**** BEGIN LOGGING AT Wed Jul 25 02:59:58 2012 Jul 25 03:15:18 does anyone know if the beaglebone can run the new 3.5 kernel? Jul 25 03:15:48 hehe Jul 25 03:16:18 o; Jul 25 03:18:13 is that a no? Jul 25 07:09:56 Hi! I'm facing some problems trying to modify the kernel to get an ads117x (alsa asoc) codec running on beaglebone (ångström 2012.05). Is anyone into this? Jul 25 07:10:34 * _av500_ is into 80's glam rock Jul 25 07:10:44 <_av500_> still, you could state the problem Jul 25 07:11:21 *metal* Jul 25 07:17:07 i took the codec driver as-is and modified the platform driver which was a tlv320aic3x. Since I've done this changes, soundcard and codec is not recognized any anymore Jul 25 07:25:09 there are some points which I'am quite unsure how to handle, especially dapm. In the new ads117x codec is nothing of dapm mentioned at all. How does this work? Is it necessary to initialize a snd_soc_dapm_route audio_map[] in the platform driver? Jul 25 07:53:26 Also looking at codec stuff. Right now I'm trying to figure out how to get Angstrom to build a 3.2.23 kernel instead of a 3.2.18 ... Jul 25 07:55:01 It has something to do with: koenkooi pushed to angstrom-staging at Angstrom-distribution/meta-ti July 17, 2012 linux-ti33x-psp 3.2: update to 3.2.23 Jul 25 07:55:18 However, I can't figure out the right thing to change in the build scripts :( Jul 25 08:22:59 <_av500_> koen: heh, g+ sharing right from lkml :) Jul 25 08:33:09 _av500_: ah, I hadn't noticed that yet Jul 25 08:33:59 <_av500_> i did after I clicked your libk :) Jul 25 08:34:01 <_av500_> link Jul 25 08:35:52 Gyaaah ... I edited layers.txt to use angstrom-staging but the build system overwrote it ... Jul 25 08:57:21 Okay, so I bumped the meta-ti port line to: meta-ti,git://github.com/Angstrom-distribution/meta-ti.git,angstrom-staging,HEAD Jul 25 08:57:39 Redid the oebb.sh config dance and just started a rebuild ... Jul 25 08:57:45 Anything I missed? Jul 25 09:17:21 bsder: rm sources/meta-ti -rf Jul 25 09:18:32 koen: Sorry, I forgot to mention that. I did remove that directory when the config scripts whined about versions not being the same. Jul 25 09:19:29 koen: Thanks for the reminder though. Jul 25 10:00:45 Much better -- that actually built everything an now the kernel is at the appropriate version ... Jul 25 10:01:17 Now I can try to attack the original problem of having multiple codecs on the mcASP bus ... Jul 25 10:20:21 hi folks Jul 25 10:20:50 Is there a simple way to get audio out of the beaglebone? I've tried searching the list but there doesn't seem to be much on nit Jul 25 10:24:19 I think that finding a linux-supported USB soundcard is probably the way to go. Jul 25 10:24:59 There are some mumblings about the DVI cape having audio, but that seems to involve quite a bit of extra work ... Jul 25 10:37:52 bsder: dvi+audio cape works out of the box Jul 25 10:37:58 the audio cape as well Jul 25 10:38:07 I wonder why people keep saying it doesn't work Jul 25 10:38:24 That's great to know ... Jul 25 10:39:19 They probably keep saying it doesn't work because Google returns lots of results talking about it not working ... Jul 25 10:39:43 That's what my opinion was based on ... Jul 25 10:39:50 hi Jul 25 10:40:05 I have one doubt Jul 25 10:40:16 Unfortunately, nobody has announced "Hey, the DVI cape works out of the box now ..." somewhere where Google will pick it up ... Jul 25 10:40:25 which is better bluetooth gps receiver or usb gps receiver ? Jul 25 10:40:57 which is better bluetooth gps receiver or usb gps receiver ? Jul 25 10:42:45 bsder: it has been stated multiple times on the google groups Jul 25 10:43:02 bsder: pretty much every time someone says "OMG AUDIO IS NOT WORKING!!!one!!" Jul 25 10:43:46 hi koen Jul 25 10:44:05 can anyone suggest me which is better bluetooth gps receiver or usb gps receiver ? Jul 25 10:45:36 koen: When I went digging through BeagleBone docs, groups, etc. it certainly wasn't clear to me. Jul 25 10:46:01 koen: I went and bought a TI TLV320AIC3254 eval kit precisely *because* I thought that ... Jul 25 10:46:25 koen: So, I spent *money* due to thinking that ... Jul 25 10:47:01 koen: So, I will go