  • [01:12:14] <emeb> I've found some significant issues with the am33xx pin muxing code.
  • [01:12:43] <emeb> the GPIO_TO_PIN() macro basically doesn't work - returns the wrong pin index.
  • [01:13:44] <emeb> and the am33xx_muxmodes[] array leaves most GPIO pins undefined so you can access them by name.
  • [01:14:35] <emeb> and the mux data structure doesn't initialize the GPIO indicies, do the kernel GPIO driver can never allocate pins.

  • [01:43:45] <emeb> wow - lotta typos in the previous...
  • [01:44:20] <emeb> Anyway - this is all with the ti33x-psp-3.1 that's currently in OE.
  • [01:44:33] <jay6981> that must be why you can't remux a pin?

  • [01:53:44] <jay6981> i'm curious about those differences??? gotta dig into OE some I suppose
  • [01:55:26] <emeb> It's actually pretty easy.
  • [01:55:52] <emeb> pretty much plug n chug - just follow the directions. If all you want is the kernel it's even easier.

  • [02:18:56] <josephalevin> Anyone know of docs on how to read/write to bone pins on ubuntu?
  • [02:19:35] <zumi> for those who got a bone, did you get two different SD cards?
  • [02:19:47] <josephalevin> Yes, I did.
  • [02:20:33] <josephalevin> One with Angstrom, Cloud9ide, and gateone
  • [02:20:49] <josephalevin> The other had the Texas Inst. sdk.
  • [02:20:56] <josephalevin> Both were bootable on the bone.
  • [02:20:59] <zumi> is the other just a base TI image? that is what I am assuming
  • [02:21:50] <josephalevin> Yeah, I made the mistake of putting in the TI image and forgetting a few days later. Couldn't figure out why nothing in the bone docs was showing up.
  • [02:22:04] <jay6981> josephalevin: the gpio pins?
  • [02:22:46] <zumi> ok, makes sense. I don't have a working linux build yet, so I am flying somewhat blind.
  • [02:22:47] <josephalevin> jay6981: yes, I think so. For starters I just want to blink an led in ubuntu.
  • [02:22:58] <zumi> actually about to boot it for the first time now
  • [02:23:16] <jay6981> josephalevin: this might help http://www.mjmwired.net/kernel/Documentation/gpio.txt

  • [04:22:51] <emeb> if it's outputting a 0V digital "0" you can dump 8mA into it.

  • [13:21:03] <dwery> hi, just got my bone... I'm trying to find the kernel source that was used for the stock kernel that comes on the SD. the website refers to https://github.com/beagleboard but it seems that it isn't the correct one. Anyone got a clue?
  • [13:24:15] <tlab> did you install the ti sdk?
  • [13:26:58] <dwery> tlab: No, I'd just like to download the sources on thei own, no strings attached
  • [13:29:48] <tlab> well it contains the stock kernel config
  • [13:30:19] <dwery> Is the TI kernel for thei EVM the same used for the bone?

  • [13:30:49] <tlab> I think so
  • [13:31:23] <dwery> the bone has a few more features, like the led driver, that is bone specific.. so I guess they should have patches for that somewhere
  • [13:31:50] <tlab> there is an option in the config to select beaglebone
  • [13:32:05] <dwery> nice, I'm going to get it. do you have a link?
  • [13:32:19] <tlab> the sdk?
  • [13:32:21] <dwery> yes

