Hello TI

The version of SDK I use:ti-processor-sdk-linux-rt-am62xx-evm-09.02.01.09

The problem is described as follows: I exported GPIO1_31 by means of export in the application layer and found that the level of this pin could not be raised. May I ask what is the reason?

I also configured the device tree accordingly.

Hello,

GPIO1_31 is the same pad as EXTINTn which is connected to the reset module of the SoC. Are you using EXTINTn in your design?

See the Data Sheet for AM625: https://www.ti.com/lit/ds/symlink/am625.pdf

Is GPIO0_42 working as expected?

Also, you can try moving the pinctrl parameters to a separate reference node, but I don't think it would change anything.

Best Regards,

Anshu
