Hi ， I am running into a problem 。 We are working on a project 。Using jetson NX module to detect button is pressed or not 。But there are only two GPIO （gpio421 and gpio422）can be used as expected， I can tell the difference between button is pressed or not with Pull-down resistor through their /sys/class/gpio/gpio421/value and /sys/class/gpio/gpio422/value。But other GPIOs like gpio268 、gpio424 and gpio 393 are set to pwm 。So , I am wondering if there is any way for me to change these pwm pins into pins like gpio421 or gpio 422。Because right now ，two GPIOs can’t satisfy our requirement，we have 7 buttons to press。
Thanks。
Hi, please refer to the Xavier NX pinmux sheet. You can choose the pin which “customer usage” can be set as “GPIO”.

ok，i will try it，thanks
