Hi everyone, So I messed around with my beaglebone a little bit last night. I worked out the issues in my device tree source file so it is now compiled but I can't seem to get anything to echo properly to "slots" I compile my ".dtb" file but when I go to call the comman: echo PRU-GPIO-BLINK > /sys/devices/platform/bone_capemgr/slots I continually get the error: -bash: echo: write error: No such file or directory Is there are a different way to enable my device overlay or set the pins to the correct mode for the PRU? I have even tried copying, compiling and attempting to export the device tree overlay example from adafruit and still no luck.
The names of my files in /lib/firmware are as follows: PRU-GPIO-BLINK.dts PRU-GPIO-BLINK-00A0.dtb The part-number name in the .dts file is "PRU-GPIO-BLINK". Am I still missing something? I can post the updated ".dts" file if it would help. P.S. I have two questions since I am still relatively new at this: 1) What is a blacklist and why was it necessary to export to the .conf file to enable the remote_proc? 2) What is dmesg and where do I check them? Are you referring to "/var/log/syslog"?
