**** BEGIN LOGGING AT Sun May 29 02:59:58 2016 May 29 04:42:05 anyone here? May 29 05:10:27 pinctrl using devicetree overlay appears to be broken in the 4.4.9 kernel images May 29 05:10:33 can anyone confirm? May 29 07:24:08 If I use external 5V power the beaglebone black seems to shutdown when I connect the USB port to my computer. Is this expected? How could I workaround this? I'd like to connect the device to multiple computers without having so I need external power May 29 07:31:12 doesn't happen to me. do you maybe have significant potential differences between PC ground and the ground of your power supply? May 29 07:33:44 tbr: hmm, it's a laptop and I'm using a USB charger as a power supply so the ground should be pretty floating May 29 07:34:11 I could try using a USB battery instead May 29 07:34:12 try tying them together before you connect USB May 29 07:39:14 same seems to happen with USB battery pack May 29 07:40:18 tbr: I'm not exactly sure how I should tie the grounds to together in that case May 29 07:40:40 what sort of power supply are you using? May 29 07:40:40 tbr: I'd like the device to be mobile and something I can connect to multiple computers so I don't really know their ground level May 29 07:41:09 tbr: I've now tried a USB charger and USB battery pack May 29 07:41:27 connected to what? the barrel connector? May 29 07:41:33 yep May 29 07:41:45 it works fine as long as I don't connect the USB to a computer May 29 07:41:54 make sure that both can deliver upward of 1A May 29 07:42:08 The battery pack says 1.5A but the USB charger is only 1A May 29 07:42:10 is the board idle or is it doing something? May 29 07:42:20 idle, I gave it some time to boot up properly May 29 07:42:30 which OS are you running on it? May 29 07:43:30 tbr: I'm currently booting the USBProxy demo image from https://github.com/dominicgs/USBProxy/releases which I think is based on Debian 7 May 29 07:43:54 I can try with the "factory image" too if you think that could make a difference May 29 07:45:09 you should try with the default debian image to rule out some kernel problem May 29 07:45:14 sure May 29 07:45:27 booting off SD card is fine. hold down S2 while applying power May 29 07:45:54 I have the USBproxy image on SD card, the factory image is still on eMMC May 29 07:59:01 ok, then try that May 29 08:02:33 yep, working on that May 29 08:09:37 tbr: the issue seems to occur also with the factory image May 29 08:11:40 I guess one thing left to try is to use a 2A power supply May 29 08:31:57 lindi-: which version of the BBB are you using? May 29 12:22:32 lindi-: does it power off abruptly or is there some delay? May 29 12:23:56 I know the tps65217 power button driver had the stupid issue of interpreting any event from the PMIC (including connect/disconnect of a secondary power source) as if the power button were pressed, leading to shutdown when using a typical userland May 29 12:24:06 I don't know if it still has that problem May 29 16:14:16 hello May 29 19:41:33 So I've got a dumb question regarding the x15. Am I correct in believing that it won't have any analog I/O aside from the sound (enabled by McASP I guess)? Seeing that the Ti AM572x doesn't seem to have any piping for that http://www.ti.com/lit/an/sprabx8c/sprabx8c.pdf or am I missing something? May 29 19:43:00 you mean like ADC? May 29 19:44:26 And a DAC by all means, but mostly a 10 or 12 bit DAC, yeap May 29 19:44:31 ADC May 29 19:47:22 http://www.ti.com/lit/ug/spruhz6f/spruhz6f.pdf only mentions internal ADC for temperature monitoring May 29 19:48:01 given that the SoC has a ton of digital IO, it shouldn't be that hard to hook up ADC/DAC May 29 19:50:22 It isn't, but having it build in is a nice QoL factor. :) May 29 19:54:58 Hey guys, this channel may be too broad for my question but: Can anyone point me toward a Beaglebone cape that lets me hook up six external en/step/dir stepper drivers and run all six simultaneously? May 29 19:55:29 It's a choice, and tbh one I understand on multiple levels. One, with all of that high speed I/O noise is going to be a pain, and secondly non dedicated analog (for bridges to measure shockwave propagation at 1Ms/s+ with 16 bit ENOBS) is far more interesting in applications in the RPi/Arduino price bracket, where you can use it to look at the temperature in a turtle terrarium or whatever. May 29 19:57:03 NickParker: there are some capes for 3d-printing and such May 29 19:57:15 * tbr forgot the names May 29 19:57:36 tbr: Most I've seen top out at 5 stepper drivers, and even if they support more they may not support simultaneous motion on all of them at once. May 29 19:58:05 right, no idea then May 29 19:58:08 I shot elias at Replicape a message to see if that thing can be extended to do what I want May 29 20:01:20 Ooh he's quick, just got back and said it should work. Thanks guys May 29 20:32:53 g'morning May 29 20:32:58 * zmatt yawns May 30 02:29:10 'allo **** ENDING LOGGING AT Mon May 30 02:59:58 2016
