May 29 03:13:59 <kaektech> furan: huh? Do you know how to save a config file in Linux? Perhaps you should better re-format this question for a different audience.
May 29 03:19:34 <fiola> Sounds to me like furan is asking a reasonable question, and it's certainly on topic since it's for his BeagleBone.  Since this isn't #beagle-experts-only, a bit of help wouldn't go amiss.  Unfortunately there wasn't enough info in the question.  What O/S?  How did you "install" stuff only to have it vanish, to where?  Etc.
May 29 03:31:02 <furan> kaektech: obviously I do
May 29 03:31:29 <furan> all I mean is that the file system is not saved after a reboot. libs I installed with opkg are gone. files in /etc I edited before, with settings that worked, are gone
May 29 03:32:00 <furan> I'm using the stock angstrom os, on the sd card that it came with
May 29 03:32:06 <furan> s/os/distribution
May 29 03:32:39 <furan> as much as I like fanboys who go on about "you don't know how to save a file", it's just that the filesystem is in ram and not getting flushed back to the sd card, ever. I will do more research on it.
May 29 03:33:21 * furan wonders if kaektech even has a beagle device
May 29 03:34:10 <mru> ever heard of umount and/or sync?
May 29 03:34:53 <fiola> All *nix filestore is in RAM, it's only flushed out to disk asynchronously.  But that happens all the time and it's exceedingly unlikely that the dirty block buffers in RAM aren't getting written out, unless you're actually using a ramdisk instead of main filestore.  But you're not, since you're talking about /etc, which is not in ramdisk.  So youre question is valid.
May 29 03:35:34 * mru has had systems with /etc in ram
May 29 03:35:46 <mru> with everything in ram, in fact
May 29 03:35:51 <furan> the device lost power, so maybe it lost power before the changes could be flushed to disk
May 29 03:36:08 <furan> I imagine with sd it would take a while for them to get written. I installed a bunch of libs.
May 29 03:36:54 <furan> but I edited the /etc files much earlier :/  and they definitely got saved, heh
May 29 03:36:58 <fiola> Aye, very common with systems using a COW fs overlaying a readonly media.  But that's not the case for furan because he's using stock Angstrom that came with the bgeaglebone
May 29 03:37:21 <furan> thanks guys. I'll try this again and do a real shutdown and see what happens
May 29 03:37:52 <fiola> GL :-)
May 29 03:37:58 <mru> fiola: that's not what I was doing
May 29 03:39:21 <fiola> I guess it's possible that he's got an SD card that isn't write-enabled.  I know that full-size SD cards have a write switch, dunno about these transflash things
May 29 03:39:52 <furan> are there any good samples out there on going the mmap wrote for driving gpio
May 29 03:39:52 <mru> uSD cards don't have that
May 29 03:39:54 <furan> ?
May 29 03:40:57 <furan> sorry, I mean ? to the end of what I wrote
May 29 03:42:48 <fiola> furan: there's a video linked on elinux.org/BeagleBone about GPIO programming.  I haven't watched it yet though, so can't say if it's relevant.
May 29 03:42:53 <furan> haha. apparently the fs changes did get persisted, it just didn't drop the headers where I expect them (usr/inc)
May 29 03:42:56 <furan> thanks
May 29 03:43:05 <furan> er, usr/include
May 29 03:43:30 <furan> I installed libavcodec-dev, and I expect a dir called 'libavcodec' under /usr/include, no such dir. no avcodec.h under the tree of /usr/include.
May 29 03:45:51 <fiola> Ask opkg to tell you what files it's installed and where --- opkg files libavcodec-dev
May 29 03:45:56 <furan> thx
May 29 03:46:39 <furan> that's weird.
May 29 03:46:44 <furan> the package only has the .so in it
May 29 03:47:32 <furan> when I installed it on ubuntu, I got the headers. the package description on debian.org says: This package contains the header files and static libraries needed to compile applications or shared objects that use libavcodec.
May 29 03:48:00 <furan> same for libswscale-dev
May 29 03:48:02 <furan> weirder.
May 29 03:48:29 <fiola> Don't assume any similarity to Ubuntu.  Angstrom is its own specific animal
May 29 03:49:01 <furan> is there a way to do a wildcard lookup with opkg?
May 29 03:49:08 <furan> e.g. if I wanted to see libswscale-*?
May 29 03:49:19 <fiola> opkg list | grep whatever
May 29 03:49:30 <furan> got it
May 29 03:50:20 <fiola> I'm only just learning this stuff, it's all new to me since I come from the Gentoo world.  Seems fine though
May 29 03:56:03 <furan> I could just copy hte headers but I think I will just go ahead and try the ubuntu image
May 29 03:57:49 <fiola> Well the headers have to be somewhere.  If they weren't in -dev then I'd expect them to be in the two other versioned libavcodec packages
May 29 04:01:29 <furan> yeah I tried both, the later one was already installed
May 29 05:42:29 <prasant> I setup debian hard float port on my Beaglebone and the board takes twice the time to boot as compared to Angstrom. Does systemd makes that much of a difference for Angstrom? or there has been other optimizations that has been done?
May 29 05:44:38 <fiola> Angstrom is based on busybox, so a lot of utilities are much sleaker (but less functional).  I'm only just guessing since not tried Ubuntu, but I'd assume that makes quite a difference.
May 29 05:44:55 <fiola> s/Ubuntu/Debian/  sorry
May 29 05:45:34 <fiola> I'll give Debian a try as soon as I've popped out for a few SD cards
May 29 05:49:11 <prasant> fiola: yes, busybox is another good point about angstrom.
May 29 05:49:35 <fiola> Re "good", YMMV :P
May 29 07:41:47 <fiola> beaglebone$ runlevel
May 29 07:41:47 <fiola> 1
May 29 07:42:03 <fiola> beaglebone$ who -r
May 29 07:42:03 <fiola>          run-level 5  Jan  1 00:00
May 29 07:42:07 <fiola> Hahahaha
May 29 07:42:41 <av500> run level, run
May 29 07:42:45 <fiola> Poor thing, can't make its mind up :P
May 29 07:45:07 <koen> fiola: systemd has no concept of 'runlevel', but lots of apps check for numeric output from /usr/bin/runlevel
May 29 07:45:35 <mru> indeed, with systemd it's all uphill
May 29 07:45:39 <mru> both ways
May 29 07:45:50 <fiola> Ah, so who and runlevel just use different placeholder integers I guess
May 29 07:51:58 <fiola> Could replace /usr/bin/runlevel's "echo 1" by     /usr/bin/who -r | /usr/bin/awk '{print $2}'
May 29 07:52:35 <fiola> Or cut etc
May 29 07:55:32 <koen> what would that get you?
May 29 07:55:32 <koen> a slower version that's equally missleading
May 29 07:55:56 <mru> but you were already misled by lennart
May 29 07:55:59 <mru> so what's a little more?
May 29 07:56:33 <fiola> If the speed of "runlevel" matters, we'd have other issues to worry about :P
May 29 07:57:30 * av500 runs at level 99 always
May 29 07:59:08 <fiola> I don't know systemd because I come from Gentoo, but if everyone hates it so, why use it?
May 29 07:59:54 <av500> fiola: not everybody
May 29 08:00:02 <av500> a vocal minority only
May 29 08:00:12 <fiola> Heh
May 29 08:00:25 <av500> e.g. ubuntu does not use it, so all the ubuntu users cannot hate it
May 29 08:00:58 <av500> so far only fedora users have the priviledge to be able to hate it
May 29 10:19:13 <Mik__> hello guys,
May 29 10:19:37 <Mik__> I managed to screw up the SD card of my BeagleBoard xM, running Angstrom
May 29 10:19:54 <Mik__> I am recreating new images but I don't get it quite right... so the question:
May 29 10:20:18 <Mik__> is there a place where I could download the original TI image for BB xM running Angstrom Linux please?
May 29 10:20:32 <av500> sure
May 29 10:20:58 <Mik__> I found this one: Angstrom-TI-GNOME-image-eglibc-ipk-v2012.01-core-beagleboard-2012.01.11.img.gz but I was expecting a tar file...
May 29 10:21:11 <Mik__> I don't know how to handle .img :-(
May 29 10:21:39 <av500> dd handles it fine
May 29 10:21:48 <av500> and you asked for an *image*
May 29 10:21:56 <Mik__> good point :-)
May 29 10:22:14 <Mik__> I'll read about dd, thanks
May 29 10:23:35 <Mik__> I presume the idea is that I extract with dd the boot partition and the Narcisus partition and then copy them over the sd card.... as I would do using a tar?
