**** BEGIN LOGGING AT Sun Dec 20 02:59:59 2015 Dec 20 08:19:19 hey. is there a good adapter_khz setting to not get JTAG-DP sticky errors when using the onboard JTAG debugger for the original beaglebone? Dec 20 08:22:10 or in general, a way to not get the JTAG-DP sticky errors? Dec 20 08:25:51 * tbr never used the jtag on bbw, but have you tried with openocd? Dec 20 08:26:52 mcarberry: have you seen this? https://www.tincantools.com/wiki/Flyswatter2_BeagleBone_Black_How_To#JTAG-DP_STICKY_ERROR_on_startup Dec 20 08:27:42 tbr: oooh, that looks useful. i'll try that. Dec 20 08:27:47 thanks. Dec 20 08:28:23 http://elinux.org/OpenOCD_Troubleshooting:_JTAG_Sticky_Error Dec 20 08:28:38 which says pretty much the same Dec 20 08:28:53 also looks like the error is mostly harmless Dec 20 08:29:15 somehow i must not have been searching for the right thing. it seems to be preventing me from loading an executable over using gdb. Dec 20 08:29:25 although, maybe not if i do the reset stuff right Dec 20 08:30:46 or try updating openocd Dec 20 09:24:33 tbr, ended up getting it working! didn't really have to do with the stick errors, i had something else wrong. Dec 20 09:24:36 Thanks again! Dec 20 09:24:52 np Dec 20 09:24:57 glad you got it sorted Dec 20 10:05:16 mcarberry: it's a known problem in OpenOCD and being actively worked on Dec 20 10:06:53 tbr: the error is never "mostly harmless" since it means an access has just been discarded Dec 20 10:07:24 you can hope it was just something being polled that will get polled again, but I wouldn't call it harmless Dec 20 10:08:17 I was merely repeating what the wiki pages claim. feel free to edit them. Dec 20 10:10:21 that page sounds like a more specific issue and is pretty old Dec 20 13:18:05 veremit: yeah the omap3 has a DSP, a proper C64+ even (not that bastard child Tesla found on the omap4/5) Dec 20 13:27:36 veremit: and as GenTooMan mentioned it has some hw accelerators for video en-/decoding ... a loop filter module and a motion estimation module, and later also a module for quantization and variable-length coding Dec 20 13:27:47 and a sequencer module, probably an arm9 Dec 20 13:28:26 ("later" = in the omap36xx/dm37xx) Dec 20 13:40:53 especially the motion estimator sounds like something that might be of use to OpenCV Dec 20 17:59:02 zmatt .. interesting thanks for that Dec 20 18:11:20 hi there! hope to find someone to guide me into the right direction: Dec 20 18:11:54 i have : BB black, Chipsee 7" lcd capacitive. Dec 20 18:12:33 i need: hints to enable this with current debian Dec 20 18:12:38 debian@beaglebone:~$ cat /etc/dogtag BeagleBoard.org Debian Image 2015-11-08 Dec 20 18:13:31 Can anyone here help me out? Dec 20 18:18:23 Dec 20 18:19:25 well I'm sure someone can but you may have to wait a bit. also can you get the 7inch LCD to operate with the current installation. Do you need a new OS installation etc. Dec 20 18:22:24 is the chipsee one where they haven't done debian instructions .. its angstrom only? Dec 20 18:22:29 probably on an ancient kernel Dec 20 18:23:52 I liked angstrom but for some reason they've totally obfuscated how to package things with it the last 3 years. Dec 20 18:24:09 it's been sitting here for two years now, got a cd with angstrom and ye olde debian. both suck, since i can't get my favourite gps software to compile. Dec 20 18:24:10 exlfrnk: have a read through https://groups.google.com/forum/#!topic/beagleboard/Y-rcKPITy0Q .. but I think one of the guys you wanna talk to won't be here til tomorrow Dec 20 18:25:46 veremit: read that, but also read somewhere, that it's supposed to be in mainline debain nowadays. Dec 20 18:26:35 I guess, mohammad mostafa is the man? chipsee have a pretty much useless website whatsoever. Dec 20 18:26:37 exlfrnk .. fairly likely, you'll need to set the lcd resoltuion and timings in the kernel command-line Dec 20 18:27:25 oh boy, that sounds utterly frustrating. i hoped, i'd get things going a little smoother. Dec 20 18:29:10 yeah there's no auto-detection for anythiing besides the on-board HDMI framer Dec 20 18:29:18 veremit: at the moment, it's dark, nothing loads. i ssh in. somewhere i got that am335x-boneblack-bbb-exp-c.dtb shuld be the one overlay, but how do i load it? Dec 20 18:30:01 hm .. you need to compile it to a dtbo ? or .. yeah I not got the DT thing down yet :( Dec 20 18:30:31 veremit: i edit /etc/default/capemgr an put CAPE=BBB-EXP-C there, but that didn't help. Dec 20 18:30:45 nope that won't work Dec 20 18:31:13 you can put cape_mgr.enable_partno= .. or similar Dec 20 18:31:19 in uEnv.txt Dec 20 18:31:37 and you'll need a "video=XXXX" line (replacng the XX) Dec 20 18:32:50 veremit: http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Loading_custom_capes sais just the opposite! Dec 20 18:32:57 exlfrnk .. did you put that dtb into /boot/dtbs ? Dec 20 18:33:35 veremit: no, it's there already when you download the image. Dec 20 18:33:39 ah ok Dec 20 18:33:44 that's pretty damn recent :D Dec 20 18:34:03 so what does dmesg say? Dec 20 18:35:54 veremit: lots, but nothing useful. i fear i didn#t translate the filename correctly for putting it into the capemgr Dec 20 18:38:44 "translate" ? Dec 20 18:39:14 i found: Dec 20 18:39:17 bone_capemgr bone_capemgr: part_number 'BBB-EXP-C', version 'N/A' [ 17.239220] bone_capemgr bone_capemgr: slot #4: override [ 17.239238] bone_capemgr bone_capemgr: Using override eeprom data at slot 4 [ 17.239256] bone_capemgr bone_capemgr: slot #4: 'Override Board Name,00A0,Override Manuf,BBB-EXP-C' Dec 20 18:39:50 looks good so far .. Dec 20 18:41:25 anyhow, booting up from scratch, the whole display doesn't do a thing. not even falshing /no backlight. Dec 20 18:42:38 it's a bit weird. hold on a little, i'll try some hardware hacking. Dec 20 18:49:59 hmm .. you -should- see a backlight if it's got one Dec 20 18:50:10 otherwise that suggests a lack of power.... Dec 20 18:57:29 veremit: hmm. weird things happening. powered from lab power source, doesn#t take more than 0.46 Amp. no backlight, power in from the wirde green connector. tried power-reset (hold power button for long time til it reboots. Dec 20 18:57:45 no backlight. Dec 20 18:58:10 bbb boots, though. so power does get fed thru Dec 20 18:58:16 it may need 'turning on' somehow Dec 20 18:59:09 and that's probably associated with a lack of video signal .. but sometimes if you tilt the screen to the right angle, you can see something in the lcd, if the backlight is off Dec 20 18:59:36 I suspect, though, that you'll get Everything or nothing .. as you observe :/ Dec 20 19:00:54 veremit: aye, thnx, will check this. follow traces and see what's happening. thanky for your support. a little reassurenace goes a long way. Dec 20 19:01:38 veremit: life / wife calls. cheers & byebye Dec 20 19:02:24 kk pop back if you get it working .. and/or not :D **** ENDING LOGGING AT Mon Dec 21 02:59:58 2015
