**** BEGIN LOGGING AT Thu Mar 23 03:00:04 2017 Mar 23 04:55:39 SPAM Mar 23 10:33:34 bm Mar 23 10:38:52 mb Mar 23 11:56:31 zmatt: scanning through the e2e forums, it seems nobody ever solved that deepsleep resume puzzle Mar 23 12:09:35 is there any good simple script to create a bootable sd card image for BB Black? As far as I've researched, RAW mode is used now for MLO and U-boot, so there is need in only one partition, but everything I could find is seems to work old way Mar 23 12:50:12 thinkfat: which deepsleep resume puzzle? Mar 23 12:50:55 luneff: I think there's a script included? Mar 23 12:51:47 I'm not sure since I never use SD... if I had a desire for it then I'd just grab a copy of an eMMC image and flash that onto an SD card, and make any adjustments as necessary Mar 23 12:53:23 zmatt, included where? meta-bbb from jumpnow makes two partitions and I can't get it to boot properly. The one that does boot - Debian 8,6 - seems to have U-Boot etc. dd'ed into first sectors of image - and my BBB seems to work ok with it. But I can't seem to repeat it with a Yocto build :-( and I have to 3.3V FTDI to see what's going on Mar 23 12:54:38 *have no 3.3V Mar 23 12:54:51 luneff: oh, yocto Mar 23 12:55:28 I seem to have built everything required, just need to make it booting :-) Mar 23 12:55:47 you should really get a serial cable anyway, debugging boot issues blind sucks Mar 23 12:56:15 yes :-( Mar 23 12:56:57 for u-boot, the easiest solution is grabbing the first 1MB from a bootable image Mar 23 12:57:18 then recreate the partition table, create filesystem, and install onto that Mar 23 12:57:44 I thought about that. Yet, Debian positions dtbs differently than Yocto so Debian U-Boot might not find them properly Mar 23 12:57:47 though installing u-boot onto an existing system is also easy enough, as long as the first partition starts at offset 1MB or more (4MB is a good idea) Mar 23 12:58:01 then you'll need to build a suitable u-boot Mar 23 12:58:56 and dd it over some offset inside that 1mb? Mar 23 13:00:15 yes. 1. confirm the MLO has a configuration header: hexdump -C MLO | head -n2 | grep CHSETTINGS Mar 23 13:02:05 dd if=MLO of=$DEVICE seek=256 Mar 23 13:02:14 dd if=u-boot.img of=$DEVICE seek=768 Mar 23 13:02:37 et voila Mar 23 13:03:00 of course the old way of using a FAT boot partition should also still work Mar 23 13:08:57 isn't bs required here too? bs=512? Mar 23 13:16:02 no Mar 23 13:16:05 that's the default Mar 23 13:44:52 zmatt: the puzzle that after a deepsleep jtag doesn't work any more ... Mar 23 13:45:24 zmatt: or I'm having a problem nobody else has, which might hint that I'm still doing something very wrong Mar 23 13:54:22 zmatt, managed to get it working with yocto's wic. wic made a fat partition with u-boot and it works :-) Mar 23 14:02:23 zmatt: eh, no. actually, it's the same with debian Mar 23 14:07:17 thinkfat: so, if you reattach after it has left secure world, what sort of state is it in? what does the debug control register say exactly? Mar 23 14:08:05 zmatt: you mean 0x80001088, dscr? Mar 23 14:09:22 zmatt: 0x4b0f4011 Mar 23 14:10:35 zmatt: and 0x4b070012 after I release the DBGEN in the icepick core control Mar 23 14:14:06 hmm Mar 23 14:16:05 zmatt: guess you saw that: https://ghostbin.com/paste/ewcu9 Mar 23 14:16:58 zmatt: that's the icecrusher dump between a normal state and the "A8 stopped" state Mar 23 14:18:02 zmatt: only difference is bit 17 in the debug status register Mar 23 14:55:30 I want to get Qt5 running with omapdrm drivers from TI (BeagleBone Black). I can't start any OpenGL ES app because of "CRTC" errors (pvrsrv.. module is on, both "um" and "km" parts for meta-ti graphics is built and running). I learned that CRTC is related to DRM. How do I start an OpenGL ES app that needs DRM on BeagleBoard Black? Wayland? Weston? Just some environment magic? Maybe even X somehow? Mar 23 15:28:19 Hi I'm trying to get communication between an industrial photoelectric sensor O6H305 to be exact and my beaglebone green. I am using a PB24HQ I/O board to connect my 24v and industrial sensors. I don't know how to get my beaglebone communicating with this board, the board had a ribbon cable connection with 50 pins Mar 23 15:28:45 has* Mar 23 15:33:09 Last i was using the beaglebone black it was wotking fine. Today when powering up i am greeted to a black screen wjen Mar 23 15:46:02 luneff: I got Qt5 working with TI's new drivers, this was... interesting Mar 23 15:46:25 luneff: I've also communicated with robert nelson, I know he's working on supporting this in the standard debian images for beaglebone Mar 23 15:46:41 luneff: note that omapdrm is the wrong driver, am335x uses tilcdc Mar 23 15:47:48 luneff: I have no yet tried wayland, but both kmscube and Qt5's eglfs_kms work, so wayland should work as well Mar 23 15:47:52 *not yet Mar 23 15:48:06 zmatt, I've got denix talking in #yocto, he's TI employee responsible for all of it :-) The problems seem to be with libmesa/gbm stuff. And yes, I need to get Weston in the project Mar 23 15:54:25 heh, "responsible for all of it" - I'm pretty sure it will come to bite me... Mar 23 15:57:57 lol Mar 23 15:58:11 what's the scope of the word "it" in this context? Mar 23 15:58:36 denix, no offence :-D the whole thing looks much better than what Robert C Nelson does with beaglebone packages/scripts :-) Mar 23 16:00:31 I'm doing yocto for 3 days non-stop for the first time in my life :-D Mar 23 16:02:07 I mean he does great but I didn't manage to get SGX drivers working with Debian 8.6 :-( Mar 23 16:06:53 My beaglebone black was working fine two days ago. Today it will not boot. When connected to a monitor it displays a black screen, no terminal or mouse. Will not connect to my computer either, does not show up. I'm running ubuntu 16.04 Mar 23 16:07:19 luneff: he does great stuff in Debian! a lot of it gets borrowed from meta-ti though... Mar 23 16:08:31 Any suggestions on how to connect an industrial photoelectric sensor to beaglebone green? The sensor runs on 10-30 VDC Mar 23 16:08:45 denix, yes, I agree. Also, Yocto seems much more systematic and ordered Mar 23 16:08:50 Rcn does great stuff with arm kernels across the board .. Mar 23 16:09:07 he's one of the few kernel arm advocates in his role as apps engineer :) Mar 23 16:14:58 I need to bend his ear about applyig his patches to a ck- kernel Mar 23 16:15:10 mine variant of his patches on top won't compile :( Mar 23 16:15:15 he's been very helpful by email Mar 23 16:16:34 zyx_: what do the leds do? Mar 23 16:17:39 heh. no offence to anyone, I'm sorry for harsh words :-( Mar 23 16:18:04 but heh .. there's always exceptions :) Mar 23 16:18:19 poke him about it .. there's a good chance he'd want to find out why. Mar 23 16:18:28 Its a real pity he doesn't come in here so often .. eh zmatt ;P Mar 23 16:19:41 luneff: I PRd a minor tweak to his build script, concerning multiprocessing options, and he just merged it lol Mar 23 16:22:42 why wouldn't he? Mar 23 16:22:50 zmatt: the leds behave normally. When first turned on multiple flash, then settles into heartbeat pattern. Mar 23 16:23:03 zmatt: oh some of the devs I circulate with .. Mar 23 16:25:54 he's merged a fair number of patches from me too Mar 23 16:26:31 including recently the patches needed