**** BEGIN LOGGING AT Wed Nov 24 02:59:59 2010 Nov 24 03:43:32 Hey all. Nov 24 03:43:43 Anyone have experience writing gigabit ethernet drivers? Nov 24 04:05:26 rbelem and Tscheesy: We need GCC fixed before anything happens on Qt/ARM for Natty. Nov 24 08:10:35 morning Nov 24 09:52:02 can anyone comment how to build kernel Headers for kernel source ? As I am using diff kernel tree than ubuntu and wanted to build pvr kernel modules Nov 24 09:54:12 make headers_install ARCH=arm INSTALL_HDR_PATH=/custom Nov 24 10:07:50 https://wiki.ubuntu.com/KernelGitGuide i think Nov 24 10:10:15 ah, no, its actually https://help.ubuntu.com/community/Kernel/Compile Nov 24 10:11:01 https://wiki.ubuntu.com/KernelTeam/GitKernelBuild might also help Nov 24 10:27:28 how to enable loopback device Nov 24 10:27:41 i cant see ifconfig -a lo interface Nov 24 10:32:40 ifconfig lo 127.0.0.1 up Nov 24 10:32:40 ? Nov 24 10:33:19 or "ifup lo" if you have ifupdown in your filesystem Nov 24 13:42:37 grmpf Nov 24 13:42:59 merging shadow provides to become really painful Nov 24 14:54:10 hello, i have some problems with the ubuntu 10.10 installation on the beagleboard xm with sd card. i tried the two methods on webpage to flash the sd card - https://wiki.ubuntu.com/ARM/OMAPMaverickInstall but i cant see the card on my linux pc after i put the files on the card. then i boot windows and format the card. any help what i did wrong ? Nov 24 15:04:57 GrueMaster: for https://wiki.ubuntu.com/ARM/OMAPMaverickInstall, should there be a "sync" after the zcat >device / dd of=device step? Nov 24 15:05:42 rOxx: are you sure you used the correct device node? what did you do to write the image to the card exactly? Nov 24 15:06:13 after the zcat and dd step i got no message Nov 24 15:06:42 i tried this two methods but nothing works Nov 24 15:07:07 rOxx: Try again, but after the zcat or dd step, type: Nov 24 15:07:07 sync Nov 24 15:07:19 ...and wait for the prompt to return Nov 24 15:07:29 Possibly not all of the data has hit the card? Nov 24 15:07:29 @dmart, yes im sure that is used the correct device. the name was mmcblk0p1 - a sd card with 8 gb Nov 24 15:07:45 thats definitely the wrong device name Nov 24 15:08:00 oh, yes, it must be the whole-device node: /dev/mmcblk0 Nov 24 15:08:11 right, the above is a partition name Nov 24 15:08:53 sorry is used /dev/mmcblk0p1 Nov 24 15:10:07 im back in few minutes. i want to test "sync" in console after flashing Nov 24 15:10:25 and im now in windows :;-( Nov 24 15:34:04 dmart: sync could help. I have a script that I use to zero then flash my SD card. The last step is for it to pop up a notification window letting me know it is done. Nov 24 15:35:12 writing to the device instead of the partition too Nov 24 15:35:13 And Idon't use the zcat method. I have found it to be less reliable than "gunzip ; dd" personally. Nov 24 15:35:38 huh ? Nov 24 15:35:45 there shouldnt be any difference Nov 24 15:35:55 there surely isnt techincally Nov 24 15:39:17 Not sure why. May be because with dd youcan write a block at a time, whereas the zcat method writes in byte mode. Nov 24 15:45:31 I have seen issues when using dd if I don't specify "bs=1024" or at least have"bs=" set to a sector or cluster divisable number. Nov 24 15:48:30 i´m back, but the sync command doenst help me Nov 24 15:50:14 here are the details Nov 24 15:50:29 bastian@bastian-Inspiron-1520:~/Downloads$ sudo dd bs=4M if=ubuntu-netbook-10.10-preinstalled-netbook-armel+omap.img of=/dev/mmcblk0p1 Nov 24 15:50:43 499+1 Datensätze ein Nov 24 15:50:50 499+1 Datensätze aus Nov 24 15:50:59 2094403584 Bytes (2,1 GB) kopiert, 228,692 s, 9,2 MB/s Nov 24 15:51:16 after that is used the sync command. after 1 second the prompt come back Nov 24 15:52:33 but after that i cant see the sd card Nov 24 15:53:50 gparted does not start after this process, when i disconnect the sd card gparted starts, the only way i find out to get access to the card was a windows system.... Nov 24 15:56:17 you are still writing to the wrong device with dd Nov 24 15:56:37 /dev/mmcblk0 is what you want Nov 24 15:56:49 *not* /dev/mmcblk0p1 Nov 24 15:56:53 thats a partition Nov 24 15:57:00 rOxx: Linux