**** BEGIN LOGGING AT Sun Jun 24 02:59:58 2012 Jun 24 04:41:17 Im having issues connecting to BeagleBone on Mac OSX 10.6 - with screen /dev/tty.usbserial-TIVE2OAVB 115200 , I get !p in the terminal - anyone experienced this? Jun 24 05:09:23 Hi to all ! Jun 24 15:07:20 hm what was the file named to override the env settings in u-boot when booting from sd-card Jun 24 15:09:05 uenv.txt? Jun 24 15:10:59 thanks mru Jun 24 15:11:02 now I see it Jun 24 17:50:52 hi folks. after months of fighting angstrom's networking to try to get wifi working (with a variety of different adapters), I'm considering giving debian a try on my beaglebone. two questions: 1) can anyone confirm that PWM access works properly in debian squeeze? 2) are there any prebuilt images out there? I've found some instructions but they're a bit terse, and it's not completely clear what changes have to be made for beagleboard Jun 24 17:50:52 beaglebone Jun 24 18:04:59 Hello, I have this kernel and file system installed: http://blog.galemin.com/2012/03/buildroot-2012-02-for-beagleboard-xm-with-li-5m03-mt9p031-camera-support/ and have /dev/video0. But video for linux says VIDIOC_QUERYCAP says capture is not supported on video0 Jun 24 18:17:48 sbma44 what problems you have with wifi adapters? Jun 24 18:18:11 have to reboot Jun 24 18:21:48 woglinde: it's run the gamut. most recently I've been using the ladyada adapter and instructions but it won't associate with an AP. I did at one point have an adapter working (after disabling connman) but that was a kernel w/o PWM enabled, so I tried something more recent Jun 24 18:22:27 I see a newer angstrom image so I suppose I might as well try that once my ubuntu box finishes upgrading Jun 24 18:23:42 sbma44 hm use chipset name rather than product names Jun 24 18:25:26 hms looks like I crashed one of my sd-cards Jun 24 18:26:32 woglinde: I mean the tutorial here, which seems like a decent confirmation of a workable chipset: http://ladyada.net/products/beaglebone/wifi.html Jun 24 18:26:46 chipset is rtl8192 Jun 24 18:29:56 hm Jun 24 18:29:59 looks okay Jun 24 18:30:09 maybee conmann is not that smart Jun 24 18:30:23 I almost try to avoid nm and conman Jun 24 18:30:33 and rather use if/updown Jun 24 18:47:24 woglinde: I agree. it's very difficult for me to understand how connman is supposed to work; its interface is un-unixy, and it makes it impossible to take advantage of all the helpful message threads out there for other linux networking problems that use more common methods Jun 24 18:47:36 that's the appeal to moving to debian -- though I'd prefer not to have to build an image Jun 24 18:57:49 yavta seems to work, but I dont have /dev/media0 Jun 24 18:59:34 anyone knows how to fix the mac address of a beagle-xm on ArchLinux? Jun 24 19:02:06 The mac address is usually passed to the kernel as an bootarg from uboot Jun 24 19:06:10 HeadAche: do you know the argument name? Jun 24 19:15:20 ethaddr=00:11:22:33:44:55 Jun 24 19:15:50 actually that goes into the env parameter bootargs Jun 24 19:16:19 so do setenv bootargs ' ethaddr=' Jun 24 19:16:25 saveenv Jun 24 19:16:26 boot Jun 24 19:18:03 HeadAche: thanks, let me try that Jun 24 19:20:43 didn't work Jun 24 19:25:43 sbma44: config files as text is un-unixy? Jun 24 19:54:27 Hmm, seems the video0 node I've been playing with is an output video device :| Jun 24 20:23:35 koen: I'd say that the dbus interface is kind of un-unixy Jun 24 20:24:12 more to the point though, the project's documentation seems to leave a lot to be desired. at least that's the impression I came away with after fighting with it for a while. Jun 24 20:54:52 anyone done fast i/o with mmap? Jun 24 21:03:23 <_av500_> how fast? Jun 24 21:03:27 <_av500_> what interface? Jun 24 