GPIO on Pixhawk Jetson Baseboard with Jetson Orin NX 16GB

Hi! I’m having issues with the Pixhawk Jetson Baseboard Bundle that has a Jetson Orin NX 16 GB on it. The problem is that I can’t configure or use the GPIO ports like I could on a Raspberry Pi, for example. I’m using the Jetson.GPIO library, which seems to work natively on Jetson devices. However, on the Pixhawk Jetson Baseboard Bundle, when I try to perform logical operations with one of the GPIO ports, the voltage doesn’t change.

To be more specific: when I send a logical 1 or 0 to the desired port, nothing happens — the voltage remains the same. I’ve already read many articles on the official Jetson and NVIDIA websites, but it seems that due to the custom build of the Pixhawk Jetson Baseboard, the GPIO configuration may be different.

I want to solve this problem as soon as possible. Thank you in advance!

So which board exactly is this? Can you share a link? And have you asked the manufacturer for support?

Ive been speaking with the manufacturer about this issue. They suggested me to put a resistor between the GPIO out and the Ground because of a “logical shifter” that might require a pull-down resistor with no load, which I havent tested yet.
