This a continuation of the original issue, 1185701.
Summary: using mcu_plus_sdk_am64x_08_03_00_18, modify examples/drivers/gpio/gpio_input_interrupt/ to use MCU_GPIO0_21 pin as interrupt source. I'm using this version of SDK because later versions don't have board.c. I need board.c in order to setup to use MCU GPIO interrupt router, and I don't see how to do this using sysconfg.
I modified TISCI SYSFW to allow routing of MCU_GPIO0_x interrupts to R5FSS_0_0 core. These interrupts would otherwise be routed to the M4 core.
I see in board.c:Sciclient_rmIrqSet() that the interrupt route setup is sucessful. I see that MCU_GPIO0_21 is toggling and I can correctly read the state of the pin. Interrupts should be happening, but they don't.
Can you provide a working example of interrupt code for R5 from MCU_GPIO0_x? Can you check over the attached files?
