For now, we have only used ov5640 camera as it’s officially supported by our 820 uSoM. But we found another camera we would like to try out - Basler daA2500-60mc. They have their own library interface for the camera. We tried it plug&play, but the pylon library didn’t find the camera. We suspect that you have to do additional configurations to get it running, probably in the apq8096-db820.dtsi device tree. Are there any guides or pointers how to set up a MIPI-CSI camera?
AFAIK, the Basler userspace tool expects a different driver than the upstream camss for 820c. So you may want to contact Basler so that they point you to the right kernel tree.
