**** BEGIN LOGGING AT Sat Apr 21 03:00:00 2012 Apr 21 04:14:44 Newbie question: made a backup SD using win32DiskImager. Backup SD doesn't boot. Apr 21 04:14:54 how am i being dumb? Apr 21 04:20:52 he will never know Apr 21 06:02:27 ah, another penguin consumer Apr 21 06:05:09 u-boot now gets post codes? Apr 21 06:44:08 aholler, sadly no Apr 21 07:08:49 hi Apr 21 07:11:10 I build the RFS image and toolchain image with gcc and opencv as discussed yesterday, Apr 21 11:41:19 no tomatoes this year, it's too cold here, they won't grow :/ Apr 21 11:49:40 koen: ping Apr 21 11:54:17 wmat: pong Apr 21 13:14:34 rcn-ee: the 'git checkout' needs a -f for that crap psp tree with builtin conflicts Apr 21 13:14:46 rcn-ee: I'll push a fix to master once I get it working Apr 21 13:15:55 how does a git tree have builtin conflicts? Apr 21 13:18:37 when it e.g. includes a file which got generated before Apr 21 13:19:21 then git refuses to overwrite that file Apr 21 13:19:59 you mean some branches contain files that are generated on others? Apr 21 13:20:07 jupp Apr 21 13:20:23 that's annoying, but I can see how it might happen Apr 21 13:21:18 had build such myself before, therfor I remembered it ;) Apr 21 13:23:19 anyone here already build a script for a hotplug-console? Apr 21 13:24:19 koen, strange, might even be a git hidden default now, it didn't seem to have any issues here, branching, pulling that psp tree and then checking out the tree. (debian git version 1.7.9.5) Apr 21 13:25:06 switching between branches in a clean git tree is never a problem Apr 21 13:26:33 that script only pulls foreign tree's into branches with only using specific tags from master (torvalds git) Apr 21 13:27:21 mru: it's not a clean git ree Apr 21 13:27:26 rcn-ee: 1.7.10 here on osx Apr 21 13:27:46 mru: if you clone the am335x psp tree you pull in an unfinished merge Apr 21 13:27:58 wtf Apr 21 13:28:06 what, did they just push that now? Apr 21 13:29:14 I always think someones plays with a sony gameconsole when reading psp ;) Apr 21 13:29:19 a clean clone gives me files in net/ and include/net with 'unstaged changes' Apr 21 13:29:39 how is that possible? Apr 21 13:29:51 I don't know Apr 21 13:30:01 but my money is on TII messing things up again Apr 21 13:30:15 not if osx is involved ;) Apr 21 13:30:32 koen, we might want to pull a branch from argo, and just stick it on github, and use that for the script.. (that way they can't mess us up..) Apr 21 13:31:04 what we want is proper support for am33x in mainline :) Apr 21 13:31:45 yeah, thats what we really want.. ;) But we are dealing with crap. ;) Apr 21 13:38:19 humm, checked out v3.2 then pulled in the arago v3.2-staging tree, that worked fine.. Apr 21 13:48:40 koen, this is what i'm getting when switching to the beaglebone-3.2 branch.. http://pastebin.com/wZsyE7g4 Apr 21 13:49:57 rcn-ee: http://pastebin.com/msvDeuGq Apr 21 13:50:03 hi all Apr 21 13:50:03 rcn-ee: it works after adding the -f Apr 21 13:50:15 rcn-ee: anyway, 3.2.15 patchset added Apr 21 13:50:32 rcn-ee: and a fix for vga capes with a production eeprom Apr 21 13:51:35 ahh, more cool stuff.. ;) Apr 21 13:52:40 the new sd card for in the box will have 3.2.14 + vga fix Apr 21 13:52:51 when i createcylinder while partitioning, it creates but while entering the first partitions width it comes in terms of sectors, what to do ? Apr 21 13:52:58 please help me Apr 21 13:54:03 rcn-ee: after I finish building the new release I'm going to add some tweaks to the script so that will generates a complete .bb and file structure I can cp over Apr 21 13:54:40 sure, that sounds good.. anything to make things easier. ;) Apr 21 13:54:41 rcn-ee: and maybe push the tree to beagleboard/linux Apr 21 13:54:50 the resulting tree, that is Apr 21 13:54:57 for people like mdp and mranostay Apr 21 13:55:38 i tried by ./mkcard.txt /dev/sdx but it didn't work Apr 21 13:56:08 please reply me what i should do? Apr 21 13:59:18 is there any one free to help me Apr 21 14:01:45 it happed thanks Apr 21 14:32:21 <_av500_> good things happen to those who wait Apr 21 15:02:45 Please note that a notice has been posted to http://elinux.org/Main_Page indicating the intent to move from the GFDL to the CC-SA-3.0 license as the site's default license.

