Don't close the thread quite yet please, in the other thread I was asking about sending and interrupt from R5 -> PRU. But now I'd like to do it the other way around, PRU -> R5.

Please refer to this on for a sample implementation: https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1261421/am2634-fail-to-generate-an-interrupt-from-pru-to-r5f

Let me know in case you face any issue. Its from AM263x but should work well for AM261x also.
