I don't agree with this. Enabling the CAMSS node with just the TPG is of very low value to an end-user and doesn't "prove out" the CSIPHY, TPG and RDI path - which is the minimum entry point in upstream right now. I don't support less than a sensor at minimum. You guys must have a sensor you've used with this board ? --- bod
