Hi there, I'm trying to receive McASP0 interrupts (mcasp_x_intr_pend and mcasp_r_intr_pend) from the PRU of the BeagleBone Black. I have configured all system event channel mappings (system event 54 <-> channel 0 / system event 55 <-> channel 1) and host interrupt channel mappings (host N <-> channel N). Moreover I enabled the system events 54 and 55. The McASP is configured to trigger an interrupt at frame start for transmit and receive. If I trigger an event manually from the ARM (i.e. prussdrv_pru_send_event(54)), the event arrives as expected at the PRU. But if start a audio playback or capture via the McASP, nothing arrives at the PRU (I verified that the interrupts are definitely triggered from the McASP).
Do I need to configure the ARM interrupt controller, as well, so the system events are propagated to the PRUs? My PRU code is available on Pastebin <https://pastebin.com/Q9YVCM0b>.