May 29 10:25:43 <av500> no
May 29 10:25:47 <av500> it's an image
May 29 10:25:56 <av500> you just write it to the card
May 29 10:26:03 <av500> since it's an image
May 29 10:26:09 <LetoThe2nd> Mik__: http://downloads.angstrom-distribution.org/demo/beagleboard/
May 29 10:26:20 <LetoThe2nd> Mik__: "how to unpack and boot the image"
May 29 10:26:35 <LetoThe2nd> ah no, ignore me for now.
May 29 10:27:11 <aholler> cat image >/dev/mmcfoo
May 29 10:27:19 <LetoThe2nd> aholler:  if its unpacked.
May 29 10:27:28 <LetoThe2nd> if its gz, go for zcat.
May 29 10:27:47 <Mik__> it's a .img, which I am not familiar with :-(
May 29 10:27:51 <LetoThe2nd> be inspired by http://downloads.angstrom-distribution.org/demo/beaglebone/
May 29 10:29:36 <Mik__> LetoThe2nd & aholler: from these links it seems like I should just $ cat my.img > /dev/sdb
May 29 10:29:49 <Mik__> I'll try, what is the worst it can happen? :-D
May 29 10:30:53 <tasslehoff>  /dev/sdb could be one of your HDDs/SSDs
May 29 10:31:29 <Mik__> I'm quite sure /dev/sdb is the one, as it shows up properly using gparted....
May 29 10:44:49 <tasslehoff> Mik__: good to go then. someone here chose the wrong partition once, so I'm cautious :)
May 29 10:46:14 <Mik__> tasslehoff: you are absolutely right :-)
May 29 11:20:57 <Andi> Hello, I installed ArchLinuxARM on my BeagleBoard-xM Rev C and now the Ethernet and USB is not working! Can someone please help me?
May 29 11:21:16 <av500> does not work does not work: https://plus.google.com/u/0/108138837678270193032/posts
May 29 11:25:16 <Andi> Hello, I installed ArchLinuxARM on my BeagleBoard-xM Rev C and now the Ethernet and USB is not working! Can someone please help me?
May 29 11:38:49 <Andi> Hello, I installed ArchLinuxARM on my BeagleBoard-xM Rev C and now the Ethernet and USB is not working! Can someone please help me?
May 29 12:57:25 <Mik__> sorry guys, I am now really frustrated! I can't manage to recreate a working img with Angstrom Linux.
May 29 12:57:30 <Mik__> I followed this: http://downloads.angstrom-distribution.org/demo/beagleboard/
May 29 12:57:36 <Mik__> and it doesn't even boot
May 29 12:58:18 <Mik__> although it is suspicious as it creates two partitions named 'boot' and 'Angstrom', while the instructions seem to refer to 'rootfs' partition for the file system
May 29 12:58:33 <Mik__> but I thought that this approach should work:
May 29 12:58:43 <Mik__> cat tiImage.img > /dev/sdb
May 29 12:59:03 <Mik__> but it doesn't write it as it gives me permission denied even when running as sudo
May 29 12:59:03 <av500> Angstrom-TI-GNOME-image-eglibc-ipk-v2012.01-core-beagleboard-2012.01.11.img.gz
May 29 12:59:11 <av500> this one
May 29 12:59:51 <Mik__> Ok, I'll try that. I guess I will unzip it first right?
May 29 13:00:05 <ogra_> just use zcat
May 29 13:00:15 <Mik__> although I don't think I should have got 'permission denied' with a wrong image....???
May 29 13:00:34 <av500> cat does not care for that image it writes
May 29 13:00:40 <ogra_> are you trying to cat as a user to the disk device ?
May 29 13:01:01 <av500> for what*
May 29 13:01:02 <ogra_> you need to have full write permission to /dev/sdb in your case
May 29 13:01:09 <Mik__>  sudo cat Angstrom-TI-GNOME-image-eglibc-ipk-v2012.01-core-beagleboard-2012.01.11.img >/dev/sdb
May 29 13:01:18 <ogra_> that wont work
May 29 13:01:38 <ogra_> use sudo -s
May 29 13:01:49 <ogra_> and then cat or zcat
May 29 13:02:12 <ogra_> in your command above the sudo applies to the cat, but not to the redirect
May 29 13:02:29 <ogra_> (i.e. >/dev/sdb is executed as a user)
May 29 13:02:32 <Mik__> ah! thanks for explaining this
May 29 13:03:05 <Mik__> $ sudo -s zcat Angstrom-TI-GNOME-image-eglibc-ipk-v2012.01-core-beagleboard-2012.01.11.img >/dev/sdb
May 29 13:03:16 <ogra_> you could use something like "cat foo.img | sudo tee /dev/foo" ...
May 29 13:03:25 <Mik__> still a problem about permissions
May 29 13:03:26 <ogra_> no, sudo -s
May 29 13:03:33 <av500> or dd and a bs=4M to maybe make it faster
May 29 13:03:33 <ogra_> not any command after that
May 29 13:03:39 <ogra_> it will give you a root shell
May 29 13:03:46 <av500> sudo su
May 29 13:03:53 <ogra_> yeah, dd is better than tee for sure
May 29 13:04:00 <Mik__> ok, I am understanding now (I hope:)
May 29 13:04:00 <ogra_> dont use sudo su ...
May 29 13:04:17 <ogra_> sudo su will carry over the user env
May 29 13:04:25 <aholler> sudo "zcat img >foo"
May 29 13:04:37 <ogra_> yeah, quoting helps too
May 29 13:04:37 <av500> sudo su -
May 29 13:04:55 <Mik__> now it is going... thanks guys!
May 29 13:05:01 <ogra_> that should work, though i would still rather rely on sudo doing the right think with -s or -i
May 29 13:05:07 <aholler> without the quotes you are just sending the nothing to foo
May 29 13:05:18 <aholler> nothing = output of zcat
May 29 13:05:33 <av500> zmiaow
May 29 13:05:53 <aholler> hmm, wrong, anyway, just use quotes or get root ;)
May 29 13:05:53 <dm8tbr> zLOLCAT?
May 29 13:06:16 <av500> dm8tbr: yes, for zlul
May 29 13:06:29 <av500> zlulz in fact
May 29 13:06:46 <Mik__> :-D
May 29 13:07:11 <dm8tbr> zlolcat has invisible bike^woutput!
May 29 13:07:29 * koen boards the roflcopter
May 29 13:08:19 <aholler> cats are totally stupid. the one of my parents no learned, after 3 years, how to climb down a ladder, but he is too stupid to climb back up.
May 29 13:08:21 <dm8tbr> .oO(lolcat and roflcopter extensions for cowsay...)
May 29 13:09:36 <MrDuck> hello, does someone have experience with qemu-omap3? It segfaults when starting a working beagle_cx image
May 29 13:09:44 <ogra_> aholler, its a matter of perspective ... if you carry the cat up the ladder once it doesnt get back up, i would actually call it a clever cat :)
May 29 13:10:26 <aholler> my parents have to go down to open the door to let the cat back in ;)
May 29 13:10:41 <ogra_> heh, even cleverer
May 29 13:11:07 <av500> stupid cat is clever
May 29 13:12:42 <angs> I formated SD cards of 3 bones according to Angstroms' webpage, then did "opkg update and upgrade". I get "[    0.672347] EXT4-fs (mmcblk0p2): INFO: recovery required on readonly filesystem" on dmesg. how can I fix the problem?
May 29 13:13:21 <av500> dont upgrade :)
May 29 13:13:32 <av500> and get better sd cards
May 29 13:13:43 <angs> they are the SD cards that comes with bone
May 29 13:13:45 <av500> is that the only errro on dmesg?
May 29 13:14:00 <aholler> man shutdown
May 29 13:14:15 <angs> [    9.354180] EXT4-fs (mmcblk0p2): ext4_orphan_cleanup: deleting unreferenced inode 9418
May 29 13:14:29 <angs> I couldnt see any another abnormality
May 29 13:15:07 <av500> I guees ext4 and that sdcard dont like each other
May 29 13:15:09 <angs> the full dmesg > http://pastebin.com/DisBb86f
May 29 13:15:21 <angs> should I format it again?
May 29 13:15:32 <angs> or change the file system?
May 29 13:16:22 <av500> angs: this dmesg is after booting
May 29 13:16:27 <av500> no?
May 29 13:16:40 <angs> no after update and upgrade
May 29 13:16:50 <angs> I didnt see any error msg after that operation
May 29 13:17:14 <av500> no
May 29 13:17:17 <av500> its a boot log
May 29 13:17:25 <av500> the error is reported when mounting the ext4
May 29 13:18:00 <MrDuck> does anyone know qemu-omap3? for me it segfaults on startup. any tutorials/ideas?