  • [13:42:19] <dwery> uhm.. no partition with that name as far as I can see

  • [16:58:38] <Jordan> hi
  • [16:58:57] <Jordan> Does anyone know what's changed for the new angstrom distribution?
  • [16:59:10] <emeb> since when?
  • [16:59:10] <Jordan> Does anyone know what's changed for the new angstrom distribution?
  • [16:59:44] <emeb> which platform?
  • [17:00:56] <jay6981> well, first the earth cooled
  • [17:01:01] <jay6981> then the dinosaurs came
  • [17:01:06] <jay6981> but they got too big and fat
  • [17:01:23] <koen> The autotropes began to drool
  • [17:01:35] <koen> Neanderthals developed tools
  • [17:02:01] <Jordan> For the beaglebone...
  • [17:02:02] <Jordan> Angstrom-Cloud9-IDE-eglibc-ipk-v2011.12-core-beaglebone-2011.12.26.img.gz
  • [17:04:51] <emeb> Presumably it's newer, shinier, includes the latest fixes to everything and will make you happier and wealthier.
  • [17:05:16] <emeb> specific details are left as an exercise for the user.
  • [17:05:48] <jay6981> sounds like apple's release notes
  • [17:05:51] <emeb> And please ignore/forgive any new or pre-existing bugs.
  • [17:06:18] <jay6981> emeb: you get anywhere with your gpio interrupt issue?
  • [17:06:37] <emeb> jay6981: just getting started again. Gotta relax sometime. :)
  • [17:06:43] <jay6981> hehe
  • [17:08:05] <Jordan> Thanks emeb...release notes would be nice, sigh
  • [17:09:07] <emeb> Jordan: true, but we take what we get and are thankful!

  • [17:10:46] <koen> Jordan: bugfixes and updates, nothing eath shattering
  • [17:11:36] <Jordan> okay, thanks. I'm trying to get a wireless dongle working. Does anyone have any idea if this would be easier if I got an ubuntu distrib up and running on my Bone? Sorry if it's an overly general question
  • [17:12:05] <Jordan> It seems like a lot of basic utils are missing from Angstrom...I just installed emacs (took an hour to build), and would like to get x11 stuff installed as well
  • [17:12:08] <koen> nothing is easier with ubuntu
  • [17:12:13] <koen> except being slow and bloated
  • [17:12:14] * emeb had no trouble getting a USB wifi dongle working on Beagleboard w/ Angstrom a few years ago.
  • [17:12:15] <jay6981> heh
  • [17:12:41] <rcn-ee> koen, just 'bloated'.. the armhf image is out. .;)
  • [17:12:42] <emeb> but then koen helped out on that
  • [17:13:04] <Jordan> do you know if it's possible to get "apt-get" for angstrom? I'm new to linux...this looks like the easiest way to install a lot of packages
  • [17:13:06] <koen> any problems will be kernel related and there are no ubuntu developers working on bone kernel, only rcn-ee
  • [17:13:24] <koen> Jordan: ln -sf /usr/bin/opkg /usr/bin/apt-get
  • [17:13:35] <emeb> lol
  • [17:13:50] <jay6981> a new abi; yay!
  • [17:14:15] <koen> rcn-ee: still slow, since you can't use sgx with hf currently
  • [17:15:37] <rcn-ee> yeap, correct about no sgx.. and still lots of packages broken.. but for a minimal it's a nice bump over armel..

  • [17:19:48] <koen> rcn-ee: that was almost 3 years ago
  • [17:20:11] <koen> 2 weeks ago I get asked "what's that hf about?"

  • [17:20:56] <rcn-ee> that's funny..
  • [17:21:48] <rcn-ee> thinking about, it you could probally use the multarch stuff in precise, to let the sgx use softfp, 'armel' bits, so your sgx application would be as slow as armel, but the rest of the system would be armhf.. and more stuff to download/install..
  • [17:22:02] <rcn-ee> so 2x bloated.. ;)

  • [17:29:56] <koen> no neon, vfp16
  • [17:30:27] <koen> it all boils down to dpkg not supporting freeform architecture fields
  • [17:30:45] <koen> so ubuntu needs to pick the lowest common denominator
  • [17:31:08] <jay6981> interesting
  • [17:31:08] <koen> which suck, since marvell and nvidia were being stupid by not using NEON
  • [17:31:13] <koen> +s somewhere
  • [17:33:35] <rcn-ee> even with armhf, precise/sid is no neon , vfp16.. "--with-fpu=vfpv3-d16"...

