Hi ! I am trying to make the same you was last year, writing in a SD Card with FatFS. I have spent three months with no success. Did you make it ?Could you help me anyway ? I changed the GPIO pins and the clock speed but I get no answer and the code stucks in the "Card Not Ready" part. I am using the same board that you, MSP430F5529 - LaunchPad.
Thank you very much !
