I am working with the STM32439I-EVAL2 board and my OV2640 camera is not functioning properly. I have been testing it with the MB1063 Demonstration example from the STM32CubeF4 software and when I try to use the camera it shows: "Error while Initializing Camera Interface. Please, chech if the camera module is mounted" on the LCD daughter board, even though the camera module is mounted and connected to the board. Has anyone else had this problem and solved it? It is possible that I need to tri-state SAI1-SDA, but I am not sure how to do this. Any help would be much appreciated.
