01:47 |
| RobotGuy | On beagleboard | 01:47 |
| cwillu_at_work | c4? | 01:48 |
| RobotGuy | No, Beagle-xM A2 | 01:48 |
| cwillu_at_work | okay; xm is a different beast from the other beagles | 01:49 |
| cwillu_at_work | and one which I don't own :( | 01:49 |
| * cwillu_at_work accepts donations :p | 01:49 | |
| cwillu_at_work | which distro and version? | 01:50 |
| cwillu_at_work | any oddities on how things were installed? | 01:50 |
| cwillu_at_work | hell, is the xm even stable in general? :) | 01:50 |
| RobotGuy | Ubuntu 10.10 built from rootstock. | 01:51 |
| rcn-ee | the most important thing is 'what' kernel and 'what' clockspeed only angstrom's can handle the full 1Ghz, mine limited to 800mhz otherwise it's unstable.. | 01:52 |
| cwillu_at_work | not even rcn-ee is perfect :) | 01:53 |
| rcn-ee | specially with zippy's... i think it esd'd it today, everything but the ks8851 works on it.. | 01:53 |
| RobotGuy | It's a 2.6.35 kernel. | 01:53 |
| rcn-ee | ubuntu's? | 01:54 |
| cwillu_at_work | RobotGuy, the included patches matter | 01:54 |
| RobotGuy | Yes | 01:54 |
| RobotGuy | I don't have any idea what patches - it comes with linux-image-omap | 01:54 |
| rcn-ee | it should work, never tested itmy self.. can you "dmesg | grep mpurate|core" | 01:54 |
| RobotGuy | rcn-ee: I haven't changed the clock rate | 01:55 |
| rcn-ee | then it should be the default 500ish.. no idea why your board is iceing in gcc, it shouldn't.. | 01:55 |
| RobotGuy | 500? Mine says 800 | 01:56 |
| rcn-ee | oh great... | 01:56 |
| rcn-ee | your running an image with my install script with ubuntu's kernel and pushing 800... no idea if that's stable, nor have tested it.. | 01:56 |
| RobotGuy | I didn't change anything. | 01:57 |
| rcn-ee | can you pastebin the boot.scr in the fatfs? | 01:57 |
| RobotGuy | You're telling me that to use Ubuntu, I have to run at half the speed of my board? | 01:58 |
| cwillu_at_work | rcn-ee, your kernel brings up the network on that, no? | 01:58 |
| RobotGuy | I've never been able to get networking to work. | 01:59 |
| cwillu_at_work | RobotGuy, you're not using rcn's kernel | 01:59 |
| rcn-ee | it should, it does on all my xM boards.. | 01:59 |
| cwillu_at_work | RobotGuy, rerun rootstock with one of his kernel's (which iirc is how rootstock is intended to be used anyway) | 02:00 |
| rcn-ee | RobotGuy, the ubuntu guys didn't get a working xM board till a week before freeze... my timelines are much more relaxed.. 'aka oh crap, lets upload a fix now' | 02:00 |
| RobotGuy | You're not listening to me. | 02:00 |
| cwillu_at_work | RobotGuy, no, you're not listening to us. | 02:00 |
| RobotGuy | I have not changed anything in rootstock. | 02:00 |
| cwillu_at_work | you're doing things wrong, and expecting it not to matter. | 02:00 |
| RobotGuy | How am I doing things wrong? | 02:01 |
| RobotGuy | What am I doing wrong? | 02:02 |
| cwillu_at_work | <rcn-ee> then it should be the default 500ish.. no idea why your board is iceing in gcc, it shouldn't.. | 02:02 |
| cwillu_at_work | because | 02:02 |
| cwillu_at_work | <rcn-ee> RobotGuy, the ubuntu guys didn't get a working xM board till a week before freeze | 02:02 |
| cwillu_at_work | therefore | 02:02 |
| cwillu_at_work | <rcn-ee> the most important thing is 'what' kernel and 'what' clockspeed only angstrom's can handle the full 1Ghz, mine limited to 800mhz otherwise it's unstable.. | 02:02 |
| RobotGuy | We seem to be going round in circles and I am getting quite dizzy. | 02:03 |
| cwillu_at_work | :) | 02:03 |