May 29 13:18:05 <MrDuck> thx!
May 29 13:18:44 <angs> do you think that formating and installation angstroms dist was not successful?
May 29 13:19:28 <av500> installing angstrom does not involve "opkg upgrade"
May 29 13:20:10 <riskable> angs: Do you still want my Angstrom image with the 8192cu driver?
May 29 13:20:28 <angs> yes riskable, I was checking your webpage but could not see any new thread
May 29 13:20:36 <angs> related 8192cu
May 29 13:20:57 <riskable> angs: When I said I'll put it on "riskable.com somewhere" I meant I'd just upload it to riskable.com/files or something :)
May 29 13:21:11 <angs> ah ok :)
May 29 13:21:11 <riskable> I didn't mean I'd post a blog update.  I haven't updated that blog in years, LOL
May 29 13:21:15 <angs> I did not know it
May 29 13:21:19 <riskable> I'll make an image for you now :)
May 29 13:21:29 <angs> thank you very much :)
May 29 13:22:25 <ogra_> angs, did you properly unmount the SD after writing the angstrom image to it ?
May 29 13:22:51 <riskable> angs: How do you want it?  As a whole SD card image or just two tarballs containing the filesystems in question?
May 29 13:22:59 <ogra_> sounds like the kernel just detects on boot that it wasnt properly unmounted, then this message is totally normal
May 29 13:23:14 <angs> <riskable>: I would appreciate for the whole SD card
May 29 13:23:32 <riskable> angs: OK, I'll make a dd image of the entirety of /dev/sdc for ya
May 29 13:23:35 <angs> ogra_: I did not unmounted it
May 29 13:23:40 <ogra_> aha
May 29 13:24:10 <ogra_> then it is an expected message ... you could put it back into your PC and do an fsck
May 29 13:24:22 <angs> riskable: thanks a lot
May 29 13:24:30 <ogra_> (and make sure it was properly unmounted etc so it doesnt come up again)
May 29 13:24:48 <angs> <ogra_>: thank you, I did not think about it
May 29 13:25:07 <angs> I will load riskable's image
May 29 13:25:16 <riskable> angs: No problem.  Running "dd if=/dev/sdc of=/storage/beagleboard/angstrom_working_somewhat_8192cu_dd_image.img" right now :)
May 29 13:26:35 <riskable> For reference, this is Angstrom built from the latest git repos two days ago with the Realtek 8192cu driver copied into /lib/modules/3.2.16/kernel/driver/net/wireless/rtlwifi
May 29 13:27:12 <riskable> If you have your USB dongle plugged in when you boot up you can start it up with "ifup wlan0"
May 29 13:27:37 <riskable> I just realized that I left /etc/network/interfaces configured to connect to my ESSID...  So edit that file before you run "ifup wlan0"
May 29 13:28:18 <angs> thanks a lot
May 29 13:28:45 <koen> stay away from /etc/network/interfaces
May 29 13:28:45 <angs> could you give me the download link of the image file?
May 29 13:28:49 <koen> have a look at http://ladyada.net/products/beaglebone/wifi.html
May 29 13:31:01 <angs> it is very good tutorial, thank you
May 29 13:34:40 <riskable> angs: Uploading to my server now...  Will take a few minutes
May 29 13:35:43 <angs> riskable: ok thanks, I am looking forward to have the link
May 29 13:36:41 <riskable> angs: When it is done it will be here:  http://riskable.com/files/angstrom_working_somewhat_8192cu_dd_image.img.gz
May 29 13:37:04 <koen> give http://dominion.thruhere.net/koen/angstrom/beaglebone/Angstrom-Cloud9-IDE-GNOME-eglibc-ipk-v2012.05-beaglebone-2012.05.24.img.xz a try first
May 29 13:38:02 <riskable> angs: I'll also upload the original files I used to create the image while I'm at it
May 29 13:39:14 <ogra_> koen, oh, cloud9 ? so TI is into cloud computing now ? :)
May 29 13:39:26 <riskable> koen: I didn't use conman because I wanted the ability to bring wlan0 up and down trivially while I switched drivers WHILE I still had eth0 connected
May 29 13:42:33 <riskable> angs: FYI:  the upload should be done in 10-15 minutes
May 29 13:43:50 <angs> I downloaded angstrom_working_somewhat_8192cu_dd_image.img.gz

May 29 13:46:16 <Sh0rtWave> Hi all
May 29 13:46:19 <riskable> Yeah, it's not done yet!
May 29 13:46:32 <Sh0rtWave> I'm working with a Beagleboard xM Rev C
May 29 13:46:39 <riskable> angs: I'm still uploading it
May 29 13:46:47 <Sh0rtWave> and I'm running into similar problems as mentioned with serial Errata #8
May 29 13:46:47 <angs> ok
May 29 13:46:56 <Sh0rtWave> at least initially I was
May 29 13:46:57 <riskable> The scp command says it still has about 5 minutes to go
May 29 13:47:00 <Sh0rtWave> now I can't get it to work at all
May 29 13:47:11 <riskable> Here's the md5sum for when you do get it:  9dd387ac7a8145f3a085461100d81b0b
May 29 13:47:22 <angs> thank you
May 29 13:47:49 <riskable> The file size is 698M
May 29 13:48:00 * riskable is happy to have 5Mbit upload today
May 29 13:49:19 <Mik__> av500: the image you suggested seems to work fine - thanks! The video resolution must be changed, but I don't care about that.
May 29 13:49:38 <riskable> koen: For reference the rtl8192cu driver in the default build just plain doesn't work.  It is permanently stuck thinking rfkill is soft-locked and the rfkill command won't let you turn off the soft lock
May 29 13:50:20 <riskable> I got Realtek's 8192cu driver working but the result isn't the greatest...  Pretty much 50% packet loss no matter what I do
May 29 13:51:38 <riskable> angs: The upload is done.  Grab it:  http://riskable.com/files/angstrom_working_somewhat_8192cu_dd_image.img.gz
May 29 13:52:10 <angs> <riskable>: Thanks a lot
May 29 13:53:00 <riskable> angs: I also uploaded the driver itself (which I just compiled fresh):  http://riskable.com/files/8192cu.ko
May 29 13:53:35 <Sh0rtWave> Here's a question
May 29 13:53:46 <av500> Russ: !!!!
May 29 13:53:58 <Russ> morning
May 29 13:54:02 <Sh0rtWave> I'm using an FTDI FT232R serial breakout. This is *intended* for RS-232.
May 29 13:54:15 <Sh0rtWave> it worked a few times, but now I get nothing but noise
May 29 13:54:19 <angs> I am download them, thanks a lot riskable
May 29 13:54:20 <riskable> angs: That file might "just work" in an existing Beagleboard image if it is running kernel 3.2.16...  Just copy it to /lib/modules/3.2.16/kernel/driver/net/wireless/rtlwifi/ and run "depmod -a".  Then "modprobe -r rtl8192cu" and "modprobe 8192cu" and try it out
May 29 13:54:34 <Sh0rtWave> which makes me wonder a couple of things, like maybe if there's a problem with serial levels but I have no way to find out at the moment.
May 29 13:54:40 <Sh0rtWave> I need to get an oscope
May 29 13:54:42 <riskable> So you could try it now while you're waiting for the larger download to finish :)
May 29 13:55:57 <aholler> Sh0rtWave: disconnect the dongle, unload the driver, reconnect the dongle
May 29 13:56:20 <Sh0rtWave> with the beagleboard powered up I presume?
May 29 13:56:40 <Sh0rtWave> This isn't so much a dongle as a sparkfun prototyping module
May 29 13:57:01 <aholler> s/dongle/usb-plug/
May 29 13:57:07 <koen> riskable: http://ladyada.net/products/beaglebone/wifi.html
May 29 13:57:13 <koen> riskable: that deals with the rfkill issues
May 29 13:57:26 <Sh0rtWave> didn't help
May 29 13:57:30 <Sh0rtWave> Still got loads of noise
May 29 13:57:33 <cboyd> i buillt the systemd-gnome-image for my beagleboard using oe-core. My beagleboard boots successfully.  However, my usb mouse and keyboard does not work? Does anyone have any idea what is wrong?