  • [19:30:42] <emeb> re - stacking. no arguments.

  • [19:32:00] <emeb> ie - with the gpio-based encoders my hardware cost is just the encoder itself. Even the pullups are on-chip.

  • [20:55:38] <Jordan> hi, does anyone have any experience getting USB wifi's to work?
  • [20:55:55] <Jordan> I keep getting a timeout on authenticating
  • [20:59:59] <zumi> humidifier is a great idea, unlikely to get one at the office though
  • [21:00:07] <zumi> this place is too large
  • [21:02:35] <djlewis> i know better, but . . . Jordan , you can use the wifi tools to see whats up, iwconfig is one
  • [21:04:28] <koen> iwconfig is obsolete, better use iw
  • [21:05:00] <Jordan> I'm unable to assocaite, but I am getting output out of iwconfig (singal strength, etc)
  • [21:05:17] <Jordan> Does this imply my USB device is indeed supported?
  • [21:05:27] <Jordan> I just turned off encryption too, in case i had WPA setup incorrectly
  • [21:05:37] <jay6981> can you associate to an open AP?
  • [21:05:51] * djlewis always starts with an open AP
  • [21:05:52] <JohnBabrick_> Hello all.
  • [21:05:58] <djlewis> hi

  • [21:06:17] <Jordan> no
  • [21:06:29] <Jordan> (i assume by open, you mean i've turned encrptyion off?)

  • [21:07:18] <djlewis> my access point can be "secured" with MAC address and encryption
  • [21:07:43] <Jordan> well, i'm pretty sure this is open...just connected with my iphone without a password or MAC setup
  • [21:07:57] <Jordan> is it a problem if I have an ethernet cable plugged into the beaglebone as well?
  • [21:08:17] <Jordan> one of the guides said you should unplug the ethernet cable to setup a wifi dongle, but that seems like a catch-22
  • [21:09:07] <rcn-ee> it's probally more for helping you debug that your wifi actually has a connection.. ;)
  • [21:09:40] <JohnBabrick_> I am just starting out on Beagleboard and Angstrom. I have gotten the cross toolchain working on the host machine and a console only image running on the Beagle. I tried running Arora browser with the -qws option and it worked - sort of. The USB keyboard does not seem to operate - no way to enter text. Also, there is a black box across the menu bar - but moving the mouse over the menu items allows them to work. Any ideas on the keyboard?

  • [21:13:39] <rcn-ee> bummer, figured most places would have that off since new years is on a sunday..
  • [21:14:17] <Jordan> if I'm getting singal strength from iwconfig, does that mean I don't need to place aroudn with NDISWRAPPER at least, and that my USB dongle is supported at least?
  • [21:14:34] <djlewis> I dont get paid holidays or vacation or sick days
  • [21:15:09] <djlewis> Jordan: dmesg and iwconfig should tell you if your wifi dongle is working.

  • [22:20:10] <JohnBabrick_> hi
  • [22:20:20] <wag> i've just gotten a beaglebone, and i did a software upgrade.
  • [22:20:53] <wag> now i can no long access the beaglebone. not by the serial console nor ssh (no browser).
  • [22:21:37] <wag> i was upgrading the stock angstrom that comes with the beaglebone.
  • [22:22:03] <djlewis> was the "opkg upgrade" ever fixed?
  • [22:22:11] <woglinde> djlewis no
  • [22:22:21] <djlewis> it should be disabled
  • [22:22:23] <woglinde> failing was a hot topic yesterday
  • [22:22:45] <djlewis> it gets lots of newbies
  • [22:23:02] <wag> mmm. well, i've gotten myself messed up trying "opkg upgrade"
  • [22:23:12] <djlewis> I last tested it, on purpose, back in 2.6.29 days and it was broke.
  • [22:23:21] <wag> can i reinstall an image on that sd card in a simple way?
  • [22:23:56] * djlewis recommends keeping master card and purchasing fresh SD's for new testing
  • [22:24:13] <djlewis> but it is irrelevant for you now :(
  • [22:24:21] <wag> yeah.
  • [22:24:56] <djlewis> woglinde: was disabling upgrade at the dnload site an option discussed?
  • [22:25:41] <djlewis> wag: i am not familiar with the beaglebone requirements

