I'm just trying to play around with PRU0. As very first I try to access PRU0 CTRL register - but it seems it is not accessible. I'm doing nothing more than writing a 0x00000001 into the register (reset PRU) and next wait until this bit goes back to 0 (signals completion of reset).
Unfortunately this never happens. And when I check out the register address in memory browser of CCS, There only ???????? is listed.
So it seems some required initialisation is missing. Does anybody have an idea what the reason could be for this?
Thanks!