Apr 21 18:01:06 I don't get 3.3.2+ to boot, neither tickless on/off nor reset unused clocks on/off helps. it stops after booting the kernel. Apr 21 18:02:25 maybe it's something with the cache and u-boot. on kirkwood system you had to disable l2-cache in u-boot if patch physical to foo is enabled, but I haven't that enabled. Apr 21 18:04:01 "... booting the kernel". 3.3.0 does a bit more ;) Apr 21 18:14:27 aholler: on what hardware? Apr 21 18:17:40 c4 Apr 21 18:18:31 sometimes I really have to try to connect a jtag-dongle to that thingy. Apr 21 18:41:02 Hello! I'd like to know the basics of porting an OS(say ubuntu) on beagleboard(or any other machine). Could anyone suggest me good resources for them? Apr 21 18:41:32 I've read the BB wiki but would like to read the basics Apr 21 18:42:56 it's all done Apr 21 18:43:21 I'm sure there's _some_ os that hasn't been ported Apr 21 18:43:27 like... os/2 Apr 21 18:43:43 if you have another board, start with u-boot, then get a kernel running Apr 21 18:45:36 Well, I'm interested in knowing the whats and why of it :) Am I right to say that for porting any OS to a machine bootlader, kernel and then the OS are the steps to follow? Apr 21 18:47:11 usually the kernel is part of an os Apr 21 18:47:42 er I mean applications, window manager etc Apr 21 18:48:59 Secondly, I read about headless images for linux installation -- are they image files which won't output anything on monitor? If so, how are they installed in first place? Apr 21 20:48:59 hi all Apr 21 20:50:39 so I managed to get a USB wireless g adapter working with the beagleboard-xM (running Angstrom) but from what I can tell it's only using wireless b and not g Apr 21 20:50:58 when I set my router to g only mode, it failed to connect Apr 21 20:57:19 * aholler awaits one who asks for the lottery numbers for the next week Apr 21 21:01:21 s/#beagle/#42/ Apr 21 21:03:13 does anyone know if there is a way to see which wireless protocol you are connected to a network by? Apr 21 21:04:23 iwconfig Apr 21 21:04:34 then it just says 802.11bg Apr 21 21:04:41 but I want to know whether its using b or g Apr 21 21:05:31 do you know whats the difference between b and g? Apr 21 21:06:37 g is about 5 times faster Apr 21 21:09:43 and iwconfig only says 802.11bg? Apr 21 21:12:35 hmm actually Apr 21 21:12:42 the data rate says 54/Mbs Apr 21 21:12:46 which I guess implies that it's using g Apr 21 21:12:52 unless it's innacurate Apr 21 21:13:50 oh wait, wrong terminal window :P Apr 21 21:14:04 the beagleboard says that it's working at 1 Mb/s :/ Apr 21 21:14:58 mine does 720MHz if it's friendly Apr 21 23:50:39 guys is there chips that take i2c have i2s come out ? Apr 21 23:51:18 you mean buffers? Apr 21 23:52:17 I dunno lol Apr 21 23:52:24 what do you want it for Apr 22 00:01:38 Russ: stupid but, use the i2c wires on a hdmi port Apr 22 00:02:16 can you be more specific Apr 22 00:05:38 does anyone know if its possible to edit the boot partition on an SD card for the beagleboard-xm to load a different kernel in Angstrom wtihout changing other files on the angstrom filesystem? Apr 22 00:06:24 where will you put your loadable