| cwillu_at_work | RobotGuy, if you want to use rootstock, and you want to run at 800mhz, then you need to supply rcn's kernel. You can probably do this without remaking the image, although it's a bit finicky | 02:03 |
| cwillu_at_work | If you use rcn's kernel, the network will also Just Work. | 02:04 |
| RobotGuy | I keep telling you people that I did not change the clockrate. | 02:04 |
| cwillu_at_work | (incidently, I can has preempt_voluntary kernel now rcn-ee?) :) | 02:04 |
| cwillu_at_work | RobotGuy, and we keep telling you that the ubuntu kernel isn't stable at the default clockrate | 02:04 |
| cwillu_at_work | there are required patches which weren't available when ubuntu's kernel was frozen for release | 02:05 |
| cwillu_at_work | only angstrom's kernel has all the patches (because that's where they get developed for the most part) | 02:05 |
| cwillu_at_work | eventually everybody will have them, but the hardware only came out a couple months ago. | 02:05 |
| rcn-ee | RobotGuy, if it's running 800Mhz, more then likely you used my "setup_sdcard.sh" script.. a "cat boot.scr | pastebinit" would prove it.. | 02:05 |
| RobotGuy | Obviously, trying to use Ubuntu was not a good idea for me. Bummer. I thought it would be better. | 02:05 |
| rcn-ee | it's that boot.scr script that changes it to 800 | 02:06 |
| cwillu_at_work | RobotGuy, don't be that way. Every mainline distro will be weird at this point. | 02:06 |
| cwillu_at_work | er, major | 02:06 |
| cwillu_at_work | You need to substitute one piece, and everything will work fine. | 02:06 |
| RobotGuy | What piece? | 02:07 |
| cwillu_at_work | rcn-ee, 2.6.36-dl13? | 02:07 |
| cwillu_at_work | http://rcn-ee.net/deb/maverick/v2.6.36-dl3/ | 02:07 |
| cwillu_at_work | RobotGuy, as it stands, you're mixing and matching pieces which assume you're doing it this way anyway | 02:07 |
| cwillu_at_work | it's an honest mistake, especially common with new hardware | 02:08 |
| cwillu_at_work | but it's not our fault any more than it's your fault. | 02:08 |
| RobotGuy | This is not making sense to me. :( | 02:08 |
| cwillu_at_work | RobotGuy, can you run the command rcn-ee gave you please? | 02:09 |
| RobotGuy | I need to be able to use the full speed of my Beagle-xM. If Ubuntu can't do that, then I can't use Ubuntu right now. | 02:09 |
| cwillu_at_work | pastebinit boot.scr | 02:09 |
| rcn-ee | RobotGuy, 'full' speed is only one option right now and it's angstrom, and it's on TI's 2.6.32 kernel.. The rest of us will have that hopefully in 2.6.37... | 02:10 |
| cwillu_at_work | RobotGuy, so you run a different kernel, which is already packaged at the address I gave you above. | 02:10 |
| RobotGuy | Which is it? Ubuntu can or can not run at full speed on a Beagle-xM? | 02:11 |
| cwillu_at_work | none of this has anything to do with networking, nor gcc-4.4/4.5 | 02:11 |
| cwillu_at_work | RobotGuy, ubuntu with rcn's kernel will run at 800mhz right now, and will run at 1ghz in january | 02:11 |
| RobotGuy | OK, that answers my question. I'll try Ubuntu again in January or Feb then. | 02:12 |
| RobotGuy | We can't hold up development that long. | 02:12 |
| cwillu_at_work | how does this hold up development? | 02:12 |
| rcn-ee | i was thinking next week.. ;) but git rebase of dvfs-pm was a huge mess. ;) | 02:12 |
| cwillu_at_work | rcn-ee, I was being conservative :p | 02:12 |
| RobotGuy | I told you - we need the full speed of the Beagle-xM now. | 02:12 |
| cwillu_at_work | how could you possibly know that? | 02:13 |
| rcn-ee | yeah stable for everyone else.. january.. ;) | 02:13 |
| rcn-ee | cwillu_at_work, does btrfs seem to bog down for you in git tree's? | 02:13 |
