Hello,

I try to access to the SD card with BSP drivers.

BSP_SD_Init and BSP_SD_ReadBlocks return SD_OK, but the read buffer

does not reflect

the values in SD (the buffer is

almost always

0).

Can you help me ?

Thanks.

The application FatFs_uSD works.

So it seems that BSP_SD_Init and BSP_SD_ReadBlocks from BSP examples are insufficient to read the SD.