modules? Apr 22 00:07:04 aren't they all contained in a folder equal to the kernel's version number? Apr 22 00:07:24 so I could have the loadable modules for two different kernels simultaneously Apr 22 00:08:34 the build of the modules often change based on the configuration of the kernel Apr 22 00:08:46 how are the kernel different? Apr 22 00:09:56 well there's a newer kernel than the one I'm using that has modules available on the angstrom package repository for a wifi chip I have Apr 22 00:10:05 my current version doesn't have support for that Apr 22 00:10:25 I've been using an image builder on angstroms site to build an SD card image that has a lot of software I need installed Apr 22 00:10:38 but its an old version of the kernel that doesn't have support for the wifi chip Apr 22 00:10:56 someone told me I could install a newer kernel without getting rid of my filesystem and installed software Apr 22 00:11:26 basically that I wouldn't have to build a whole new SD card manually if I can get the new kernel to be loaded Apr 22 00:15:01 Russ maybe not nice to put here lol, considering getting a new board after somehow killing my beagle's USB. I have been considering a pandaboard but as everyone knows the beagleboard has free i2s and the other does not. So how/what do you do if you need i2s ? Apr 22 00:16:05 if you need i2s, you use a board that has i2s Apr 22 00:18:05 mru, considering it :P but having onboard bluetooth and wifi sounds tempting :\ Apr 22 00:20:32 childish I know Apr 22 00:21:12 do you need those? Apr 22 00:22:14 yea I do, I use dongles just hate them Apr 22 00:23:42 borillion, i2s is something else Apr 22 00:23:51 you mean i2c or i2s? Apr 22 00:24:29 and tawest left Apr 22 00:25:07 so nothing can take i2c to i2s, yes he did leave Apr 22 00:25:28 oh, I read the original question as "take i2c and have i2c come out" doh Apr 22 00:25:49 i2s has a lot more bandwidth than i2c typically Apr 22 00:26:29 according to wp, a 44.1kHz audio signal requieres a 2.8224MHz i2s signal Apr 22 00:27:01 no need to be according to, it's simple maths Apr 22 00:27:24 Russ, lol no was just a question about cheating and use a hdmi port as an extra io over the interface Apr 22 00:27:29 I'm not taking credit for math I didn't do Apr 22 00:27:52 borillion, the i2c on hdmi is probably a 100kHz bitrate Apr 22 00:28:25 ahh Apr 22 00:28:40 hmm, 44.1kHz * 16 bits * 2 channels gives exactly half that figure Apr 22 00:30:01 CD Audio with a sample frequency of 44.1 kHz, with 32 bits of precision per (2) stereo channels will have a bit clock frequency of 2.8224 MHz Apr 22 00:30:14 but that's not CD audio Apr 22 00:30:22 CD audio has 16 bits per sample Apr 22 00:31:17 and that's why I don't take credit for math I didn't do Apr 22 00:31:22 lol Apr 22 00:31:32 that's why you should do the maths yourself Apr 22 00:31:39 well so i2c != i2s so it does not help right :P Apr 22 00:31:55 yes, they are very very different Apr 22 00:32:11 but c and s are so similar as letters Apr 22 00:32:35 they are both from philips Apr 22 00:33:20 lol, thats true they are Apr 22 00:33:41 ...which is why the names are similar Apr 22 00:34:03 would something like this work http://www.ti.com/product/pcm1796#description Apr 22 00:36:20 way to complex nm Apr 22 00:38:20 work for what? Apr 22 00:38:24 i2c to i2s conversion? Apr 22 00:38:37 because that's a dac Apr 22 00:40:03 I know, its i2c though. Problem solved, no need to go from i2c to something else Apr 22 00:40:15 no, the control channel is i2c Apr 22 00:40:16 its configured via i2c Apr 22 00:40:30 audio data is various serial formats including i2s Apr 22 00:40:59 most audio chips are that way, audio data bus (such as i2s) and