@Alex-Kushleyev Thank you for the information.

I tried to flash the VOXL2 to variant #0 but i doesn't seem to flash it following your instructions.

Is there a step I'm missing?

Thank you @Alex-Kushleyev, for the response. The current kernel variant is #1. I will flash variant #0 onto the voxl2. Does this kernel allow me to place a PMD sensor on J8 and J6, and have both be used simultaneously?

Also can I connect two M0172 adaptors with a micro-coax as a way to connect the PMD to the VOXL2?

I am trying to connect an IMX412 and an AR0144 to the VOXL2 with a M0084 cable on J7. Below is the custom configuration file I created. The issue I'm encountering is that neither sensor is being identified on J7U when I run 'voxl-camera-server -l'. Is there a hardware constraint regarding these cameras that I am not aware of?
