Hello;
I want to use 4Bit SDIO on STM32F407VGT6 MCU. I already set all parameters on lastest STM32CubeMx software.
RCC => External Xtall
SDIO =>4bit bus
My Ide is KEIL 4.73.
But this configuration is not working. When i use SDIO 1bit mode , it is works! 

I already tested my board and connections(pull-ups,caps...) with "https://github.com/MaJerle/stm32f429/tree/master/21-STM32F429_FATFS
4Bit SDIO Example. So my board is working 4bit SDIO mode with this example. I checked with oscilloscope. 

How can i run 4bit SDIO FATFS with STM32cubemx on STM32F4?
Bests,Thanks.