| RobotGuy | The nature of our project requires top speed. | 02:13 |
| cwillu_at_work | rcn-ee, heh, complicated question :p | 02:13 |
| cwillu_at_work | RobotGuy, this is probably a good time to mention that ti's hardware isn't intended for prototyping of actual products, or actual deployment | 02:14 |
| cwillu_at_work | er, the beagle's | 02:14 |
| rcn-ee | git checkout's seem to bog when going from Head to a older branch... i think i really need to enable the new 2.6.37 mount opiton.. | 02:14 |
| rcn-ee | RobotGuy, optomize more.. ;) | 02:14 |
| RobotGuy | I am well aware of that. We are developing, not producing. | 02:15 |
| cwillu_at_work | RobotGuy, if you're developing, then the product speed doesn't matter. multiply your benchmarks by 20% :p | 02:15 |
| RobotGuy | Speed does matter, but I am not here to argue. | 02:15 |
| cwillu_at_work | rcn-ee, you mean the git commands themselves? | 02:16 |
| rcn-ee | yeah, like a git fetch; git checkout HEAD; git checkout an old branch.. | 02:16 |
| cwillu_at_work | I haven't noticed anything, but | 02:17 |
| cwillu_at_work | might try running a defrag | 02:17 |
| cwillu_at_work | which mount options are you using currently? (or have used in the past, some are sticky) | 02:17 |
| cwillu_at_work | (note that defrag operates on specific folders and files; it's not enough to specify the root) | 02:17 |
| rcn-ee | could be, i build a lot of kernels on this machine.. or one of the two enabled but not 'advertised' cores is failing on this fake x4.. | 02:17 |
| rcn-ee | just 'btrfs defaults' in /etc/fstab... | 02:18 |
| cwillu_at_work | nochecksum,nocow might help matters, at least for things like builds and so forth | 02:18 |
| cwillu_at_work | you'd have to do a separate btrfs filesystem though, as those currently can't be set separately on subvolumes | 02:18 |
| rcn-ee | okay, i'll try that.. | 02:19 |
| cwillu_at_work | bah, he left | 02:19 |
| cwillu_at_work | I was going to mention that pandaboard might be more useful | 02:19 |
| rcn-ee | he's been stuck on that issue since like tuesday night... | 02:20 |
| cwillu_at_work | yeah, I'm pretty sure he's been told 3 different build approaches that would give him the end result he wants | 02:20 |
| cwillu_at_work | and he's consistently refused to follow any one of them :p | 02:20 |
| rcn-ee | yeap, it's a receipe for disaster.. | 02:21 |
| cwillu_at_work | I feel like I was getting overly crotchety, but... | 02:21 |
| cwillu_at_work | anyways | 02:22 |
| cwillu_at_work | rcn-ee, so, I see you're at home now :) | 02:22 |
| rcn-ee | yeah... 8ish to 5ish.. ;) | 02:23 |
| cwillu_at_work | do you know what that means? :) | 02:23 |
| rcn-ee | i can never be found... | 02:23 |
| cwillu_at_work | hint: it involves a kernel :) | 02:23 |
| rcn-ee | cwillu_at_work, here they are: http://rcn-ee.homeip.net:81/testing/2.6.36-something/ (forgot what i enabled, but it was that one thing) | 02:24 |
| cwillu_at_work | \o/ | 02:25 |
| cwillu_at_work | thanks | 02:25 |
| cwillu_at_work | preempt_voluntary I believe | 02:25 |
| rcn-ee | yeah that.. i knew it was 'something' | 02:26 |
| cwillu_at_work | rcn-ee, without ck? | 02:28 |
| rcn-ee | yeah, without ck... | 02:28 |
| enth | Does ubuntu ARM work on StrongARM / PXA27xx processors? | 02:38 |
| rcn-ee | enth, not really, that stuff is too old... debian or angstrom is really your only options... | 02:39 |
| enth | \: Ok thanks. | 02:42 |
| cwillu_at_work | download complete | 02:44 |
| rcn-ee | yay i get my bandwidth back. ;) | 02:44 |
| cwillu_at_work | I was going to apologize for your untimely responses :) | 02:45 |