  • [22:37:30] <TheBurrito> anyone have any references to tricks for getting sound to work with C4?
  • [22:38:07] <thurbad> what are you using that's not playing sound?
  • [22:39:06] <TheBurrito> aplay
  • [22:39:12] <TheBurrito> trying to play a wav file
  • [22:39:32] <TheBurrito> also, trying to use festival crashes with a "close" message, but about 300 more e's
  • [22:40:17] <TheBurrito> I have ubuntu natty on it, installed alsa, turned on the levels that the suggestions all over say to
  • [22:40:52] <rcn-ee> TheBurrito, there was a couple things missing from Natty, which kernel (uname -a)
  • [22:41:11] <TheBurrito> Linux omap 3.1.4-x6 #1 SMP Sun Dec 4 17:22:57 UTC 2011 armv7l armv7l armv7l GNU/Linux
  • [22:41:50] <TheBurrito> in alsamixer I notice there's nothing listed next to Chip:
  • [22:42:24] <rcn-ee> that kernel should have working audio... it's just weither userspace's aplay knows how to set it up..
  • [22:43:11] <rcn-ee> does: aplay --list-devices (show anything useful)
  • [22:43:21] <TheBurrito> is there documentation somewhere I can pour through?
  • [22:43:35] <TheBurrito> card 0: omap3beagle [omap3beagle], device 0: TWL4030 twl4030-hifi-0 []
  • [22:43:35] <TheBurrito> Subdevices: 0/1
  • [22:43:35] <TheBurrito> Subdevice #0: subdevice #0
  • [22:45:11] <rcn-ee> that looks good so far... i don't remember the trick in ubuntu, audio is something i never test..
  • [22:47:11] <rcn-ee> TheBurrito, alsa just might be broken in natty: looking at https://bugs.launchpad.net/ubuntu/+bug/651302

  • [23:16:17] <nick5000> Hi there.... me again with a short question. Anybody awake here....? The question is: Can I extract the update Angstrom image to the SD card if it is mounted via USB? Or do I need to get a SD card reader?
  • [23:18:46] <nick5000> Same question here, maybe better here: (BeagleBone) Can I extract the update Angstrom image to the SD card if it is mounted via USB? Or do I need to get a SD card reader?
  • [23:19:36] <nick5000> (with mounted I mean auto-mounted because the BeagleBone is connected via USB)
  • [23:20:54] <djlewis> A SD card reader makes life so much easier
  • [23:22:08] <nick5000> yeah, but is kinda hard to get at midnight ;)
  • [23:23:30] <nick5000> the question is whether zcat .. >/dev/... works or will corrupt something... what do you think/know, djlewis ?
  • [23:24:28] <djlewis> if you are talking about replacing your file system on the SD while the bone is running, I dont think you can
  • [23:25:03] <djlewis> most laptops and desktops since past several years have a SD reader built inl.
  • [23:25:20] <nick5000> ok, that was what I thought as well. I don't think that the problem is the running system, but I don't know whether the usb connection gives a 1:1 access to the card.
  • [23:25:59] <nick5000> unfortunately Apple decided in 2008 that SD cards are still meant to be "the future" but not "the present" ;)
  • [23:26:08] <djlewis> oh.
  • [23:26:48] <nick5000> but life does not depend on this update - for now ;)
  • [23:27:57] <thurbad> the SD on my macbook is slower than hell
  • [23:28:05] <djlewis> i'm leaving the office too due to a lack of interest..
  • [23:29:12] <thurbad> have to use a external reader to get speeds beyond class 4
  • [23:30:05] <nick5000> thx djlewis, bye
