I have problems with receiving remoteproc messages on PRU1. The code works fine when configured and executed on PRU0, but PRU1 never receives any interrupts (event numbers set for each PRU accordingly).
I modified examples PRU_RPMsg_Echo_Interrupt0 and PRU_RPMsg_Echo_Interrupt1 to flip I/O pins with LEDs whenever interrupt comes.
On PRU0 example works as expected. Each time a message comes, the LED switches state. However, example for PRU1 behaves like it never receives any interrupts from ARM host. In my application I’m using interrupts to signal PRU1 from PRU0, and hey work fine.
Has anybody been able to resolve this issue?
I’m running kernel 4.14.94-ti-r93 on Debian Image 2019-01-27, with PRU tools installed by ti-pru-cgt-installer 2.1.5-0rcnee1~stretch+20180514