will not know about the new partition layout that was written to the card right away ... what happens after you remove and reinsert the card? Nov 24 15:57:19 dmart, he writes a partitioned image into a partition Nov 24 15:57:26 that wont work ;) Nov 24 15:57:46 that's also true Nov 24 15:57:56 dd ... of=/dev/mmcblk0 Nov 24 15:58:02 thx ogra, i will test without p1 Nov 24 15:58:02 (not ... /dev/mmcblk0p1) Nov 24 15:58:33 im back in few minutes. thanks for your help Nov 24 16:03:59 GrueMaster, did you put the suggestion for gunzip/dd on the install instructions ? Nov 24 16:04:49 yes, a while ago. Others were reporting on this channel that they were having issues, butthat the other method worked fine. Nov 24 16:05:20 can you please add a warning that his eats hilarious amounts of diskspace and should really only be used if zcat doesnt work Nov 24 16:05:46 with emphasis on *only* Nov 24 16:10:19 GrueMaster: I edited the wiki to add syncs; feel free to check it's OK Nov 24 16:11:31 Also, xM A3 / OMAP4 Blaze instructions talk about mounting partitions -- the user will need to remove/reinsert the card before this will work (or blockdev --rereadpt ) ... otherwise the kernel will use the old partition layout Nov 24 16:11:38 ...I think Nov 24 16:11:59 shouldnt Nov 24 16:12:19 ogra_ac: do you know why zcat doesn't work? What are the symptoms? Nov 24 16:12:39 dmart, i have never seen zcat fail Nov 24 16:12:46 on various systems Nov 24 16:12:57 dmart, GrueMaster claims its faulty Nov 24 16:13:10 Could it have been a forgot-to-sync problem maybe? Nov 24 16:13:47 Unless the kernel or SDIO layer is actually broken, there should _really_ be no difference between zcat and dd :O Nov 24 16:13:58 right Nov 24 16:14:05 thats why i think as well Nov 24 16:14:06 I have been able to make zcat fail reliably on some sd cards. Remember, I do this more often on a wider spread of card types & speeds. Nov 24 16:14:22 weird Nov 24 16:15:19 I can even get the dd method to fail if I don't specify "bs=" and have it divisable by 512. Nov 24 16:15:51 sounds like a kernel bug on your side Nov 24 16:16:09 Besides, my method also allows you to mount the image w/o writing it to an SD card. Nov 24 16:16:22 sure Nov 24 16:16:49 but it is one step more, complexifies the instructions and eats a lot of diskspace Nov 24 16:17:08 ogra_ac: I have seen this on Lucid & maverick now, both x86 & amd64 kernels. I have also seen this on babbage. Nov 24 16:17:15 (and its not a slow setp to gunzip 2G) Nov 24 16:18:10 * ogra_ac humms .... why oh why did i ever touch shadow Nov 24 16:18:47 that package went from looking like a sync to be an easy merge ... until all patches stopped applying Nov 24 16:19:26 If you feel there is a serious problem with my additional instructions (that people should use if zcat fails, according to the wiki as I added it), then by all means remove it. Nov 24 16:19:43 no, leave it in Nov 24 16:19:58 i just want them to be aware that it takes 10min extra and eats their disk Nov 24 16:20:25 10 minutes? Try 2 on my system with a Class 2 SD card. Nov 24 16:20:27 and should really make no difference Nov 24 16:20:41 i dont get why it does Nov 24 16:21:04 I agree that it *should not* make a difference. What I have seen in my daily testing tells me otherwise. Nov 24 16:21:18 i was talking about the extra gunzip above Nov 24 16:21:24 nothing to do with SD cards Nov 24 16:21:47 I'm talking about the whole procedure (including the gunzip). Nov 24 16:21:54 the dd as well as zcat should take the same time Nov 24 16:25:20 Read http://irclogs.ubuntu.com/2010/11/05/%23ubuntu-arm.html about 3/4 down. Nov 24 16:27:31 you mean the guy who had a hardcoded line in NAND to only load his kernel ? Nov 24 16:27:43 If it were just me having issues with zcat, I would do my own thing and move on. Nov 24 16:28:00 * ogra_ac doesnt see how that relates to zcat Nov 24 16:28:09 apart from you telling him that it does Nov 24 16:28:14 zcat didn't work for me, dd did perfectly Nov 24 16:28:33 without any further comment, yep Nov 24 16:29:39 Do I really needto pour through all the IRC logs to back myself up? I thought this was Linux, where there are multiple