get one of those capes now. I'd rather start from a working board and add another codec rather than starting from scratch. Jul 25 10:47:50 which is better bluetooth gps receiver or usb gps receiver Jul 25 11:10:59 Hi all, I have V4l2 capture code which is using mmap() and running on beagle-xm rev.A3 but instead of tht I want to to use V4L2 user ptr method any idea for correct kernel to use v4l2 ptr for beagle Jul 25 11:20:42 koen: I just took a quick look at DigiKey, Mouser, etc. and even CircuitCo directly. It seems I can't actually *buy* any capes with audio on them. Jul 25 11:21:12 koen: That's certainly going to make for a lack of users saying "hey, audio works" ... Jul 25 11:30:52 bsder: and for users saying "hey, audio doesn't work" Jul 25 11:42:04 koen: True, but unfortunately what Google returns for "beaglebone audio" is a bunch of CircuitCo stuff that isn't out, some random TI posts, and random posts a couple of months (or more) old from people dealing with various levels of brokenness. Jul 25 11:42:34 koen: Google's algorithms to make things "relevant" are unfortunately preventing timely information from bubbling up. Jul 25 11:44:26 koen: The whole thing that got me started about the 3.2.23 kernel was that I saw your post (in late June, IIRC) and the date on my beaglebone image and said "Well, I better get up to the latest then to make things work ..." Jul 25 12:04:17 guys, i need help. I have installed OE to my ubuntu, then i have installed opencv with examples. But when i do "make all" in example package i get this error : "line 141: xdc.services.global.XDCException: xdc.PACKAGE_NOT_FOUND: can't locate the package 'dsplink.dsp' along the path:" what is that problem? (No solution found at google) Jul 25 12:07:50 I'm not getting any further to get the ads117x codec working... does anyone have experience with codecs? I modified davinci-evm and the kernel configuration to use it. the codec does appear in /sys/bus/platform/drivers/ads117x-codec. after the changes, there's no soundcar/codec anymore Jul 25 14:07:43 hi Jul 25 14:07:53 someone got python to work on the beaglebone ? Jul 25 14:08:02 whenever I try to install packages I have a weird hash error Jul 25 14:08:07 and no hashing lib is available Jul 25 14:08:24 should I recompile python from source on the beagle or is there a simpler solution ? Jul 25 14:14:52 jon1012: did you install the python hashing modules? Jul 25 15:02:40 Does the BeagleBoard power supply need to be current regulated, or only voltage regulated? Jul 25 15:03:46 taixzo: voltage regulated is enough. Jul 25 15:03:55 LetoThe2nd, thanks. Jul 25 15:47:46 say what? i have to regulate the power supply? Jul 25 15:48:07 you need a 5V regulated power supply Jul 25 15:53:07 I'm trying to figure out how to run a Beagleboard from two Lithium-Polymer batteries. Jul 25 15:54:09 taixzo: hehe, just google for "beaglejuice" and see how they do it. Jul 25 15:55:31 LetoThe2nd, they don't provide a circuit diagram, and I don't really want to buy one since I already have batteries Jul 25 22:23:33 *crickets* Jul 25 22:23:47 mranostay: those are tasty when fried Jul 25 22:24:34 only in Texas? Jul 25 22:24:43 mranostay: hehe Jul 25 22:24:53 7 years of bad luck with every bite Jul 25 22:25:38 prpplague: deep fried of course right? Jul 25 22:26:28 mranostay: more like stir fry but in a cast iron skillet Jul 25 22:27:42 ew Jul 25 22:27:57 mranostay: not so bad Jul 25 22:28:07 mranostay: kind of like popcorn Jul 25 22:28:22 then eat popcorn? Jul 25 22:28:39 mranostay: or kind of like miniture boiled crabs and you eat shell and all Jul 25 22:29:17 mranostay: hehe, we usually do it as a camping thing for the boy scouts Jul 25 22:30:14 never had that Jul 25 22:30:26 hehe Jul 25 22:30:31 * prpplague heads home for the day Jul 25 22:30:34 mranostay: later Jul 25 22:32:41 Is there a generic way to get higher timer resolution then a jiffy in a kernel driver? Jul 25 23:17:15 Any device tree experts on? Jul 25 23:17:54 I'd like to know if it's possible to make a device tree node for something like an SPI slave device defined _outside_ the SPI master device's block. Jul 25 23:18:38 Because