I am using STM32CUBEMX to generate code for the STM32F769I-DISCO dev board. I configured it so 4-bit data transfer mode is enabled, however, SD_WideBus_Enable() fails because SD_FindSCR() returns an SCR that is all zero. I simply commented out the SCR wide bus check and everything works fine i.e. I am able to use 4-bit data transfer mode:
Just thought I'd let ya'll know.
