AM2634-Q1: AM2634 Sitara Hardware Interrupt

Part Number: AM2634-Q1

Hello TI Team,

I have the PROC111E2 with SDK 9.1.0.41 and CCS 12.7, I tried the gpio_input_interrupt example and it works fine.

Now I need the D14 as interrupt input, but somehow I can't trigger it. 

I simply changed the GPIO Pin in the syscfg and let the GPIO INT XBAR like it is. 

Do you have any ideas ?

    Hello Benjamin,

    The GPIO interrupts are spread across 16 GPIO wide banks, GPIO#_BANK0_INT to GPIO#_BANK8_INT. The # being the core you are using, so for the R5FSS0-0 core, you'd be on GPIO0_BANK0_INT to GPIO0_BANK8_INT.

    The example uses GPIO B8 which corresponds to GPIO23 on the device, so that is in BANK1 as that bank covers GPIO16-31.

    When you try and use D14, now you are using GPIO123. This is part of BANK7 which covers GPIO 112-127. So change your XBAR output to be GPIO_0_BANK_INTR_7 and it should work.

    Best Regards,
