Beaglebone black PRU - counting pin state changes

[donaldshimoda]

Hi,
Im trying to get my BB PRU counting ping state changes on four inputs P8-11 P8-12 P8-15 and P8-16 and share in memory to be read for external code (running in main arm cpu of BB black).
I read every info on the web, cooking pru book, exploring bb book, etc, no luck at all. Im lost i have background on assembler on microchips pics but cant get this working, even the samples for output led dont work.

AFAIK i must produce a remoteproc firmware , load onto PRU, and go on. Again, the easiest sample for led blinking dont works and i lost two weeks on this.
Theres anyone here helping me with this task? I can pay for the job.
Please contact me. I have the hardware ready on my desk.

best regards.