21:08:46 fast_mmap? Jun 24 21:11:50 welp, mmaping physical memory and accessing the gpio registers directly is faster than using /dev/blahblahblah, way faster Jun 24 21:12:03 I've only read about people doing it on the different beagle lists Jun 24 21:12:06 haven't tried it Jun 24 21:12:08 via /dev? Jun 24 21:12:12 thinking about writing a small library for it Jun 24 21:12:14 you mean via /sys Jun 24 21:12:22 sure Jun 24 21:21:36 Hi guys - any way of running Gnome with no display so that I can remote in with VNC? Jun 24 21:21:47 I've install gnome and x11vnc Jun 24 21:21:50 installed, even Jun 24 21:22:33 brillopad: x11vnc already requires a X server Jun 24 21:22:39 Actually, gnome was already installed Jun 24 21:22:39 use vncserver or some such Jun 24 21:28:16 Thanks Jun 24 21:28:35 Do formatted USB drivers automatically mount in Angstrom? Jun 24 21:31:04 brillopad no Jun 24 21:31:17 Thought not Jun 24 21:31:33 Just formatted a partition (/dev/sda2) and it shows up as type 'Linux' Jun 24 21:31:48 hm maybee systemd does it Jun 24 21:31:52 but I am not sure Jun 24 21:32:12 Every time I try to mount it 'mount -t ext3 /dev/sda2 /mnt/exthd' the board crashes and I have to power cycle Jun 24 21:32:34 on beagle? Jun 24 21:32:53 BeagleBone Jun 24 21:33:00 do you power it on via usb? Jun 24 21:33:03 or ac Jun 24 21:34:58 AC Jun 24 21:35:05 5V in. Jun 24 21:35:49 how much watt? Jun 24 21:36:05 Ah. Unsure. One sec. Jun 24 21:37:39 Watts not specified on the box - output current 3000mA (3A) if that's any help Jun 24 21:37:45 USB HD is powered separately, btw Jun 24 21:37:51 ups sorry Jun 24 21:37:55 yes I meant mA Jun 24 21:38:00 3 should be okay Jun 24 21:38:20 than its crappy usb driver again Jun 24 21:40:14 Crap. Any way of fixing? Jun 24 21:40:46 Why cant I use devmem to see this register?: ISP_CTRL RW 32 0x00000040 0x480BC040 Jun 24 21:41:00 what happens if you try? Jun 24 21:41:02 Unhandled fault: external abort on non-linefetch (0x1018) at 0x40047040 Jun 24 21:41:07 clock is off Jun 24 21:41:22 you need to turn on the isp interface clock first Jun 24 21:42:08 * HeadAche hunting for clock address Jun 24 21:42:39 *sigh* why the u-boot musb support dont works anymore Jun 24 21:42:54 you'd normally have the kernel manage the clocks Jun 24 21:43:12 but if you're feeling lucky, you can poke at the prcm registers directly Jun 24 21:43:56 brillopad no fix Jun 24 21:44:11 Balls. Thanks, woglinde. Jun 24 21:44:25 although if the kernel does decide to mess with the same register, e.g. to turn on or off some other clock, it'll overwrite whatever you did Jun 24 21:44:38 brillopad hm last question which kernel version Jun 24 21:44:52 brillopad maybee a newer kernel has some fixes Jun 24 21:45:00 How do I check kernel version? Jun 24 21:45:12 uname -a Jun 24 21:45:12 by looking at the version number Jun 24 21:45:15 uname -r Jun 24 21:45:23 -a prints so many numbers it can be confusing Jun 24 21:45:23 3.2.21 Jun 24 21:45:52 uhm where did you get it? Jun 24 21:46:47 meta-ti is still at 3.2.18 Jun 24 21:47:19 or are you using ubuntu? Jun 24 21:48:24 Can't remember Jun 24 21:48:29 I must be well out of date Jun 24 21:48:38 Which is the best image to use? Jun 24 21:48:38 o.O Jun 24 21:49:09 3.2.21 was released this week... Jun 24 21:49:46 Which of these should I use? Sorry, completely lost :-/ Jun 24 21:49:48 http://angstrom.s3.amazonaws.com/demo/beagleboard/index.html Jun 24 21:49:53 lol Jun 24 21:49:55 https://github.com/Angstrom-distribution/meta-ti/blob/master/recipes-kernel/linux/linux-ti33x-psp_3.2.bb Jun 24 21:49:59 the patch list Jun 24 21:50:59 I would use Angstrom-TI-GNOME-image-eglibc-ipk-v2012.01-core-beagleboard-2012.01.11.img.gz Jun 24 21:51:27 but they arent for bone Jun 24 21:52:33 kernel and