solutions to a single problem. Nov 24 16:29:50 well Nov 24 16:30:12 Again, if you have a problem with my alternate method being on the wiki, remove it. Nov 24 16:30:31 I'm done with this discussion, because it really isn't productive. Nov 24 16:30:45 i just asked you to add a warning ... Nov 24 16:30:52 why do you feel attacked Nov 24 16:31:36 it should simply be clear that this is just a fallback method and that it uses up a lot more resources and time Nov 24 16:32:08 I can't remember what happened when I used zcat but it didn't work as nice as dd, which have never failed me :) Nov 24 16:32:29 * ogra_ac would love to know how it failed Nov 24 16:32:53 given that there is no technical difference between the two Nov 24 16:33:35 i can imagine that something goes wrong due to sudo quoting or some such Nov 24 16:33:58 I could probably try it out again but not time atm for it Nov 24 16:34:10 but its weird that two techinally equal methods can have different results Nov 24 16:34:21 IIRC the problem was that it didn't boot properly Nov 24 16:34:29 yeah, i didnt mean to push you to it ;) Nov 24 16:34:41 weird Nov 24 16:34:42 pretty sure I did the command both with sudo and root Nov 24 16:34:52 but I could have done that wrong :) Nov 24 16:35:59 well, try it once if you need to anyway and note down whats wrong, i'm surely intrested in hearing about it Nov 24 16:36:20 btw, does your cloak indicate what i think ? :) Nov 24 16:37:05 (xbmc i mean) Nov 24 16:37:41 hehe, it does :) Nov 24 16:37:57 (if you think I'm a developer of the app?) Nov 24 16:38:20 have you seen https://blueprints.launchpad.net/ubuntu/+spec/multimedia-arm-n-set-top-box ? Nov 24 16:38:56 we're planning to provide a settop box install (no image but you should be easily able to build one with it) Nov 24 16:39:13 i was wondering why xbmc didnt make it into ubuntu yet Nov 24 16:39:24 Haven't seen, cool! Nov 24 16:39:38 Well I know one of our devs where with the media center thing for ubuntu Nov 24 16:39:56 seems there is a PPA but nobody ever uploaded it to the archive Nov 24 16:39:59 And reasons then was mostly license problems (and that it doesn't run without proper rendering) Nov 24 16:40:09 ah Nov 24 16:40:20 I think the biggest issue is that we have our own ffmpeg which is abit iffy Nov 24 16:40:21 well, rendering should be fine with the pandaboard Nov 24 16:40:27 we have drivers and codecs Nov 24 16:40:35 (gstreamer only though) Nov 24 16:40:42 ah Nov 24 16:40:55 yeah, ffmpeg is hard if its out of sync Nov 24 16:41:19 we are going to move it out of xbmc at some point, probably make it an addon. That way the only codec we provide out of the box is hw accel stuff which should be fine from a license point of view Nov 24 16:41:36 It is possible to build against external though, think angstrom does this Nov 24 16:41:48 debian do atleast, but its causing some problems at points Nov 24 16:41:49 ah, cool Nov 24 16:41:59 probably something to investigate for ricardo then Nov 24 16:42:28 A big goal for us with eden (next release) is to be perfectly ready for repo inclusion Nov 24 16:42:37 cool ! Nov 24 16:42:58 since camelot (and abit before) we have worked lots with fedora and such and should have most fixed Nov 24 16:43:11 before it was a mess with lots of internal libraries (xbox herritage :) ) Nov 24 16:43:17 ocra_ac and dmart thx for your help. now it works. mmcblk0 was the answer :-) Nov 24 16:43:18 heh, yeah Nov 24 16:43:31 rOxx, good to hear :) Nov 24 16:44:18 are you working with that blueprint ogra_ac? Nov 24 16:44:20 the config with der seriell ouput works and now im bootet ubuntu 10.10 on beagle. all works fine Nov 24 16:44:39 topfs2, nope, rsalveti-afk is Nov 24 16:44:45 (on vacation this week) Nov 24 16:45:18 topfs2, i'll only test BT remotes (for the fun of it) Nov 24 16:46:00 ah cool. Well I have a panda and trying to get xbmc to run awesome on it and considering we have openmax support already hopefully it will work out on panda also Nov 24 16:46:24 well, its all gstreamer currently Nov 24 16:46:33 does xbmc handle that ? Nov 24 16:47:05 (in ubuntu that is, i dont think anyone at TI has put work into OMX beyond gstreamer) Nov 24 