Hello @ all, I am trying my first steps with the PRUss on the BBG, but nothing I read here, will work. Step by step: 1. I downloaded this image: bone-debian-8.6-lxqt-4gb-armhf-2016-11-06-4gb.img and installed it on sd-card 2. run update, upgrade and dist-upgrade. So my kernel is 4.4.30-ti-r64 3. cd /opt/source/dtb-4.4-ti && git-pull
Before, During and After this steps I tried to run the loader blink example: http://www.righto.com/2016/08/pru-tips-understanding-beaglebones.html For this I compiled the loader, the blinker and the devicetree. But the loader always reports prussdrv_open() failed capemanager tells me, that univ-emmc is loaded. I recompiled it, without acces to pru0,pru1,pruss,P8.11 and P8.16. I then compiled the devicetree of above example and after reboot I didn't had any problems loading it. Also I deactivated the universal cape in /boot/uEnv.txt to be sure univ-emmc doesn't make any problems. I also compiled the PRU-blinker-program of TIs Hands-on-Lab. Placed them on the board, linked them with /lib/firmware/am335x-pru0-fw and run modprobe pru_rproc / rmmod pru_rproc In lsmod, I can see, if I run modprobe the driver is loaded and after rmmod the driver isn't loaded. dmesg doesn't tell me anything. What am I doing wrong? Can somebody help? Would be a great thing, else I will give up on this device. It took me too long, until I found this forum -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