it would seem like... the SPI master block would be in a .dtsi file for the SOC, where the SPI slave block would want to be in the board's .dts file. Jul 25 23:19:22 I don't see a good example of that in the ARM dts/ directory, of course it now occurs to me that I should check other architectures too. Jul 25 23:19:28 ugh, so my beaglebone does serial over usb just fine when I attach it in windows and use putty, but minicom, tip, cu just don't work at all :( Jul 25 23:20:19 bmercer: is your usb-to-serial device recognized? in the dmesg? /dev/ttyUSBx ? Jul 25 23:20:36 it is, it attaches as uftdi0 Jul 25 23:20:54 /dev/uftdi0 ? Jul 25 23:21:39 sorry, it's /dev/cuaU0 Jul 25 23:22:08 ok, that's a new one one me... do you have a udev rule that renames it that way on purpose? Are you using Linux? Jul 25 23:22:13 distro and version? Jul 25 23:22:16 I'm using openbsd Jul 25 23:22:50 Are you experienced with minicom? Jul 25 23:22:54 I only ask because...... Jul 25 23:23:11 no, I usually use cu Jul 25 23:23:13 It's quite a pain, and to the untrained eye, it looks like it's not working Jul 25 23:23:30 and many would call that behavior a bug, but it's been like that for years unfortunately Jul 25 23:23:45 the biggest thing is..... you need to restart minicom after changing settings Jul 25 23:23:50 well, after changing port Jul 25 23:23:53 at least Jul 25 23:23:55 ok Jul 25 23:23:57 maybe after others Jul 25 23:23:58 but Jul 25 23:24:02 you'll of course want to save it Jul 25 23:24:13 but it won't save quite the way you think it will Jul 25 23:24:17 It's quite maddening, actually Jul 25 23:24:42 It will save into the file that you currently have open (dfl by default) even if you say "save as" Jul 25 23:24:59 ok, to verify settings, 115200 8N1 Hardware Flow Control yes, Software Flow control yes Jul 25 23:25:01 I started working on fixing this at one point, but never finished :( Jul 25 23:25:06 No Jul 25 23:25:09 Flow control OFF Jul 25 23:25:26 ok Jul 25 23:25:35 115200 8N1 <= yes Jul 25 23:25:42 I also have ttyU0 and ttyU1 or cuaU0 and cuaU1 Jul 25 23:26:01 I'm not a BSD guy, so I can't say for sure which one to use Jul 25 23:26:03 but Jul 25 23:26:13 you could unplug, look at /dev, re-plug, look at dev, and see what's different Jul 25 23:26:24 or look at dmesg Jul 25 23:26:25 I get 0 and 1 on both Jul 25 23:26:42 so your device is creating both 0 and 1? Jul 25 23:26:47 yup Jul 25 23:26:50 in that case, try the other one :) Jul 25 23:27:11 you have been very helpful, thank you Jul 25 23:27:39 no prob Jul 25 23:28:23 I still don't get anything :( Jul 25 23:28:30 and minicom says "Offline" Jul 25 23:28:51 don't worry about "offline" Jul 25 23:29:02 I think that more relates to the phone dialer function Jul 25 23:29:48 yeah, just checked, mine shows "Offline" too Jul 25 23:39:28 regarding my device tree question, I see it now. Anyone interested can see omap4-panda.dts and look at the i2c1 section that relates to i2c1 in omap4.dtsi Jul 26 00:25:44 hey purple Jul 26 00:31:26 mranostay: hey hey Jul 26 00:31:33 * prpplague drinks a beer instead of going to the gym this evening Jul 26 00:31:38 my nose is still hurting, so no gym tonight Jul 26 00:31:43 prpplague: i do that every evening :) Jul 26 02:01:51 I'm starting to wonder if something on openbsd's uftdi driver is messed up Jul 26 02:01:59 or usb Jul 26 02:02:23 I can see some output, enough to type root and see the command prompt to log in Jul 26 02:02:37 and whoami works, but w or top doesn't Jul 26 02:02:45 and then it requires a reset of minicom Jul 26 02:05:47 http://pastebin.com/rNzLJE4u Jul 26 02:06:05 Has anyone tried using this EEPROM for prototyping on the Beaglebone: https://www.sparkfun.com/products/525 Jul 26 02:06:54 STrRedWlf: not a good choice, limited voltage range, but can be used Jul 26 02:08:09 prpplague: Probably good enough on a perfboard and prototyping, but for a solid protoboard from Adafruit, I'll get the EEPROM listed in the docs from Element14. Jul 26 02:36:03 * mranostay hangs prpplague a beer Jul 26 02:36:07 *hands Jul 26 02:50:09 * mranostay pokes prpplague the debugger guy **** ENDING LOGGING AT Thu Jul 26 02:59:58 2012
