**** BEGIN LOGGING AT Thu Jan 26 03:00:02 2017 Jan 26 07:00:54 Hi all Jan 26 07:01:13 I have doubt regarding bbb pinmux for i2c Jan 26 07:01:25 can any one help? Jan 26 07:13:25 maybe ask your question and someone might know the answer Jan 26 07:19:52 what is the off set value for i2c1_sda and i2c1_scl? Jan 26 07:20:16 I want to enable i2c1 Jan 26 07:20:32 to do so, i need pinmux information Jan 26 07:20:47 so can anybody knows about it> Jan 26 07:21:08 have you read the BBB SRM? Jan 26 07:29:09 yeah I read Jan 26 07:29:23 if you see the am335x-bone-common.dtsi file Jan 26 07:30:39 for i2c2 they are using offset values as 0x978 and 0x97c Jan 26 07:31:34 but if you see in p9 connector the values are 0x150 and 0x154 Jan 26 07:31:41 I am bit confused here Jan 26 07:36:23 could it be because there are 2 mux values that can enable 12C1_{SCL/SDA} ? Jan 26 07:40:42 hi all! Jan 26 08:53:04 I am reading data from tsc adc fifo, but read data are odd. I checked the address of read data and they are ok. Moreover, I can read default values right. anyone had the same experience ? Jan 26 12:58:04 hey guys, i accidentally pluged 12V into BBB, now it only powers on if i attach it through USB, any idea? Is i broken or not? Also if i hook it on 5V again and when i measure voltage on the board it's around 1.7V Jan 26 12:58:36 hi Jan 26 12:59:35 lore4, hi Jan 26 13:00:22 hi nardev Jan 26 13:01:36 i hope somebody will help me soon :D Jan 26 13:09:15 nardev: According to the schematic the DC input goes to a TPS65217C that should support up to 20V input, but there's a few capacitors on the input side which is spec'ed at 10V - you might have blown the caps or even the TPS65217C Jan 26 13:11:23 ChanServ, :( Jan 26 13:11:30 so Jan 26 13:11:38 USB power is not related to that Jan 26 13:11:38 ? Jan 26 13:12:21 nardev: Check the schematic Jan 26 13:12:50 :( Jan 26 13:12:58 not capable to identify that :( Jan 26 13:13:08 winderind which capacitors i could check :( Jan 26 13:13:16 nardev: DC power goes to pin 10 and USB to pin 12 Jan 26 13:13:23 visually it's perfect, no traces Jan 26 13:13:33 aha.. Jan 26 13:13:37 so it's separated.. Jan 26 13:13:44 on the TPS65217C Jan 26 13:13:57 Try to locate C2 and see if it looks OK Jan 26 13:14:29 Personally I would solder a few wires to the USB connector and connect the power directly Jan 26 13:14:52 That's what I do with my Raspberry Pi's that lacks the seperate DC connector Jan 26 13:15:29 Chrille, .. will think about that... Jan 26 13:19:20 Chrille, C2 looks perfect Jan 26 13:20:02 Chrille, what is the C2 value so that i can test it Jan 26 13:22:38 nardev: https://www.google.dk/#q=beaglebone+black+schematic+pdf -> first hit - there's your schematic Jan 26 13:25:03 Chrille, sorry, ok thnx Jan 26 13:30:32 Chrille, i was never reading docs since faculty ... Jan 26 13:30:34 thnx Jan 26 13:31:00 btw afais it's C1 before the pin 10 on TPS... Jan 26 13:47:28 Chrille, the capacitor is ok... Jan 26 13:47:45 none is short circuited from both sides to gnd Jan 26 14:04:16 Chrille, just tested different PSU looks like powerjjeck is shit Jan 26 14:05:07 nardev: So it works if you connect 5V DC directly to the solderpads of the BBB? Jan 26 14:05:27 aha Jan 26 14:05:52 actually i tried some different psu Jan 26 14:07:59 Chrille, you just "pushed" me to think about docs.. i was behaving like dumb developer :) Jan 26 14:08:01 thnx Jan 26 14:39:58 hi there channel :-) Jan 26 15:01:16 zmatt: did you test channel id function in fifo data? Jan 26 15:11:42 I like this beaglebone black, but is there a similar board with onboard wifi and/or cell modem daughtercard capability? Don't need the hdmi or the USB powering. 5-30v power supplying would also be great. Jan 26 15:16:32 minnesotags, which one is yours rev. c or rev. a5c ? Jan 26 15:32:42 lore4: step id, yes it works Jan 26 15:41:56 zmatt: i can't read it correctly, it always return 0 Jan 26 15:45:25 zmatt: i've enabled ctrl reg bit 1-2, stepconfig1 one shot + averaging 4 + inp 5(AIN4) + inm 9 + refm 0 + refp 0, stepdelay1 0, ctrl 7 (enable sampling) Jan 26 15:46:24 fifocount goes to 1 and i read values(wrong) with the channel id 0 Jan 26 15:47:15 i checked structure addresses + PRCM register and they are fine Jan 26 15:48:28 btw, notice that I found PRCM register in TRM by myself... one step forward! Jan 26 16:18:59 https://hastebin.com/uzilaleqiz.cs Jan 26 16:19:56 i don't understand why the channel id still stays to 0 :( Jan 26 16:20:34 dury, the ones I have are PCB rev. B6 with 2gb Jan 26 16:39:39 see you tomorrow ;) Jan 26 22:20:48 hello, is there a tutorial on how to enable a boot logo on the display attached to the HDMI port of a beagleboard x15? Jan 26 22:29:28 hey there! what kind of throughput have people accomplished from either a kernel- or user-space USB function (beagle is data source, some USB host sink) Jan 27 00:07:15 Hi guys I need help on BBB. I am wondering how to change an LCD configured pin to a GPIO pin for example P8-46? How can I change it to mode 7? Jan 27 00:17:57 kk : key words: cape devicetree overlay pinmux Jan 27 01:04:11 CareBear\: we use mass storage gadget for imaging and flashing beaglebones Jan 27 01:04:48 never really benchmarked it though, but it seems decently fast Jan 27 01:05:25 raffo: you mean using plymouth or so ? **** ENDING LOGGING AT Fri Jan 27 03:00:01 2017