May 29 13:57:46 <riskable> koen: I followed that tutorial and it didn't work.  I got the rfkill issues
May 29 13:57:52 <koen> cboyd: install the usbhid module
May 29 13:59:11 <aholler> Sh0rtWave: check cables if you have friggled it together yourself
May 29 13:59:24 <riskable> I'm trying now from scratch though...  Since I just made a whole-SD image backup :)
May 29 14:02:22 <Sh0rtWave> aholler: custom-built DB9 straight-through to a breadboard connection to my FT232
May 29 14:02:35 <Sh0rtWave> aholler: It DID work a few times
May 29 14:02:51 <Sh0rtWave> with both of the modules I have
May 29 14:05:03 <aholler> then put away whatever cables you have lying next to your connection beagle <-> breakout.
May 29 14:05:16 * Russ observes some very solid construction in an MLS listing, "5 inch 3/4 inch thick oak hardwood floor"
May 29 14:09:49 <av500> Russ: read your g+
May 29 14:11:10 <Russ> I know :)
May 29 14:11:28 <Russ> I finally got one
May 29 14:11:40 <av500> then buy us all beer!
May 29 14:11:57 <Russ> as soon as bunny sends the beer for life certificate
May 29 14:12:18 <Russ> I'll actually be in dfw tonight...so
May 29 14:13:43 <cboyd> i buillt the systemd-gnome-image for my beagleboard using oe-core. My beagleboard boots successfully.  However, my usb mouse and keyboard does not work? Does anyone have any idea what is wrong?
May 29 14:13:52 <cboyd> sorry for the second post ... i got disconnected
May 29 14:15:43 <koen> cboyd: install kernel-module-usbhid
May 29 14:16:16 <koen> jkridner: arrived at the office?
May 29 14:18:45 <jsabeaudry> If I write a file and pull the plug on my beaglebone shortly after, is it possible that the file will not be saved properly?
May 29 14:19:25 <aholler> yes, use sync to avoid most problems without shutdown
May 29 14:20:59 <jsabeaudry> aholler, are you referring to /bin/sync?
May 29 14:21:33 <aholler> there is a sync-option for the fs too, but that will slow down everything a lot
May 29 14:21:41 <cboyd> koen: thanks.  Why is this module not installed by default?  Just curious.
May 29 14:23:10 <koen> cboyd: between 3.0 and 3.2 a lot of things were turned into modules, we're still working out which ones are needed
May 29 14:23:55 <koen> in other news: 16d2bbe linux-mainline 3.2.18: build in usbhid and tsc2007 and run 'make oldconfig'
May 29 14:23:58 <koen> :)
May 29 14:26:44 <cboyd> koen: thanks alot.  Could you tell me where I can find documention detailing how to use the dsp on the beagleboard? Also, could you tell me where I can find information on installing and using gstreamer on the beagleboard?
May 29 14:27:57 <MrDuck> Hi Minou1!
May 29 14:28:11 <cboyd> koen: I'm asking because I am working on the dm8148 platform which also uses the Cortex A8 and a DSP which combines the features of the C67x+ C64x+ DSPs.
May 29 14:29:24 <Minou1> Hi MrDuck ;)
May 29 14:35:23 <arcanescu> Well I had a SD card with FS mounted on it... apparently something happened and now it doesnt enter "Run level 5" and mount devices.... could this be SD card corruption?
May 29 14:36:58 <av500> cboyd: and what dsp framework are you usign on dm8148 ?
May 29 14:40:43 <arti_t> hi all, i have tried to excess GPIO pins of Beagle-xm, i have inserted LED to GPIO pins and frm command line i sent high and low value, i noticed on odd number of GPIO pins, my experiment works and LED bliks, but on even number GPIO i am not able to off the LED
May 29 14:41:10 <av500> that's odd
May 29 14:41:14 <arti_t> can anyone tell me why i m not able to make it off
May 29 14:42:14 <W1N9Zr0> did you configure the pin mux correctly?
May 29 14:43:23 <arti_t> W1N9Zr0, i saw in bb-xm reference manual for GPIO pin-mux
May 29 14:43:34 <arti_t> according to it i m doing
May 29 14:43:39 <cboyd> av500: I'm using DSP 674x
May 29 14:45:48 <koen> cboyd: opkg install gstreamer-ti
May 29 14:45:50 <arcanescu> av500: whats odd?
May 29 14:46:02 <koen> cboyd: but dm3730 and dm81xx are vastly different
May 29 14:46:11 <arcanescu> does sd card manufacturer matter aswell?
May 29 14:46:11 <koen> (and equally unsupported in the dsp department)
May 29 14:47:15 <cboyd> koen: i have to build gstreamer from scratch using openembedded.
May 29 14:48:38 <riskable> OK, after rebuilding from scratch and following the adafruit instructions for the rtl8192cu USB wifi dongle it works...  But I still have the 50% packet loss problem :(
May 29 14:48:50 <riskable> Actually, more like 80% packet loss now
May 29 14:49:18 <aholler> good dongle
May 29 14:49:28 <av500> cboyd: yes, so how are you using the 674x on the 8148?
May 29 14:50:41 <cboyd> av500: I am trying to play some video using the DSP and gstreamer
May 29 14:51:35 <av500> and, can you?
May 29 14:52:26 <av500> and isnt video handled by the HDVICP and not the DSP?
May 29 14:52:30 <av500> on the 8148?
May 29 14:52:45 <cboyd> av500: no, my video looks more like a slide show
May 29 14:53:03 <aholler> hmm, I think that tusb<->msp430 rs232-connection on the launchpad is just unusable for transmitting more than a few byte in sequence... Looks like I have to use an avr instead.
May 29 14:53:25 <cboyd> av500: I'm trying to watch the big buck bunny video using gst-launch playbin2
May 29 14:54:07 <cboyd> av500: I thought you could also use the DSP for video
May 29 14:54:17 <av500> I guess you can
May 29 14:54:23 <av500> with the right codecs
May 29 14:54:52 <av500> koen: do you know that Rainer König guy?
May 29 14:55:09 <arcanescu> You can use DSP for video.....
May 29 14:55:11 <cboyd> av500: I just want the video to look reasonable.  I will investigate HDVICP
May 29 14:55:20 <arcanescu> isnt that what gstreamer TI's TIDmaiVideoSink does?
May 29 14:55:30 <av500> arcanescu: we are talking dm8148
May 29 14:55:43 <av500> and TIDmaiVideoSink  is a sink, as the name says
May 29 14:55:45 <arcanescu> i have used it on dm365
May 29 14:56:05 <arcanescu> dm6446 and dm368
May 29 14:56:41 <arcanescu> yes it is a sink that renders video to a composite or component pal or ntsc....
May 29 14:56:55 <av500> even to dvi on the beagle
May 29 14:57:00 <arcanescu> yup
May 29 14:57:23 <av500> but I still dont get whether cboyd wants to use beagle or 8148
May 29 14:57:27 <av500> or both
May 29 14:58:13 <arcanescu> yes well that is what i meant when i said he could use the DSP for video render.... on the beagle... ive tested that...
May 29 14:58:23 <arcanescu> you can even render on beagle using ximagesink
May 29 14:58:45 <arcanescu> *xvimagesink... I tested that using wifi - udp
May 29 14:59:05 <arcanescu> that is on a beagle and not on 8148 rather 365's 6446 and 368
May 29 14:59:16 <av500> you cannot use the dsp to render video, you can use it to decode video
May 29 14:59:40 <av500> and yes, that is exposed e.g. on the ti gst stuff
May 29 14:59:48 <av500> which some people claim is abandonware
May 29 14:59:53 <arcanescu> oh yes sorry 'decode'
May 29 15:00:01 <arcanescu> I think it works well
May 29 15:00:30 <arcanescu> for the TI plugin I recommend not goin witht he main branch
May 29 15:00:37 <arcanescu> rather checkout this DDOMPE branch
May 29 15:00:53 <arcanescu> it works like a charm.... better performance than the main branch
May 29 15:01:00 <riskable> The problem with my rtl8192cu USB wifi adapter seems to be that it works fine for a moment after conman connects it to the network but shortly thereafter it stops working altogether
May 29 15:01:36 <arcanescu> av500: why abandonware?
May 29 15:01:59 <av500> judging from spending quite some time in #gst-ti
May 29 15:02:30 <av500> but maybe the real support is on e2e
May 29 15:03:54 <arcanescu> that is true... and i will second you on that it sucks on support
May 29 15:04:11 <arcanescu> e2e doesnt have much either.... check gst-ti forums... they are dead aswell...
May 29 15:04:33 <arcanescu> but then again most questions are reiterations of previous ones....
