Hi,
I can confirm that the new HQ cameras don’t (currently) work on the Jetson Nano. My guess is that the driver for the Sony IMX477 sensor is not implemented - at least, my Nano delivers me the message “camera not found”.
I am new with the Jetson, so there might be a solution around this issue, I found on the Wiki the link to RidgeRun, a company that might produce according V4L2 drivers, but the costs are enormous.
Maybe NVIDIA will jump in, since there will surely be a lot of people who want to use the improved camera module from the Raspberry Pi. And, if it’s not supported by the Jetson Nano, these people will go for another SBC solution, I guess.
BTW, AlliedVision has already drivers for their IMX477 cameras, but I don’t think that they might be of particular help for the Raspberry Pi HQ camera module.
