Hi All :) Cannot get config-pin to work on HDMI Pins even though HDMI is disabled, any tips/know how would be appreciated. In /boot/uEnv.txt I have uncommented the ##BeagleBone Black: HDMI (Audio/Video) disabled: dtb=am335x-boneblack-emmc-overlay.dtb cmdline=coherent_pool=1M net.ifnames=0 quie

Hi All :) I have a program which ran with Beaglebone black, 3.8; I am updating the system to Beaglebone 4.4.27-ti-r63 and getting segmentation fault. Seems like the overlay is not loading, even when loaded manually. If you have a working configuration for Beaglebone 4.4.x and uio_pruss please

3.3v/1000ohm(1k) = 3.3mA 3.3/3000ohm(3k) = ~ 1mA I would put that one in, just in case, to make sure you dont fry the pin by accident if you have a dedicated part number for the servo, check you the datasheet for the control pin input impedance, its usually in the 10k and you don't need it; a w

look back there is a working program that I posted; blinks the user LEDS the way i have it working 1. cross compile the GCC(eclipse) program from windows -> bbb 2. PRU compile the asm on the BBB via terminal. Debug does work through eclipse. If anyone gets the PRU to cross compile would be great,

what page? usually you need to limit the current otherwise you may destroy the board, though 3mA is usually not enough to drive the servo On Tuesday, 1 September 2015 22:06:35 UTC+10, Frédéric wrote: > > Hi! > > In his great book 'Exploring BeagleBone', Derek Molloy uses a 1k resistor > between

For PRU recommend you have a look at https://github.com/abhishek-kakkar/BeagleLogic and also from memory there was a similar "CRO" application On Wednesday, 12 August 2015 19:54:02 UTC+10, TJF wrote: > > Hi! > > Host CPU and TSC_ADC_SS have different clock domains. Internal ADC clock > rate is

step 1. get the cross compile to work; I personally use http://gnutoolchains.com/beaglebone/ -> beaglebone-gcc4.7.3.exe Once you install it, open eclipse and try to compile the hello world program; once that works step

Hi, I have a basic application which use PRU1. program works 100% when executes as "root" from user space (via putty). I have a bash start up script, which synchronizes with RTC and executes my program. cat /usr/share/rtc_ds3231/clock_init.sh #!/bin/bash sleep 15 echo ds3231 0x68 > /sys/class/i
