I want to use the HDMI outputs to drive external circuit. Required toggle rate is between 1MHz and 10MHz. Have BB black. uname -a Linux beaglebone 4.4.84-ti-r120 #1 SMP Sun Aug 27 03:11:07 UTC 2017 armv7l GNU/Linux cat /etc/debian_version 9.1 So I have to use the PRU unit. I was searching example to have a starting point. But it sucks already with the first step.
ll /sys/devices/bone_capemgr* ls: cannot access '/sys/devices/bone_capemgr*': No such file or directory I load the image from here: http://debian.beagleboard.org/images/bone-debian-9.1-iot-armhf-2017-08-31-4gb.img.xz What is my mistake? Device tree compiler is up to date device-tree-compiler is already the newest version (1.4.4-0rcnee3~stretch+ 20170719). 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. Found a lot of hints to use the 3.8 kernel. Think that one is already some years old, can't be true. Question: How to create the required device tree overlay, because /sys/ devices/bone_capemgr* is not existing?
