Hi all,

Is someone else tried to implement solution about Fatfs (sd card) on discovery card with SPI communication ? I tried

I modified the SD SPI example (ST) for the F1 series to work with SDHC/HX cards, it was however pretty slow, and I've used SDIO on the F2/F4 parts.

Are you pin constrained to SPI? As I recall you can keep the SDIO in 1-bit mode on boards like the STM32F429I-DISCO which has a pin clash on the 4-bit implementation with the LCD Red signals.

Hi, Thierry.

Why not try

http://nemuisan.blog.bai.ne.jp/?eid=192848#STM32F4

? It contains recent fatfs0.10a(with SDIO/SPI HAL driver) and ton of tft-lcd drivers.
