**** BEGIN LOGGING AT Fri Apr 21 03:00:03 2017 Apr 21 05:20:51 Hello Where can I find a list of connectors for Beaglebone Blue Apr 21 08:19:46 How do I get at the cycle counter in clpru? Apr 21 08:31:56 hello Apr 21 08:32:51 I can not configure the beaglebone so the 4 leds stay on Apr 21 08:36:07 hi? Apr 21 08:36:38 hello? Apr 21 08:36:53 hola Apr 21 09:11:18 \HELP Apr 21 13:13:49 what should one do with massive 'gbm_pvr_bo_import():327|ERROR> Import type <21761> not supported' with Qt on BBB? Apr 21 13:14:58 Please, I don't remember syntax to compile .dts file to a .dtb one to be used into /boot/dtbs/ Apr 21 13:15:17 is it right ?? : dtc -O dtb -o my_file.dtb -b 0 -@ my_file.dts Apr 21 13:46:40 I was on yesterday asking about a DTS for the beaglebone black wireless that allow use of the audio pin (e.g. P9_31) for the pru's can some point me in the direction of getting / building one? Apr 21 14:00:38 Hi, does anyone know how to exactly synchronize the current date and time to beagle bone? Any helps will be appreciated, thanks in advance! Apr 21 14:02:17 use NTP Apr 21 14:03:13 or gps Apr 21 14:03:25 or an i2c rtc .. Apr 21 14:04:30 I am so sorry since I am new to BBB, can I know how can I apply the ntp? Apr 21 14:04:43 thanks for the reply. Apr 21 14:06:11 Hey party people! Apr 21 14:07:14 Just plonked 'Jessie IoT (non-GUI) for BeagleBone' on a BBB. Cold boot time seems to be around 1min. Apr 21 14:07:23 Any suggestions on how to improve boot time? Apr 21 14:10:05 Ralph: systemd has the capability to produce boot analysis data Apr 21 14:10:55 Ralph: though if you want to have something really fast, you'll end up with a custom embedded linux build of Ångstöm or buildroot. Apr 21 14:15:12 I was looking at buildroot. Apr 21 14:16:32 All I'm after is RNDIS, PHP, SQLITE and Apache or Lighthttp Apr 21 15:19:10 does anyone know why a fresh am335x-bone.dtb copied from .../dtb-rebuilder/src/arm into /boot/dtbs doesn't work ??? (beaglebone white doesn't boot) Apr 21 15:20:01 its length is almost a half of a working original am335x-bone.dtb Apr 21 15:21:15 compiled a working am335x-bone.dts with dtb-rebuilder also produces a non-working dtb Apr 21 15:21:33 Hello, all. I have just heard about beaglebone blue... just what i need to stoop joining rapberry+arduino+other sensor... Apr 21 15:21:57 Can I buy one fron Spain, (in europ) ? Apr 21 15:40:16 I have a reproducible bug in the serial connection to all my beaglebone blacks where bytes go missing from the stream. I have written a minimal program that demonstrates the bug. Is this the right place for a bug report? Apr 21 15:41:27 I have upgraded to the latest image and drivers but the problem persists. Apr 21 15:42:23 david_h_: I think the mailing list would be a better place to report the bug. Apr 21 15:43:17 david_h_: https://groups.google.com/forum/#!forum/beagleboard Apr 21 15:45:27 Thankyou, I will post there instead Apr 21 16:19:04 boot time around 1 min? o.O Apr 21 16:19:12 * zmatt has ~ 10 seconds Apr 21 16:20:19 tbr: with debian that is Apr 21 16:20:39 As recommended I have posted my bug report to: https://groups.google.com/forum/#!category-topic/beagleboard/support/advanced/beaglebone-black/software/1n0IkcmhEq8 Apr 21 16:21:06 zmatt: suspected as much, maybe the person measured until something really late in the systemd thing happened? Apr 21 16:21:16 or booted from a super slow sd card :) Apr 21 16:22:00 well no I'm willing to believe the standard images are really full of crap, but a lean system can boot quite swiftly Apr 21 16:22:41 absolutely, with some work it shouldn't be hard to reach <3s, with a bit more maybe ~1s Apr 21 16:23:09 well it's already spending quite a bit of time in u-boot (even after killing the unnecessary 3-second delay) Apr 21 16:23:54 ah, haven't looked at u-boot output in a long while on mine Apr 21 19:26:30 hi guys how can i decrease my beaglebones boot time? for instance the wait for networking is a killer Apr 21 19:26:55 especially for someone waiting for a quadcopter to boot and then initialize Apr 21 19:39:51 why is it waiting for networking? Apr 21 19:40:17 useful to diagnose boot time: systemd-analyze plot >boot.svg Apr 21 19:42:47 zmatt, A start job is running for...work interfaces (47s / 5min 12s) Apr 21 19:43:37 i see this during boot, waiting for 5 mins is crazy for networking considering I wont be actively using network Apr 21 19:46:46 then disable it Apr 21 19:50:51 tbr, if i disabled networking, could i still use connman to handle wifi when i decide I want to plug a wifi dongle in? Apr 21 20:03:35 mistawright: you shouldn't need to disable networking, but normally startup shouldn't *wait* on it Apr 21 20:03:49 systemd is designed to allow stuff to run in parallel as much as possible Apr 21 20:08:48 zmatt, disabling networking seemed to still allow my ethernet to come up when connected but seemed to have sped up the boot slightly. Apr 21 20:09:33 if you'd literally disable networking, then ethernet wouldn't come up connected either Apr 21 20:11:55 if it's waiting 5 minutes on a start job that sounds like broken configuration Apr 21 20:16:30 zmatt, its using an older image that was recommended for arducopter using bbbmini. may see about writing the latest iot image there and checking. Apr 21 20:30:14 mistawright: here's an example boot plot of one of our beaglebones, running a fairly lean system with not much going on: https://liktaanjeneus.nl/boot.svg Apr 22 01:33:51 Hello... Apr 22 01:35:30 I am working with specific sensors on the BBB(W)(G)(L). Does anyone know where to look for what Linux calls a viable sensor? Apr 22 01:36:21 e.g. TMP36, some grove sensors, and/or XBEE? Apr 22 02:48:00 the TMP36 just outputs a voltage, so linux has no knowledge of these nor any need for knowledge of these, you just use an ADC input Apr 22 02:57:17 it seems to require a higher voltage supply than 1.8V, but using the 3.3V supply should be safe to use for this. it would be advisable to use a series resistor between the TMP36 and the adc input, and preferably connect the SHUTDOWN of the TMP36 to the RESET pin of the beaglebone **** ENDING LOGGING AT Sat Apr 22 03:00:02 2017
