I'm fighting against installing klipper on a CRAMPS + Beaglebone black
After a tons of problem with the libraries, now it is able to create the firmware for PRU unit. Unfortunatly now I have this problem:
mcu 'mcu': Unable to open port: [Errno 2] No such file or directory: '/dev/rpmsg_pru30'
How can I create it?
Thanks
