HAL SDIO Sector computation error

Hallo,

I noticed a BUG in

sd_diskio.c

in version 1.3.0 included in STM32CubeF4 v. 1.11.0 resulting in reading/writing from wrong sectors on big capacity SD cards. In functions

SD_read

and

SD_write

sector computation is casted to

uint64_t

too late resulting in clipping of most significant bits: Is:

if(BSP_SD_ReadBlocks((uint32_t*)buff,

                     (uint64_t)(sector * BLOCK_SIZE),                      BLOCK_SIZE, count) != MSD_OK) Fix:

if(BSP_SD_ReadBlocks((uint32_t*)buff,

                     (uint64_t) (sector) * BLOCK_SIZE,                      BLOCK_SIZE, count) != MSD_OK) Regards, Ra
