AM623: How do I set pins A18, B14 to a high level trigger interrupt mode in the device tree?

Hi Yuying,

What pinmux mode do you use on A18 and B14 pins?

Now you want to use these two pins to receive interrupt signals, so you want to change to interrupt mode

Your device tree sets A18 in mode 7 - GPIO mode. AM62x GPIO pins only support edge triggered interrupts, not level triggered interrupts.

You set B14 to mode 0 - SPI0_D1. I am not a SPI expert, but does SPI data lines directly trigger interrupts?

Okay, thank you. So mode 7 is interrupt mode, right, and what I want is an edge trigger

If you want to configure it to output mode, how do you set the high level edge trigger

OK,thanks
