A603 GPIO control?

[anteater]

Hello,

I saw a number of prior posts on individuals struggling to control GPIO pins on the A603 carrier board with the Jetson Orin NX and Jetpack 6.2.
Such as:

GPIO on A603 with Jetpack 6?

Hi, I’m using an Jetson Orin Nano on an A603 with JP6, and I’m getting nowhere with being able to access GPIOs. Evidently with JP6, Nvidia have deprecated the sysfs driver for GPIOs, requiring the use of libgpiod instead. But it seems that for the A603, the necessary device trees are missing entirely so that libgpiod has no idea how to control GPIO pins. I can manually modify the GPIO control registers using busybox, but it seems like libgpiod has no information on how to control actual GPIO s…

Is there now a recommended library or method to do so? Any guidance would be appreciated. All I would need is simple “turn on/off” control of certain pins.
