PROCESSOR-SDK-AM64X: GPIO INTERRUPT CONFIG FAIL IN AM64x

huang bin

Hi, I'm having some trouble configuring GPIO interrupts.When I configured the GPIO_39, I didn't know how the GPIO_INTR_NUM was determined.

I've tried testing from CSLR_R5FSS8 CORED_INTR_MAIN GPIOMUX_INTROUTERO OUTP_0 to CSLR_R5FSS8 CORED_INTR_MAIN GPIOMUX_INTROUTERO OUTP_15, but Sciclient_ rmIrgSet is returning an error.

How do I determine the rmIrgReq.src index and rmIrgReq.dst_host_irg?

SDK VERSION: mcu_plus_sdk_am64x_08_03_00_18

Hello bin，

I suggest you refer to the GPIO section of this document：AM64x Document

Regards，

Gary

AM64x Document does not specify the specific assignment, can you tell me how to configure it?

I ran the GPIO INTERRUPT demo, GPIO_43, also initialization failed, very troublesome.

I have consulted with a senior product line engineer for you, which will take some time