to get the new sgx kernel drivers working Mar 23 16:28:45 o,O Mar 23 16:34:26 Hey everybody! I have a very strange problem using a pressure sensor on the Beaglebone Black. It doesn't work and the I2C module frequently crashes when the sensor is hooked up unless... I attach a oscilloscope between SDA or SCL and GND. I also tried using a 10 MOhm resistor which is about the resistance of the oscilloscope but it only works with the latter. Mar 23 16:35:09 you shuold have pull-up resistors of around .. Kohm between Vcc and the SCL/SDA lines Mar 23 16:35:22 ie. both, separate resistors :) Mar 23 17:04:03 jkridner: why'd ya put the Blue wiki pages on Github? Mar 23 17:07:02 Tried that but it doesn't work either Mar 23 17:21:12 Okay, it works now... I'm using a 51 kOhm pull down resistor. Why would I need a pull down??? Mar 23 17:29:17 ehm, can you measure the voltage on the i2c of that module when it's not connected to the beaglebone? Mar 23 17:29:48 (just powered) Mar 23 17:30:27 Does anyone know how to invert the HDMI output on a BBB? Mar 23 17:30:34 invert? Mar 23 17:30:43 Yeah, upside down. Mar 23 17:30:54 Help Mar 23 17:30:58 there's not really any easy way to do that Mar 23 17:31:09 lcd panels do often have that ability Mar 23 17:31:14 Damn. My monitors are mounted upside-down. :) Mar 23 17:31:37 Hmm. You mean the built-in options in monitor? I will check it. Mar 23 17:31:38 ok so actually horizontally and vertically flipped even :) Mar 23 17:31:45 Ah, yes. Mar 23 17:32:40 I've tried "xrandr -o invert" and "xrand --output default --rotate inverted" without success. Not sure those options do what I am after anyway though. Mar 23 17:32:42 Hi all, is there any official solution available for externat RTC interface to BBB RevC? Mar 23 17:32:58 mrp_: xrandr won't work Mar 23 17:34:51 Ok. Mar 23 17:35:24 mrp_: lcd panel drivers can support flip horizontal/vertical fairly trivially, but monitors might not always bother exposing it as an accessible setting Mar 23 17:35:28 The GUI menus do not help either. The display settings allow me to choose "none", "right", "left" or "inverted" but have no effect at all when hitting apply. Mar 23 17:35:38 Alright. Mar 23 17:35:39 gui menus? Mar 23 17:35:57 I mean the options in the BBB GUI. Mar 23 17:36:15 oh, on the beaglebone? that's again just a frontend for xrandr, which won't work since there's simply no hardware support for it in the beaglebone Mar 23 17:36:24 Start->Settings->"lxqt settings"->"Monitor settings" Mar 23 17:36:29 Aha. Mar 23 17:36:57 What a bummer. :( Mar 23 17:37:31 Guess I'll have to use a NUC or dismount and remount the monitors. :) Mar 23 17:37:57 in cases where the gpu is used it can be used to rotate (albeit at some expense in performance), but it's not being used by X11 Mar 23 17:44:08 Ok, thanks zmatt for the help. :) Mar 24 02:01:19 hi, I just got a Beaglebone green wifi. When I connected it to home network using wpa2 connection. It works great. But my school using enterprise wifi connection which provide by user name and password. Any of you happen to know the solution for this please? Mar 24 02:06:00 hi, I just got a Beaglebone green wifi. When I connected it to home network using wpa2 connection. It works great. But my school using enterprise wifi connection which provide by user name and password. Any of you happen to know the solution for this please? Mar 24 02:06:58 what wifi utility/config-app are you using? Mar 24 02:07:22 it should work fine with wpa_supplicant/network-manager/connman ( Ithink) Mar 24 02:13:19 hi ver| laptop, I don't know much about this wifi thing **** ENDING LOGGING AT Fri Mar 24 03:00:00 2017