uboot at least Jun 24 21:52:35 woglinde - downloading it now Jun 24 21:52:40 woglinde: stop confusing people, meta-ti is not on github Jun 24 21:53:05 denix args than settle it with koen not to confuse people Jun 24 21:54:01 ah okay Jun 24 21:54:06 sorry its in the reamde Jun 24 21:54:12 That's his mirror and WIP - he's free to do what he wants Jun 24 22:04:19 good nite Jun 24 22:25:40 Anyone else had problems with downloads using BeagleBone? Every time I try to download a 3mb file using wget or CURL, it gets 4%-9% in and then the download speed drops to 0. Using ethernet. Jun 24 22:43:25 Really starting to annoy me Jun 24 22:43:29 wget works 1 time in 10 Jun 24 22:43:34 No reason for it at all :-/ Jun 24 22:43:58 Every time I try, downloads 5% of the file and then stops Jun 24 22:44:24 8% that time. Jun 24 23:08:08 hi! I downloaded linux-validation kernel image, and copied the kernel config from /proc/config but ethernet is not working Jun 24 23:08:36 how to get it work? linux 2.6.32, as the original, beagleboard-xm, rev C Jun 24 23:14:52 Can I control a solenoid with a beaglebone? Jun 24 23:15:28 with the right drive circuits, sure Jun 24 23:16:07 So I can't just wire it directly to the BeagleBone? I need an additional part to go in-between? Jun 24 23:16:31 mru, I mean a small solenoid, for example 5V or 3V. Jun 24 23:16:35 murple: yes Jun 24 23:16:39 voltage is not the issue Jun 24 23:16:40 current is Jun 24 23:16:46 how much current do you need? Jun 24 23:17:46 and you might want to put some transient protection in there too Jun 24 23:17:58 I haven't got the vaguest idea how much current I need, I'm just trying to find out if it's feasible to control a small solenoid from a BeagleBone, preferably without any additional parts. Jun 24 23:17:58 That would have to be a tiny solenoid to drive it directly from an gpio pin Jun 24 23:18:05 otherwise the voltage spike when you shut off the current could fry the beagle Jun 24 23:18:11 hmm Jun 24 23:18:29 a gpio pin can source a few tens of mA Jun 24 23:18:38 How about this guy: http://www.sparkfun.com/products/11015 Jun 24 23:18:40 but they're not made for that Jun 24 23:19:15 you can probably get a ready-made driver for it somewhere Jun 24 23:19:23 they seem to make an IC for everything these dayss Jun 24 23:19:34 I see. Pun intended. Jun 24 23:19:38 hmm, the datasheet is in chinese Jun 24 23:20:01 Yes, and it also states that it's a pull whereas I need a push. Jun 24 23:20:29 Where would I start looking for an appropriate IC/driver for this type of thing? Jun 24 23:23:03 why the hell, even kernel 3.1 doesn't work with the eth. Is sees it, load the module, but link is not detected -_- Jun 24 23:23:23 original kernel image provided with the board works well Jun 24 23:24:44 mru, Well, thanks for your assitance. Jun 24 23:30:43 ifconfig -a sees no eth0? Jun 24 23:32:10 there is usb0 Jun 24 23:32:45 I enabled both smsc95xx and usb eth gadget, as Ive found on the internet Jun 24 23:35:54 I tried 2.6.32 from beagleboard git repo and vanilla 3.1 Jun 24 23:43:25 this is when you start fooling around instead of attach one GOOD ethernet chip -_- Jun 25 00:33:10 quiters Jun 25 01:23:12 Now I got /dev/media0 but my /dev/fb0 went away :( Jun 25 01:33:41 probe of omapfb failed with error -12 Jun 25 01:41:23 It works with dvimode=1024x768MR-16, but I need it to work in hdmi mode :| Jun 25 01:46:29 what do you mean by hdmi mode? Jun 25 02:13:46 i have it connected to a tv, need correct timings, I just got it working :D Jun 25 02:14:17 echo "74250,1280/110/220/40,720/5/20/5" > /sys/devices/platform/omapdss/display0/timings Jun 25 02:22:28 This link should work in about an hour: http://youtu.be/9SxRx_gZHuk **** ENDING LOGGING AT Mon Jun 25 02:59:58 2012
