Both these functions contain the code:"if((HAL_GetTick() - tickstart) >= SDMMC_DATATIMEOUT)"However SDMMC_DATATIMEOUT is defined as 0xFFFFFFFF so the timeout is very long (49 days with a 1ms tick) and therefore never occurs.That upshot is that if the...

Hi @Imen DAHMEN Unfortunatley I think you've misunderstood what I was reporting.This timeout value SDMMC_DATATIMEOUT is intended for use with the SDMMC peripheral register that specifies timeouts in SDMMC clock cycles - see the other uses in this SD...
