Hi Jerry:
Thank you for your answer.
I have another question is what the function of eeprom that on camera board? when I use the camera is must communicate with eeprom?

hello sunyanyan19860,

there’s plugin manager to detect camera ID during boot-up for camera sensor registration,
you may also check the developer guide, Device Registration for more details.