May 29 15:04:55 <arcanescu> i was thinking of putting up a blog and putting this to rest once and for all... but I havent had the time
May 29 15:09:08 <arcanescu> the only support is from RidgeRun people.... where their patches are helpful they seldom reply on emails or otherwise.... its always "dump everything pay me aload of money and use my stuff"
May 29 15:10:03 <av500> arcanescu: that is understandable
May 29 15:10:06 <aholler> riskable: and dmesg doesn't say anything? maybe it will work with 3.6 when usb is fixed ;)
May 29 15:10:10 <av500> ridgerun needs to earn money
May 29 15:10:29 <riskable> aholler: You mean kernel 3.6?  hehe
May 29 15:11:06 <arcanescu> well sure go ahead... but if someone asks a simple question and they ahve already solved it rather than providing a simple solution you cant say abadon ship and jump on mine
May 29 15:11:22 <riskable> I don't get it:  How does conman get wlan0 'up' at all?  Every time I try to do it by hand it says "ifconfig: SIOCSIFFLAGS: Operation not possible due to RF-kill"
May 29 15:11:37 <arcanescu> its ridciulous for a simple one man consumer.... charge businesses.....
May 29 15:11:48 <arcanescu> they quoted me 100000$ for support
May 29 15:13:16 <av500> arcanescu: that is understandable
May 29 15:13:46 <av500> though 100k is excessive
May 29 15:13:58 <av500> we didnt pay that much in the past
May 29 15:14:10 <arcanescu> are you guys using it aswell?
May 29 15:14:16 <av500> no
May 29 15:14:32 <av500> but we did video decode on omap3
May 29 15:14:39 <av500> not via gst and RR
May 29 15:14:44 <av500> but others
May 29 15:15:24 <arcanescu> hmmm....
May 29 15:15:45 <abw_> Hi! Is it OK to ask a noob question here?
May 29 15:15:57 <av500> depends
May 29 15:16:03 <arcanescu> no we only talk clever stuff here
May 29 15:16:07 <arcanescu> liek quantum cryptography
May 29 15:16:15 <av500> and rocket surgery
May 29 15:16:16 <arcanescu> and particle entaglement
May 29 15:16:28 <abw_> rocket surgery?
May 29 15:16:30 <koen> av500: rainer works for fujitsu and has a 814x product
May 29 15:16:35 <arcanescu> our jokes are also about nuetrinos
May 29 15:16:43 <av500> and oldtrinos
May 29 15:16:50 <arcanescu> well yes that too
May 29 15:17:06 <abw_> I would like to update my beaglebone ubuntu 12.04 kernel because of sound issues (external usb speakers). I'm currently using the 3.2.0-psp1 Robert Nelson kernel. Are there any newer pre-compiled kernels available for download or should I compile them myself?
May 29 15:17:10 <av500> koen: 8148 i figured
May 29 15:17:42 <dpdonny> Why does the BeagleBone U-Boot config (am335x_evm) build with the ti81xx SoC and not OMAP3?
May 29 15:17:54 <aholler> abw_: usb is broken in kernels >=3.3
May 29 15:18:03 <aholler> (on omap)
May 29 15:18:27 <av500> dpdonny: because the bone is not an omap3
May 29 15:18:52 <av500> and ti silicon naming is crazy
May 29 15:19:15 <abw_> I've read something about v3.2.16-x11
May 29 15:19:17 <arcanescu> what goes through their mind when they name it?
May 29 15:19:19 <ogra_> yeah, they should ask mark shuttleworth about it
May 29 15:19:58 <av500> arcanescu: acid
May 29 15:20:06 <aholler> 0map
May 29 15:20:22 <av500> yes, they smoke finely ground omap1 chips...
May 29 15:20:23 <arcanescu> what does that even mean
May 29 15:20:39 <arcanescu> omap
May 29 15:22:15 <abw_> I'm not even sure if updating the kernel would help, its just a wild guess…
May 29 15:22:33 <abw_> the sound at the moment is choppy and stuttering
May 29 15:22:49 <dpdonny> thanks av500....the beagleboard is built with OMAP3....do the beagleboard and beaglebone use different CPUs?
May 29 15:22:59 <av500> yes
May 29 15:23:05 <av500> omap3 vs am335x
May 29 15:23:37 <dpdonny> thanks for clearing up my confusion...i thought OMAP was the platform the am335x was built on...my misunderstanding...thanks again
May 29 15:23:51 <av500> OMAP is a label that TI slaps on stuff
May 29 15:24:04 <av500> like all the other labels they slap on stuff
May 29 15:24:15 <dpdonny> is TI8XX similarly used as a label like OMAP?
May 29 15:24:48 <av500> no
May 29 15:25:05 <av500> it's ... complicated
May 29 15:25:51 <dpdonny> OK, so the Ti8XX SOC used to build beaglebone and am335x EVM is similar to some other TI8XX EVM?
May 29 15:26:10 <av500> the bone uses an am335x SoC
May 29 15:26:15 <koen> there is no beagle with 81xx
May 29 15:26:20 <koen> thank $deity for that
May 29 15:26:28 <av500> which in architecture is similar to the Ti8XX stuff
May 29 15:26:36 <dpdonny> i understand that, but from a U-Boot build configuration it uses the TI8XX SoC
May 29 15:26:47 <dpdonny> that makes sense av500
May 29 15:26:47 <av500> [17:26:28] <av500> which in architecture is similar to the Ti8XX stuff
May 29 15:27:23 <koen> am33xx is more similar to omap4 than to 81xx
May 29 15:27:45 <dpdonny> i'm porting U-Boot and Linux to a custom platform that is very similar to beaglebone so i am choosing the most comparable SOC from a build perspective
May 29 15:27:58 <koen> TI claims it's similar so the people who added am33xx support to the 81xx code don't look like they've wasted their time
May 29 15:28:39 <arcanescu> av500: you worked for TI?
May 29 15:28:46 <av500> arcanescu: heavens, no
May 29 15:29:05 <arcanescu> okay I just thought :p
May 29 15:29:16 <angs> what is the meaning [ 454.353778] here yada.net/products/beaglebone/wifi.html after the "root@beaglebone:~# systemctl restart connman.service"
May 29 15:29:19 <av500> koen did
May 29 15:29:41 <arcanescu> he enjoyed it so much he left?
May 29 15:29:46 <av500> yes
May 29 15:30:07 <av500> he was tired explaining part numbers
May 29 15:30:20 <dpdonny> @koen: would you recommend building & configuring the am335x using the omap4 SoC instead of TI8XX SoC?
May 29 15:30:26 <av500> no
May 29 15:30:34 <koen> use the AM335x one
May 29 15:30:35 <arcanescu> hahah :]
May 29 15:32:00 <dpdonny> thats what i'm doing ... the am335x_evm board config uses TI8xx SOC...I'll just modify the Ti8XX code (need to boot from NOR)
May 29 15:32:12 <f11f12> ls
May 29 15:32:21 <dpdonny> just wanted to make sure i was no the right path
May 29 15:33:45 <koen> dpdonny: 17:27 < koen> TI claims it's similar so the people who added am33xx support to the 81xx code don't look like they've wasted their time
May 29 15:34:13 <koen> dpdonny: so yes, it selects some 81xx option, but only because the engineers were lazy
May 29 15:34:28 <koen> just look at the code
May 29 15:34:36 <koen> if (omap3) do something
May 29 15:34:53 <dpdonny> thats exactly what i figured...(lazy engineers), but need to make descion for my BSP (ti8xx or something else)
May 29 15:35:05 <koen> if (81xx) do { if (am335x) {do foo} else do bar }
May 29 15:35:16 <dpdonny> yuck~
May 29 15:35:18 <koen> dpdonny: there is no decision to make
May 29 15:35:22 <av500> dpdonny: basically TI has a large pool oF IP blocks that they slap together in random ways to make SoCs
May 29 15:35:31 <koen> dpdonny: there is only one set of code for uboot and one set of code for the kernel
May 29 15:35:39 <av500> and then assign random names
May 29 15:35:41 <dpdonny> so stick with ti8xx and modify it as needed
May 29 15:36:24 <koen> dpdonny: get the am335x 'sdk' from ti and use that
May 29 15:36:34 <koen> that has am335x code for uboot and the kernel
May 29 15:36:53 <riskable> Are there any well-known-to-work-well USB wifi dongles?
May 29 15:36:57 <riskable> ...for the Beaglebone
May 29 15:37:14 <riskable> This one only cost me $7 so I'm willing to write it off as just a POS :)
May 29 15:37:48 <dpdonny> i have the sdk....already have u-boot and kernel booting the beaglebone without using the SDK...dont want to be tied to an SDK.