| rcn-ee | i'm just drinking a beer, waiting for stuff to build.. ;) | 02:45 |
| cwillu_at_work | while you wait: http://www.fanfiction.net/s/4068153/1/ | 02:46 |
| cwillu_at_work | :p | 02:46 |
| cwillu_at_work | booting | 02:48 |
| cwillu_at_work | (with the network plugged in, no less!) | 02:48 |
| cwillu_at_work | that was quick | 02:49 |
| rcn-ee | quick hard lock? | 02:49 |
| cwillu_at_work | yep | 02:50 |
| cwillu_at_work | and again | 02:52 |
| cwillu_at_work | okay, it's not my full preempt sillyness triggering this then | 02:53 |
| cwillu_at_work | rcn-ee, incidently, you mentioned that ks8851 was troublesome at 1ghz; it isn't troublesome in the same way is it? | 02:53 |
| rcn-ee | no, it's the omap part, needs a voltage bump to the next level thru smartreflex | 02:54 |
| cwillu_at_work | okay | 02:55 |
| cwillu_at_work | tempted to get one just to reproduce this :p | 02:55 |

| sveinse | I understand that a lot of you is running Ubuntu off a (micro) SD card, right? | 12:56 |
| sveinse | Yesterday I purchased a new Class 4 Kingston 8GB micro SD. However, this card is something of the slowest I've ever seen running Ubuntu on | 12:57 |
| sveinse | My old 2GB Trancend (which was bundled with a HTC phone) is *much* faster | 12:58 |
| sveinse | Have any of you experienced differences and difficulties in respect of memory cards? | 12:58 |
| sveinse | I.e. how can I find one with is fast?.. | 12:58 |
| ogra_ac | take class 10 | 13:15 |
| sveinse | But the class is related to read/write speeds. | 13:18 |
| sveinse | I did a bonnie++ comparison between the two cards. Suprisingly the read/write rates were comparible | 13:18 |
| sveinse | However the latency on IO were 4-5 times higher on the newest card. Example. latency on random create read were 3174 us on the new, while 184 us on the old | 13:20 |
| sveinse | So obviously there is some other parameter here which is not covered by the class concept | 13:21 |
| ogra_ac | well, i get nearly USB results with class 10 cards here | 13:24 |
| sveinse | Yeah, I'll see if I can get my hands on one. Which brand? | 13:24 |
| ogra_ac | i had good results with panasonic gold cards | 13:25 |
| sveinse | Panasonic. Interesting | 13:25 |
| sveinse | I not surprised though. I've had previous experiences that the off-the-radio-shack-shelf cards can be cheap (i.e. poor quality) | 13:27 |

| Neko__ | hey guys, anyone have any official view or a wiki or something on how to version packages based on git repos? | 17:06 |
| Neko__ | mainly for kernel packages | 17:10 |
| Neko__ | git commit ids aren't debian standards compliant so I can't make the debian --revision thing the tag | 17:10 |
| === Neko__ is now known as Neko | ||
| ScottK | Neko: Debian package versioning has to be monotonically increasing so using git ids is out. I usually use the date, i.e. 2010113, instead. | 18:18 |
| Neko | but some packages have stuff like +gitblahblah or ~gitsomething or ~something at least | 18:18 |
| Neko | I never found anything which tells me what these really mean or what is recommended | 18:18 |
| Neko | now I check I can't even find a package with that versioning but I know there are some :D | 18:18 |
| ScottK | I'm familiar with it. | 18:22 |
| ScottK | In Debian versionin "~" is somewhat magical in that it's less than anything else. | 18:22 |
| ScottK | So 1.0~git20101113 is less than 1.0. You'd use this to indicate some pre-1.0 snapshot. | 18:23 |
| ScottK | If you're packaging something that's a bit beyond 1.0, you'd use 1.0+git20101113 since that's higher than 1.0. | 18:23 |
| ScottK | Neko: Does that clarify it? | 18:24 |
| Neko | oh-ho! I see :) | 18:25 |
