I would appreciate any help here!
I have been trying to get FATFS working on the STM32F4 micro controllers for quite a while now but have never been able to get it to work. I have stepped through the code and have had different errors though time however to latest one is saying the disk is not present or a hard fault when the drive is to be initialised. I'm using the STM32F429ZIT6 on a custom board debugging with the STM32F4 discovery board. I have also used this discovery board and a different SD card to test the software but it still doesn't work. I have read through the code example in the STMCube FATFS manual however that didn't work either - I had to change the example code just to get the volume mounted. I have the pins of the micro controller directly connected to the SD card without pull-ups/downs.
Any advice would be greatly appreciated!