May 29 15:38:02 <scromp> adafruit is selling a teensy little one they say works: https://www.adafruit.com/products/814
May 29 15:38:10 <riskable> scromp: That's the same one I have :(
May 29 15:38:19 <riskable> It works for a time but then stops working altogether
May 29 15:38:19 <scromp> no good?
May 29 15:38:22 <scromp> doh
May 29 15:38:26 <riskable> Very unreliable
May 29 15:38:33 <riskable> ...and yes, I'm on 5V power
May 29 15:39:18 <dpdonny> thanks for the info koen & av500! very helpful...
May 29 15:44:48 <aholler> riskable: try limiting the traffic through iptables
May 29 15:45:07 <aholler> or tc
May 29 15:45:24 <dpdonny_> @koen: the SDK uses Ti8XX as well
May 29 15:45:31 <riskable> aholler: Why?  That would just artificially limit the speed.  What would be useful to me is if I could limit the bitrate that it tries to maintain on the RF
May 29 15:45:53 <riskable> aholler: For example, if I could force it to use 802.11b it might be more reliable.
May 29 15:46:09 <koen> riskable: use the 'iw' tool
May 29 15:46:15 <aholler> then try that
May 29 15:46:16 <riskable> iw gives me errors
May 29 15:46:27 <riskable> I also installed wireless-tools and those give me errors too
May 29 15:46:42 <aholler> limiting the usb-traffic might help
May 29 15:47:01 <riskable> I mean "iw wlan0 set bitrates legacy-2.4 12 18 24" works without errors but it doesn't do anything.  It still shows as 150Mbs
May 29 15:48:34 <aholler> iwconfig wlan0 rate 11M
May 29 15:49:43 <aholler> or maybe your psu just hasn't enough power.
May 29 15:50:49 <aholler> some wifi-dongles are in need for a lot of power (up to 500mA).
May 29 15:51:23 <riskable> My PSU is 5v 2000mA
May 29 15:51:51 <riskable> This doesn't seem to do anything at all"iwconfig wlan0 rate 11M"
May 29 15:54:05 <educa> riskable, is that with the adafruit usb wifi dongle ?
May 29 15:54:18 <educa> I'm also looking to buy such one to make my BB wireless
May 29 15:54:25 <riskable> educa: Same chip, not the actual one from Adafruit
May 29 15:57:55 <Sh0rtWave> I swear, I think there's something either to do with serial levels or something
May 29 15:58:16 <Sh0rtWave> I hit enter, and I see it responding to the traffic, but it responds with garbage
May 29 15:58:24 <Sh0rtWave> autoboot seems to be working tho
May 29 15:59:22 <Sh0rtWave> Ooh
May 29 15:59:33 <Sh0rtWave> I wonder if it's got to do with a floating ground...
May 29 15:59:35 <arcanescu> riskable: do you have any other wifi systems running in the vicinity?
May 29 16:00:11 <aholler> no gnd isn't a good idea when using a serial
May 29 16:01:16 <aholler> use at least 3 cables, not 2
May 29 16:04:09 <f11f12> u-boot on the am335x beagle bone lists i2c devices on all i2c addresses when I do "i2c probe". Is this a known "feature"?
May 29 16:05:48 <stuk_gen> is there a problem with the netbase_4.47 package? i'm build a system-gnome-image but i get error ERROR: Function failed: Fetcher failure for URL: 'ftp://ftp.debian.org/debian/pool/main/n/netbase/netbase_4.47.tar.gz'. Checksum mismatch!
May 29 16:06:59 <riskable> arcanescu: Yeah, loads...  But the 'vicinity' problem isn't a problem.  I tried using this USB dongle out by its lonesome about five feet from the AP
May 29 16:07:13 <riskable> Still had the "complete disconnect after a minute or so" problem
May 29 16:07:18 <jay6981> they probably changed the tarball but didn't update the version number
May 29 16:07:29 <jay6981> or it got hacked
May 29 16:07:42 <arcanescu> riskable: hmmm i known to have RF interference cause this problem and packet losses.
May 29 16:07:48 <riskable> BTW:  I got it to drop to 802.11b but it still has the same problem.
May 29 16:07:58 <arcanescu> even though wifi changes channel but if you have something emitting alot of power
May 29 16:08:06 <arcanescu> it will conk it out anyway regardless....
May 29 16:08:20 <riskable> arcanescu: The problem *starts* with packet loss but then becomes 100% loss yet if I look at the output of 'iwconfig wlan0' it still shows as connected and there's nothing in dmesg to indicate there's a problem
May 29 16:08:39 <arcanescu> riskable: are you using this with your PC or the bone?
May 29 16:08:40 <riskable> I'm chatting over this same wifi AP right now :)
May 29 16:08:46 <riskable> arcanescu: With the bone
May 29 16:08:55 <riskable> I should try it on my PC though...  Good idea
May 29 16:08:57 <arcanescu> try using it with your standard pc... and try a pc to pc ping
May 29 16:09:21 <arcanescu> connect them toghther and send ping.... to see if there is some driver issue
May 29 16:10:18 <arcanescu> if the problem still presists maybe the unit is at fault ... maybe manufacturing fault
May 29 16:10:20 <stuk_gen> found the problem is this:http://osdir.com/ml/beagleboard/2012-05/msg01056.html
May 29 16:12:32 <Sh0rtWave> Hrm, I think I do have a floating ground problem
May 29 16:12:43 <Sh0rtWave> I'm noticing that my USB->Serial eventually stops being able to tx data.
May 29 16:12:55 <riskable> Hmm...  Seem to be having problems with the USB wifi dongle in Ubuntu too
May 29 16:13:03 <Sh0rtWave> that is, the TX led on it stops flashing even when I'm sending data and I know it works.
May 29 16:14:01 <arcanescu> riskable: time for a new unit :)
May 29 16:14:13 <riskable> arcanescu: Yeah, probably.  Not done testing though
May 29 16:14:14 <arcanescu> it cost how much?
May 29 16:14:19 <riskable> $7
May 29 16:14:20 <riskable> hehe
May 29 16:14:34 <arcanescu> :) its only fair to get a new one
May 29 16:14:53 <riskable> That's why I was asking
May 29 16:14:54 <arcanescu> does it show the same packetloss problem?
May 29 16:14:59 <riskable> No, this is different
May 29 16:15:05 <riskable> Won't associate with my AP
May 29 16:15:22 <arcanescu> does it see it though? .... and the signal strength?
May 29 16:15:45 <riskable> arcanescu: Doesn't see anything, really
May 29 16:16:07 <arcanescu> hmmmm
May 29 16:16:48 <riskable> OK, it works now
May 29 16:16:58 <riskable> I re-plugged it and let Network Manager deal with it this time
May 29 16:16:59 <arcanescu> no packet drop?
May 29 16:17:07 <riskable> I thought that might be the problem (NetworkManager)
May 29 16:17:14 <riskable> Testing packet drop now...
May 29 16:17:19 <arcanescu> Ok
May 29 16:17:25 <riskable> 38 packets transmitted, 38 packets received, 0% packet loss
May 29 16:17:40 <riskable> So the problem is on the 'bone :(
May 29 16:18:22 <arcanescu> keep it going
May 29 16:18:32 <arcanescu> for over a min where you mentioned it crashed
May 29 16:20:11 <arcanescu> now if it doesnt crash look at iwconfig settings that the NetworkManager has done. Then try to replicate them on the Bone
May 29 16:20:27 <riskable> Well, it ran fine for over a minute so I stopped.  Then I let it sit for a while unused.  Now when I'm trying to use it it won't send packets.  So maybe the problem is with the sleep/power save
May 29 16:20:48 <arcanescu> hmmmm
May 29 16:21:03 <arcanescu> try the same test with bone.... unplug/plug send packets
May 29 16:21:26 <riskable> Could be my router too...  I'm getting strange errors there
May 29 16:21:40 <riskable> ath: Failed to stop TX DMA in 100 msec after killing last frame
May 29 16:21:54 <arcanescu> hmmmm....
May 29 16:21:55 <riskable> That's what my router says after I start using this dongle...  Doesn't normally say that
May 29 16:22:39 <riskable> After doing *nothing* it just came back and started working again
May 29 16:23:03 <arcanescu> dmesg | grep -i ath
May 29 16:23:19 <jay6981> that's pretty damning to the hardware
May 29 16:23:42 <aholler> try the newest firmware
May 29 16:24:09 <riskable> Ahh, not this is interesting:  If I ping the IP assigned to the dongle from the router it goes fine--seemingly indefinitely.  However, if I try to ping the router from the dongle it will go for a bit then stop working altogether
May 29 16:24:16 <riskable> s/not/now
May 29 16:25:05 <thurbad> do you have ping on the router enabled? most routers disable ping responses as a security measure by default
May 29 16:25:17 <riskable> Yeah I have ping enabled
May 29 16:25:24 <arcanescu> i was just going to say that
May 29 16:25:25 <riskable> I built this router myself :)
May 29 16:25:30 <arcanescu> oh okay
May 29 16:25:39 <riskable> I can ping the router from the regular wifi just fine
May 29 16:25:41 <arcanescu> now we know the problem :)
May 29 16:25:46 <arcanescu> :P
May 29 16:25:53 <arcanescu> what firmware are you using on your router?
