Hullo guys , I 'm working with STM32F429I (on Open board from wave share) , and I m interfacing the OV2640 Camera , at the same time I have SD card attached , now the problem is that i can receive frames properly from the cam , but I can not seem to even initialize the card while using the cam , the DCMI and SDIO have shared pins , i disable the IOs from the DCMI after i get the frame , then i enable them for the SDIO .
When ever i remove the Camera , the card works perfectly . The clock supply to the DCMI is stopped after i receive the frame (so that it wont disturb the IOs of the SD)
but still , i can not seem to make them work on the same hardware Pins .
Any solutions ??????
