I have an rpmsg example[1] that runs on the BB Black. It creates
/dev/rpmsg_pru30 which allows the ARM to talk to PRU0.
I have a parallel example[2] that's supposed to run on PRU 1_1 on the AI and do the same thing. I thought it was working last year.
Now, it doesn't even create /dev/rpmsg_pru30.
Any ideas what might have broken since last year?
I'm running the current image (BeagleBoard.org Debian Buster IoT Image 2020-04-06) on the Black and the AI.
