Hello!
I am using a Voxl2 that got shipped with version 0.9.5 of the SDK. I verified that my cameras (one M0061 imx412 and two M0072 ov7251 image sensors) are working before upgrading the SDK. Under version 0.9.5, running voxl-camera-server -l listed all my cameras, but after upgrading to 1.0.0 and running this command again, I am prompted with:
DEBUG: Attempting to open the hal module
DEBUG: SUCCESS: Camera module opened on attempt 0
DEBUG: ----------- Number of cameras: 0
DEBUG: Note: This list comes from the HAL module and may not be indicative
DEBUG: of configurations that have full pipelines
DEBUG: Number of cameras: 0
If I downgrade again, the cameras show up, so I'm sure that they didn't die. Even if I don't configure anything voxl-camera-server -l shows my connected cameras under 0.9.5, so I don't think camera configurations are at fault here, I have still tried to use the exact same configs and ran voxl-configure-sku and voxl-configure-mpa, but to no avail.
Following instructions to read from hi-res sensors I took a look at the dmesg output and found this:

I don't know why it seems to fail the important read..