May 29 16:25:54 <riskable> I'm going to disconnect my regular wifi.  I might lose IRC
May 29 16:25:57 <arcanescu> open wrt?
May 29 16:26:01 <riskable> Whatever comes with Ubuntu 12.04
May 29 16:26:10 <arcanescu> hmmm
May 29 16:26:12 <riskable> ...and whatever is in the Angstrom build (latest)
May 29 16:26:24 <riskable> I believe they're the same.  Let me double-check though
May 29 16:26:29 <arcanescu> im not sure what angstrom has
May 29 16:27:00 <riskable> yeah they're the same
May 29 16:27:16 <arcanescu> connect up the module to bone
May 29 16:27:19 <arcanescu> and ping from router
May 29 16:27:26 <arcanescu> see if it goes indefinate
May 29 16:31:03 <arcanescu> ath: Failed to stop TX DMA in 100 msec after killing last frame > is a known bug https://bugs.launchpad.net/ubuntu/+source/linux/+bug/736171
May 29 16:32:25 <riskable> My router isn't running Ubuntu
May 29 16:32:31 <riskable> It's running OpenWRT
May 29 16:34:35 <arcanescu> https://dev.openwrt.org/ticket/8446 still known problem
May 29 16:35:09 <riskable> When connected to the 'bone, pinging from the router to the 'bone has the packet loss issue
May 29 16:35:51 <riskable> Though reading that, I'm going to update my OpenWRT image.  I haven't updated it in over a year :)
May 29 16:36:48 <arcanescu> :) it might fix it
May 29 16:39:47 <riskable> I hope so
May 29 17:35:46 <angs> I follow the instruction here http://ladyada.net/products/beaglebone/wifi.html all goes fine however, after executing "root@beaglebone:~# systemctl restart connman.service" the bone doesnot connect to the access point, there is no net_addr for wlan0 interface
May 29 17:36:00 <angs> how should I proceed?
May 29 17:36:24 <riskable> angs: You using my image?
May 29 17:36:49 <riskable> ..or default?
May 29 17:36:54 <angs> no I tried first koen's image that he gave
May 29 17:36:59 <riskable> OK, then just reboot
May 29 17:37:00 * mranostay pokes _troll_ 
May 29 17:37:06 <riskable> Mine didn't work until I rebooted that first time
May 29 17:37:12 <riskable> Actually, I might have had to power off and on
May 29 17:37:15 <angs> 2012.05.24.img.xz
May 29 17:37:52 <angs> rebooting
May 29 17:40:03 <riskable> It also takes like 10-30 seconds after you can login before it will associate with your AP and get an address
May 29 17:40:10 <angs> it doesn't work, I dont see any problem on dmesg http://pastebin.com/KSSbcNAS
May 29 17:40:23 <riskable> Did you load the firmware package?
May 29 17:40:29 <angs> yes
May 29 17:41:17 <angs> I did exactly what is written on that page
May 29 17:41:27 <riskable> That looks like a good dmesg
May 29 17:41:53 <riskable> Does your dongle have a light on it?
May 29 17:42:04 <angs> it has a constant green light
May 29 17:42:15 <riskable> That means it is powered on and at least sort of working :)
May 29 17:42:24 <angs> good news :)
May 29 17:42:48 <riskable> Paste your conman settings and wifi.config
May 29 17:42:51 <angs> once I did ifconfig wlan0 up, then it stucked whenever I type ifconfig. now I am using another SD card
May 29 17:43:04 <riskable> Yeah, I had that problem a few times
May 29 17:43:09 <riskable> The power off/on fixes that one
May 29 17:44:07 <riskable> If you don't use conman you'll get odd rfkill problems
May 29 17:44:30 <angs> var/lib/connman/wifi.config        > http://pastebin.com/3Nk41SgR
May 29 17:45:11 <angs> n
May 29 17:46:04 <angs> settings > http://pastebin.com/wpJGW4xK
May 29 17:48:15 <angs> I was fine till "systemctl restart connman.service", then the bone has not get any IP address after the restart
May 29 17:53:16 <angs> it also stuck  when I type "opkg install wireless-tools"
May 29 17:55:09 <riskable> All your settings look good
May 29 17:55:27 <riskable> If you reboot you shouldn't have to restart conman...  It should come up at boot
May 29 17:55:47 <riskable> I'm going to be disconnecting for a few min
May 29 17:55:51 <riskable> Be back in a bit
May 29 17:55:56 <angs> ok
May 29 18:16:54 <koen> angs: wireless-tools is deprecated, use iw
May 29 18:17:30 <koen> which is why iw is included by default and iw isn't
May 29 18:18:36 <_av500_> koen: iw is and is not duality?
May 29 18:21:25 <ogra_> to iw or to not iw, thats the hamlet
May 29 18:21:36 * mranostay waves to _av500_ 
May 29 18:23:09 <_av500_> ogra_: to con a man into connmann
May 29 18:23:54 <ogra_> haha
May 29 18:27:09 <angs> is there any bug? when I type ifconfig it stucks
May 29 18:27:41 <mranostay> angs: spray some WD-40 on it
May 29 18:28:38 <angs> :)
May 29 18:52:14 <djlewis> angs: then if it gets too unstuck, put some duct tape on it.
May 29 21:09:02 <Petar> hello
May 29 21:09:31 <Guest84600> o jave question aabout kernel build for beagleboard
May 29 21:10:54 <Guest84600> i downloaded stable-kernel i i runned script ./build_kernel.sh
May 29 21:11:34 <Guest84600> now it is over, how to deploy it on SD now ?
May 29 21:15:51 <Guest84600> any1 alive ?
May 29 21:16:19 <serekson> look in the tools folder
May 29 21:16:20 <djlewis> only the dead living here ....
May 29 21:17:40 <Guest84600> yes, i tried install_image.sh, but it keeps saying that i need to run vuild_kernel.sh first
May 29 21:18:03 <Guest84600> *build_kernel.sh
May 29 21:18:30 <serekson> did it have an error?
May 29 21:18:39 <Guest84600> nope
May 29 21:19:12 <Guest84600> build_kernel.sh did not have error
May 29 21:20:08 <serekson> does KERNEL/arch/arm/boot/zImage exist?
May 29 21:20:41 <Guest84600> yes
May 29 21:21:11 <Guest84600> shall i try install from that folder ?
May 29 21:21:12 <serekson> well, that error in the script means that it wasn't found
May 29 21:22:08 <Guest84600> there is install script in the folder KERNEL/arch/arm/boot/zImage
May 29 21:22:38 <serekson> I would read it first
May 29 21:22:39 <Guest84600> there is install script in the folder KERNEL/arch/arm/boot/ sorry
May 29 21:23:43 <Guest84600> yes, i ddont think it would be useful
May 29 21:24:30 <Guest84600> how to correct path in install_image in stable-kernel/tools
May 29 21:26:18 <serekson> its might be a permissions thing
May 29 21:26:22 <serekson> since you said the file was there
May 29 21:36:04 <Guest84600> i tried with sudo to run the script, but again same error
May 29 21:36:20 <Guest84600> Using: Cross Compiler ERROR: Please run build_kernel.sh before running this script...
May 29 22:11:52 <riskable> I am happy to report that after updating my ath9k-based OpenWRT to a newer ROM my rtl8192cu-based USB wifi adapter is working much better
May 29 22:12:12 <riskable> Still getting 50% packet loss but at least it stays connected and usable the whole time :)
May 29 22:13:27 <KeatonT> 50% packet loss
May 29 22:13:28 <KeatonT> !
May 29 22:13:30 <KeatonT> that's insane
May 29 22:13:32 <raymohi> Owww
May 29 22:14:06 <raymohi> Most I ever see even at 400+ feet is 10%
May 29 22:16:28 <KeatonT> yea
May 29 22:17:54 <Russ> you have noise?
