I am using the stm32f746-discovery board with the ov9655. I downloaded a program from the internet and programed the MCU using st-link utility(Interfacing camera to the STM32F7 Discovery – Embedded Intelligence ). However, every time I connect the camera, the (1) MCU enters in a reset state, (2) the LCD stays blank, and (3) the ethernet GREEN LED starts blinking. What is happening with my board? What the ethernet green light means?
