AGX Jetson Orin GPIO Pins + ZED X Driver

Hardware
1

I am using an Nvidia AGX Jetson Orin Dev Kit with the Zed X capture card installed. I am enabling certain IO pins from the 40-pin expansion header using the GUI provided by Nvidia and it creates a custom device tree overlay that gets loaded on boot.

This overwrites the ZED X Driver device tree changes that are made on installation. The same is true if the order is done in reverse, meaning ZED X driver installed first, reboot, and then update the GPIO pins.

This is preventing me from using both the capture card + GPIO pins in tandem and I am not sure how to proceed in order to have both working at the same time.

Hello,

Thank you for reaching out. Can you please send an email to support@stereolabs.com describing this issue ?

Thank you

why not use the csi? or the usb 3.0 ports?

I already have but it has been a few days since I have heard back.

I already bought the Zed X and capture card, I also get the high resolution with gmsl which is ideal for me.

In my experience, getting the 40pin header on the jetson to work reliably is a major PITA, and you will require some sort of downstream signal amplifier anyway due to the low current output. I would suggest using an external serial device such as an arduino handle GPIO.