control bus (i2c or spi) Apr 22 00:41:39 i2c isn't really suitable for isochronous transfers anyway Apr 22 00:43:18 kk Apr 22 00:44:53 so i2s is still needed to send the audio data, so new beagle :P Apr 22 00:45:30 dunno what the hell I did to this one, must have been stray esd or something Apr 22 00:45:34 in the case of that chip, yes Apr 22 00:45:42 what is your end goal? Apr 22 00:46:35 5.1 audio android device Apr 22 00:49:00 have not see any daughterboards for audio, I could always use usb but I'd rather not, kind of a learning thing I suppose Apr 22 00:49:06 I don't know what that is, but what's wrong with on-board audio? Apr 22 00:49:12 or is this a panda thing? Apr 22 00:49:31 the beagleboard and pandaboard both have only stereo Apr 22 00:49:37 oh Apr 22 00:49:38 5.1 Apr 22 00:50:07 Russ :P http://en.wikipedia.org/wiki/5.1_surround_sound Apr 22 00:50:08 LOL Apr 22 00:50:10 you got it Apr 22 00:50:13 I'd look at the schematic and the datasheets first Apr 22 00:50:31 you might be able to get at 5 channels pretty easily Apr 22 00:50:44 but there is no i2s available on the expansion? Apr 22 00:52:00 I was eyeing this, for the beagleboard. Apr 22 00:52:02 http://www.cirrus.com/en/pubs/proDatasheet/cs4228a-f1.pdf Apr 22 00:52:17 Russ, if you go with panda Im told no there isn't Apr 22 00:52:35 have you looked at the datasheet for the beagleboard pmic? Apr 22 00:53:04 no mention of it in the documentation and told there is not in the panda, the beagle has i2s Apr 22 00:53:17 you should be able to find something accepting audio over spi Apr 22 00:53:37 the TPS65950 Apr 22 00:54:01 'A new feature on the –xM is the ability to access the audio signals for use on an external add on board. If this feature is to be used, you must disable via SW this interface on the TPS65950.' Apr 22 00:54:15 did you read 7.16 of the srm at all? Apr 22 00:54:41 I did see that Apr 22 00:55:33 also, do you need 5.1, or are 4 channels ok? Apr 22 00:57:07 it only supplies stereo according to the Srm in 5.4 Apr 22 00:57:18 yes, but look at the schematic Apr 22 00:57:32 I guess 4 would be ok, its not horrible :P Apr 22 00:57:38 It might be pretty easy to use the audio input as output Apr 22 00:58:33 and there might be other paths brought out on easy testpoints Apr 22 00:58:34 ugh, using two stereo pairs for 4-channel Apr 22 00:58:46 check the tps65950 datasheet and the beagle schematic Apr 22 00:58:50 I had a sound card once that did that Apr 22 00:58:57 mru, ugh, making a pcb when you don't have to Apr 22 00:59:12 yes I know some of the ac'97 realtek cards do that Apr 22 00:59:32 what really would have been nice is if one of the digital audio streams was connected up to the hdmi connector Apr 22 00:59:33 this was a cmedia chip Apr 22 00:59:45 they came out with a proper 6-channel chip later Apr 22 01:00:36 Russ: that would require a full hdmi framing chip Apr 22 01:00:46 which is more expensive than the dvi one used on the beagle Apr 22 01:01:15 my srm has no 7.16 :P Apr 22 01:01:40 rev a2-01 Apr 22 01:01:49 beagle or beagle xm? Apr 22 01:02:46 gtg, the i2s expansion board might be your only way to go, it'd be nice though because you could have digital audio out Apr 22 01:04:15 beagleboard xm Apr 22 01:04:29 A 4 pin connector is provided to allow access to the McBSP2 signals for audio Apr 22 01:04:29 applications. In order to use these signals, the audio interface on the TPS65950 must be Apr 22 01:04:29 disabled by the SW. Apr 22 01:04:56 thanks guys Apr 22 01:05:18 just going to get another BB xM Apr 22 02:47:54 hi...what OS can i use on bb-c3? i used to have angstrom but now it doesn't look like an active project. **** ENDING LOGGING AT Sun Apr 22 03:00:00 2012
