Hello, I’ve a problem similar to this one. A support member from Nvidia asks me to create a new post. [image] GPIO02 can’t output high level Jetson Orin NX L4T : R35.3.1 GPIO02(Orin NX pin124,GPIO3_PP.06) can’t output high level.Normal input function. $ echo 446 > /sys/…

Yes, it can be removed if set io-high-voltage to disable. For the setting of enable io-high-voltage, the external pull-up is necessary.
