AM335x GPIO1 interrupt in PRUSS

Keldy

hi,

i'm new in PRUSS module, how i map the GPIO1 rising edge interrupt to interrupt controller of PRUSS ?

Is there any magic number specific for GPIO1 interrupt that i need to write into PRUSS INTC (CMR[n]) register? so the PRUSS know the interrupt is come from GPIO1.

Thanks and Regards

Hi Keldy,

Only GPIO signals within bank 0 (GPIO0) are mapped to the AM335x PRU interrupt controller. GPIO1 is not mapped.

Documentation and example code are available on this link: https://github.com/beagleboard/am335x_pru_package. (See Ch. 6 and 7 am335xPruReference.pdf for additional details about how to configure the PRU interrupt controller and what interrupt events are available.)

Regards,

Melissa
