Is my camera module working fine (all 3 LEDs light up)? What is camera continuous mode? Anyone have any information regarding this? I am working with the model zoo image classification project, and facing issue, after troubleshooting by blinking LED of the board. I found that the camera initialization is having error. Can anyone provide any information regarding this? Thanks

Hello @chew ,

I think you face the same issue as reported here.

The BSP_ERROW_UNKNOWN_COMPONENT can happen if the camera is not detected. It might be due either to a wrong connection or a malfunction of the camera board.

I advise you to plug and unplug the camera board while the board is not powered. A short-circuit can happen otherwise.

Could you please try with another B-CAMS-OMV camera board?

Thank you.

After checking the error code is BSP_ERROR_UNKNOWN_COMPONENT based on STM32H747I_discovery_errno.h