May 29 22:55:21 <jtr001-UCSD> Hello all,  I am currently trying to use the beaglebone to create an oscilloscope spectrum analyzer.  I want to be able to convert the analog singal into a digital signal, display the signal and the FFT of the signal.  My first approach was to put matplotlib and wxPython on the board to help with the GUI.  However, I am finding this very difficult, does anyone have a suggestion as to how I should go about this?
May 29 23:13:59 <riskable> For reference, the packet loss is caused by the driver
May 29 23:14:06 <riskable> ...not due to interference or anything like that
May 29 23:14:11 <riskable> Also, the card is a POS
May 29 23:14:28 <riskable> Wait, not a "card"...  It's a USB dongle the size of a fingernail
May 29 23:14:36 <riskable> You get what you pay for... $7 in this instance
May 29 23:24:42 <thurbad> if it's a micro sized dongle, what does it do for an antenna?
May 29 23:25:23 <KeatonT> thurbad the circuit is actually in the part of the usb that goes into the slot.
May 29 23:25:32 <KeatonT> The part that sticks out is the antenna
May 29 23:26:05 <thurbad> crazy talk!
May 29 23:26:40 <mdp> fix it in s/w
May 29 23:26:52 <thurbad> heh
May 30 00:28:20 <mranostay> mdp: the endless cycle between hw and sw guys :)
May 30 00:28:53 <mranostay> although you can't magically software encode a pull down resistor. :)
May 30 00:30:24 <mdp> lies!!!
May 30 00:35:30 <beagle_noob> I am trying to build matplot lib with command "python setup.py build" and it returns this error. "error: command 'arm-angstrom-linux-gnueabi-g++' failed with exit status 1"
May 30 00:35:40 <beagle_noob> any ideas?
May 30 00:39:33 <beagle_noob> more complete error: "/usr/lib/gcc/arm-angstrom-linux-gnueabi/4.5.4/../../../../arm-angstrom-linux-gnueabi/bin/ld: this linker was not configured to use sysroots collect2: ld returned 1 exit status error: command 'arm-angstrom-linux-gnueabi-g++' failed with exit status 1"
May 30 01:10:24 * mranostay hides from panto 
May 30 01:11:17 <KeatonT> o_O
May 30 01:14:44 <KeatonT> I find it hard to believe that the bone does not have an onboard temperature sensor.
May 30 01:14:48 * panto hunts down mranostay 
May 30 01:15:04 <panto> KeatonT, why should it?
May 30 01:15:34 <panto> the whole temperature sensor on a cpu bit is a fairly recent development (<10y)
May 30 01:15:34 <KeatonT> idk protection?
May 30 01:16:04 <panto> you don't need that if you design the system to operate properly in all temperature ranges even at full load
May 30 01:16:11 <agmlego> KeatonT: Well, there is a difference between a *user-accessible* onboard thermal sensor and a thermal protection sensor.
May 30 01:16:17 <agmlego> The latter does not need to be the former.
May 30 01:17:07 <KeatonT> ah
May 30 01:24:08 <KeatonT> oh well I'm buying some temp sensors.
May 30 01:38:42 <riskable> Argh, I wish Comcast would enable dual-stack IPv6 in my area already
May 30 01:39:17 <KeatonT> dual-stack?
May 30 01:39:18 <riskable> Four years ago I built my first custom OpenWRT image ready-to-go with IPv6 support.  I've rebuit it probably over a hundred times now...  Still waiting for the IPv6 Internet to be ready for me
May 30 01:39:42 <riskable> Every time I'm in that "make menuconfig" I go through all the extra IPv6 stuff--wishful thinking apparently
May 30 01:39:54 <riskable> Dual-stack:  IPv4 and IPv6 simultaneously
May 30 01:40:14 <riskable> Single-stack IPv6 would mean you have no IPv4 network at all
May 30 01:40:58 <riskable> My home network USED to be single-stack IPv6 but then I got a Windows XP laptop from the office and Cisco's VPN concentrator.
May 30 01:41:19 <riskable> Together that combination required that I re-configure IPv4 on my entire network
May 30 01:41:29 <KeatonT> :(
May 30 01:42:06 <riskable> Everyone asks me, "How did you know how to connect to which device when it is all IPv6?  The addresses are all like, crazy long!"
May 30 01:42:16 <KeatonT> lol
May 30 01:42:20 <beagle_noob> Has anyone put matplotlib on the beaglebone sucessfully?
May 30 01:42:26 <riskable> My response is twofold:  "Ever heard of zeroconf/avahi/rendezvous?"
May 30 01:42:57 <riskable> ...and I also make sure that all my hostnames get auto-registered in DNS as hostname.lan
May 30 01:43:13 <riskable> So if hostname.local (avahi) doesn't work, hostname.lan will
May 30 01:43:52 <riskable> beagle_noob: You having problems getting matplotlib installed?
May 30 01:44:08 <beagle_noob> Yes, I am
May 30 01:44:21 <riskable> Is there no ipk for it?
May 30 01:44:37 <beagle_noob> Where would i look for that? I have the .tar.gz file
May 30 01:45:22 <riskable> BTW:  python-matplotlib works awesome inside of Gate One...  You can print our graphs and whatnot to stdout and they'll appear in the terminal!
May 30 01:45:34 <riskable> beagle_noob: Let me see if I can get it to compile :)
May 30 01:45:58 <beagle_noob> typing in "opkg install python-matplotlib" returns "Unknown package 'python-matplotlib'."
May 30 01:46:52 <riskable> Yeah, there's no ipk for that either :)
May 30 01:47:13 <riskable> I planned to make an ipk for ipython I guess I might as well make one for matplotlib too
May 30 01:48:25 <beagle_noob> When I try to install with setup.py -> "python setup.py build" it spits out an error " this linker was not configured to use sysroots" next line is " error: command 'arm-angstrom-linux-gnueabi-g++' failed with exit status 1"
May 30 01:48:45 <beagle_noob> Can this command not be used in Angstrom?
May 30 01:48:51 <riskable> Yeah, it needs to be compiled and you don't have a compiled on the beagle itself
May 30 01:49:00 <riskable> s/compiled/compiler
May 30 01:49:05 <beagle_noob> Is it possible to get one?
May 30 01:51:10 <beagle_noob> Well...I really just wanted matplotlib to plot data that has been read from the analog pins.  Is there another way to go about this?
May 30 01:52:19 <riskable> Yeah, you could write your own implementation of matplotlib
May 30 01:52:32 <riskable> ...but just give me a few minutes to play around to see if I can't make a .bb for matplotlib
May 30 01:58:30 <beagle_noob> Okay will do.
May 30 02:00:09 <riskable> OK I just made a matplotlib_1.1.0.bb file...  Trying to bitbake it now
May 30 02:00:12 * riskable crosses fingers
May 30 02:03:23 * riskable is fixing some minor configuration items and typos...
May 30 02:05:16 * riskable twiddles thumbs waiting for bitbake
May 30 02:05:52 <riskable> Ugh, bad checksum on the LICENSE.  I always forget that one!
May 30 02:07:47 <beagle_noob> O_O
May 30 02:09:10 <riskable> Ugh, this is going to take longer than a few minutes
May 30 02:09:25 <riskable> Check back here tomorrow...  I'll see if I can get this put together by then
May 30 02:09:33 <riskable> No promises though
May 30 02:09:46 <riskable> I need to learn how to do dependencies with .bb files...  Don't know how to deal with that yet
May 30 02:10:15 <riskable> matplotlib requires numpy...  Which is available already in the recipes but I need to figure out how to point the matplotlib.bb at the numpy build dir to make it build OK
May 30 02:11:14 <beagle_noob> ahh ok thanks for all your help
May 30 02:11:24 <riskable> Time for me to hit the sack.  Hopefully I'll get enough caffeine tomorrow to get the python-matplotlib out the door *and* finish what I need to get done with Gate One
May 30 02:11:36 <beagle_noob> laters
May 30 02:11:37 <riskable> Have a good one
May 30 02:11:40 <beagle_noob> you too
May 30 02:13:09 <agmlego>  /away Away - sleeping
May 30 02:13:15 <agmlego> ...stupid spaces.
May 30 02:14:51 <riskable> As I was brushing my teeth I realized I should paste my .bb in case someone wants to finish it...
May 30 02:15:52 <riskable> Here it is:  https://gist.github.com/2832853
May 30 02:16:20 <riskable> All that it needs is something to tell bitbake that 'python-numpy' is a dependency and to use it (however that works--I don't know otherwise I would've done it)
May 30 02:16:29 <riskable> Anyway, going to sleep for real this time :)
May 30 02:19:51 <beagle_noob> thanks riskable
May 30 02:52:09 <KeatonT> Lots of stuff to do.
