Hi there

I waste much time on mounting sdcard in my prgram. the chip is stm32F407vgt6 discovery and i work with Firmware version STM32Cube FW_F7 V1.9.0 , FATFS R0.12C and IAR IDE

in CubeMX, i choose SDIO in 1-bit mode with clock 84MHz(PLCK2) and FatFS --> SD Card. i leave Fatfs Options in Default(no change).

 

BSP_SD_WriteBlocks() and BSP_SD_ReadBlocks() work properly,

when i try to use f_mount function, i receive FR_DISK_ERR error as result Value.

my program is:
