**** BEGIN LOGGING AT Wed Aug 31 02:59:58 2016 Aug 31 03:00:33 I have a BBB. I am trying to use GPIO66 as an input but the value is always Zero (0). I have done the following: 1. Used DD-GPS-00A0.dts as the overlay compiled and booted correctly. 2. echo 66 > /sys/class/gpio/export; echo in > /sys/class/gpio/gpio66/direction ; echo rising > /sys/class/gpio/gpio66/edge . From there I have jumped/shorted P8.7 and P9.3 which should drive a Value of 1 but /sys/class/goio/gpio66/value is 0. Aug 31 03:01:30 I repeated this without the overlay on GPIO49 (i.e. just the Sysfs) but this did not work. Aug 31 05:48:39 help me Aug 31 05:49:51 my Beagleboard Xm rev C2, not image generates Aug 31 05:50:28 enter through of SSH Aug 31 05:50:57 to nano /boot/uEnv.txt Aug 31 08:48:32 Hi, can I use the bbb timers with the PRU Aug 31 09:44:17 hii Aug 31 09:46:04 i need help Aug 31 13:36:02 hellow Aug 31 13:36:06 hello Aug 31 13:41:03 Hi, I am still seeking an answer: Aug 31 13:42:16 I have the beaglebone green, which has the groove four pin connector. I want to change the voltage on pin3 to +5V. where can I connect a thin wirewarp to get this +5v in the board? Aug 31 13:42:25 I use P9_7 as a default Aug 31 13:42:56 obviusly I soldered the pin off the pcb, and solder it to the wire. Aug 31 14:31:35 Hi Aug 31 14:32:43 am trying to boot the beaglebone black with u-boot images in sd card. My interest is to get the u-boot# command and then run the u boot commands Aug 31 14:34:12 when i am pressing the boot button and powering up the board, nothing happens.. Aug 31 14:46:01 krishna: do you have a serial debug cable attached? I think you're highly unlikely to see it on the hdmi interface .. what are the LEDs doing when you perform those operations? Aug 31 14:47:39 hi...veremit...i do not have..a debug cable...attached... Aug 31 14:48:21 as far as I know .. because the hdmi isn't configured when uboot boots .. the only place you will see it is on the serial console Aug 31 14:49:26 when you say serial console...u mean to say..the 3.3v USB to SERIAL UART TTL..right ? Aug 31 14:49:53 I'm not 100% sure whether the heartbeat LED even starts at that stage .. but you'll get a steady power LED ... Aug 31 14:50:08 yes .. the J! header Aug 31 14:50:10 J1* Aug 31 14:50:19 yes..i see only see the power led Aug 31 14:51:30 ok .. so once you've got a serial cable on the J1 pins (1, 4 and 5 iirc) connect to the board at 115200 board, no flow control, 8n1 .. and you'll see the uboot prompt there :) Aug 31 14:51:59 possibly pins 1,5,6 .. mine isn't here .. *wonders where it IS* Aug 31 14:52:24 (I know its got purple and yellow wires) Aug 31 14:52:43 yup..i will find out from the datasheet...the FDTI cable..right... Aug 31 14:52:45 ah I can make another :D Aug 31 14:52:51 yes, ftdi is most popular Aug 31 14:53:20 one more question...a basic..one...but this is bothering me... Aug 31 14:53:32 the reason the display isn't initialised at first start .. is the pins may be used for other purposes, so driving them is a bad idea :D Aug 31 14:54:41 okay, I will try with J1 header and...get back **** ENDING LOGGING AT Thu Sep 01 02:59:58 2016
