Posted on September 18, 2015 at 19:36Hi,
There is a bug in function SD_CmdResp1Error. Whe using FatFS with SDIO, when mount fails but the f_open is called, the system hangs in following function:
static HAL_SD_ErrorTypedef SD_CmdResp1Error(SD_HandleTypeDef *hsd, uint8_t SD_CMD)
{
HAL_SD_ErrorTypedef errorstate = SD_OK;
uint32_t response_r1;
while(!__HAL_SD_SDIO_GET_FLAG(hsd, SDIO_FLAG_CCRCFAIL | SDIO_FLAG_CMDREND | SDIO_FLAG_CTIMEOUT))
{
}
if(__HAL_SD_SDIO_GET_FLAG(hsd, SDIO_FLAG_CTIMEOUT))
.......................
The system hangs in while loop and come never out of it (only after reset). I dont know the exact reason but this HAL-Code seems to be forgotten to write.
Osto
