MCU-PLUS-SDK-AM243X: MULTI GPIOs interrupt initial failed

Tool/software:

Hi exports,

We need use two gpio(AA7/Y8) interrupts, but found not work.

Import project "gpio_input_interrupt" can reproduce the issue: Config as show in the below pictures, and running failed: Board_gpioInit()->Sciclient_gpioIrqSet()->Sciclient_rmIrqSet() (Line142) failed.

Modify gpios to C13/AA11 is OK, so why? I test some gpios, found that if the two GPIOs within the same bank will trigger the issue, otherwise ok.

Update:

When used two same bank gpios interrupt, I found only need enable one of the "Enable Interrupt Configuration".

The issue fixed, and I suggest that restrictions should be automatically imposed on sysconfig.

Hi Tushar,

How do you think about the above suggestion to impose automatic restriction in sysconfig when configure multiple interrupt pin in same bank, to avoid mistake. For example, when configured one pin, then gray the option under other pin.

Hi Liang, Tony,

Thanks for the above suggestion. I will discuss the above with Dev team to automatically force Sysconfig to disable option for interrupt enable for other pins if it is enabled by any one pin of the same GPIO bank.

Regards,

Tushar
