I would like to notify my host program that PRU1 has reached the end of its execution.
On PRU1, I have:
MOV R31.b0, PRU1_ARM_INTERRUPT+16
where PRU1_ARM_INTERRUPT = 20.
On host side, I have (using python binding):
but it does not work; my host never comes out from pru_wait_event()…
I have to admit that I don’t understand yet very well how interrupts work!