16:47:39 nah we don't have gstreamer support but thats also something we have been investigating, atleast use the decode of it Nov 24 16:47:52 that would make it really easy Nov 24 16:47:55 but I really hope omx works properly outside it, otherwise I'm gonna ping them like crazy :) Nov 24 16:48:23 well, i know that they only focused on gst integration Nov 24 16:48:39 so you might have to work out solutions on your own Nov 24 16:48:54 personally I like gst but the timing and syncing of it when displaying isn't as good as it could but for decode its great Nov 24 16:49:25 i dont think i ever recorded with it Nov 24 16:49:56 I meant playing thogh :) Nov 24 16:50:48 hmm, i usually dont have issues with totem, but then thats a very simple app Nov 24 16:51:07 timing/syncing wise i mean Nov 24 16:51:48 I actually have quite a lot (on desktop) Nov 24 16:52:06 perhaps its just my computer Nov 24 16:52:12 on panda its fine for me Nov 24 17:06:32 speaking of BT remotes... does Playstation3 remote counts? Nov 24 17:06:50 hrw, sure Nov 24 17:07:06 i dont really expect issues with BT remotes Nov 24 17:07:18 it was just a good reason to buy one Nov 24 17:07:22 or more Nov 24 17:08:11 ogra_ac: ps3 remote is not BT HID but rather BT serial something Nov 24 17:08:26 i think there is an app for it in ubuntu Nov 24 17:09:22 ;D Nov 24 17:09:22 yeah we have a special thing for it for xbmc Nov 24 17:09:24 anyremote Nov 24 17:09:41 its to bad there isn't a great remote out there :) Nov 24 17:09:48 Remote control daemon for applications using Bluetooth, IrDA or WiFi Nov 24 17:09:55 that might do it Nov 24 17:10:45 * hrw -> out Nov 24 17:10:49 have a nice rest of day Nov 24 17:11:09 what bluetooth remote are you trying ogra_ac ? Nov 24 17:11:16 none yet Nov 24 17:11:24 i will have to buy a few soon Nov 24 17:53:07 ogra_ac: hi. any idea why package cpuburn from universe is not built for armel, and as such not available in the archive? the debian/control explicitely mentions armel as a target arch Nov 24 17:55:00 is there a way to cause dma_map_single to only choose from a very small region of memory? say 0xf0000000 -> 0xf1000000? Nov 24 17:57:43 ogra: and the armel .deb is available in debian Nov 24 19:06:14 is there a screen package for armel? Nov 24 19:14:34 yes Nov 24 19:18:18 can you direct me to it? Nov 24 19:19:38 found it, nvm. Nov 24 19:20:10 I was going to say ... Nov 24 19:20:16 apt-get install screen _should_ work Nov 24 19:20:23 even if it does install byobu for whatever reason Nov 24 19:21:30 Martyn: I was trying to grab it for an offline install because my embedded system currently doesn't have network connectivity Nov 24 19:21:47 https://launchpad.net/ubuntu/+source/screen/4.0.3-14ubuntu1.2/+build/1922902/+files/screen_4.0.3-14ubuntu1.2_armel.deb is where I ended up finding it Nov 24 19:22:09 it has some dependencies Nov 24 19:45:05 howdy! after using ubuntu for several years and doing arm coding for also about as long - i just thought it might be a good idea to combine the both. So, the obvious question... whta might be a good point to start? Nov 24 20:02:05 LetoThe2nd: What would you like to do? Nov 24 20:02:29 If you just want to use an ARM based linux device, I reccomend the beagleBoard as a good starting place. Nov 24 20:02:55 There's also the upcoming PandaBoard from TI, which is a dual core ARM platform that will be supported in Natty Nov 24 20:03:47 Martyn: hehe, the "just using" point is long passed - i have an openrd here running debian and at work i maintain an embedded platform, for which i build the environment with ptxdist. :-) Nov 24 20:05:57 but its more like being an end user at the moment, and i think i'd like to get more into the inner workings. I have reasonably good c knowledge and a little kernel experience (what it is you need to port a bsp to a closely related platform), but at the moment i'm more like: ok, i have a few building blocks and if i use them in order, it works. but what lives outside of "using existing blocks in given order"? Nov 24 20:10:33 Martyn: heh, pandaboard is already supported in maverick :P Nov 24 20:10:40 Well, yes. **** ENDING LOGGING AT Thu Nov 25 02:59:58 2010
