Posted on July 18, 2017 at 17:04Hi I have built the project STM32Cube_FW_F1_V1.6.0\Projects\STM3210C_EVAL\Applications\FatFs\FatFs_uSD, but he was off with a bug in FatFs study showed that when the functions
BSP_SD_WriteBlocks uint8_t(uint32_t *pData, uint32_t WriteAddr, uint32_t NumOfBlocks, uint32_t Timeout)
BSP_SD_ReadBlocks(uint32_t *pData, uint32_t ReadAddr, uint32_t NumOfBlocks, uint32_t Timeout)
STM32Cube_FW_F1_V1.6.0\Drivers\BSP\STM3210C_EVAL\stm3210c_eval_sd.c
there were bugs I've attached the corrected file
I found 1 error when read sector function
static void SPIx_ReadData(const uint8_t *Data, uint16_t DataLength)
error reading 8 bytes, that it was not necessary to fill the buffer with 0xFF
in
stm3210c_eval.c
/**
* @brief SPI Read Data from device
* @param Data: value to be read
* @param DataLength: length of data
*/
static void SPIx_ReadData(const uint8_t *Data, uint16_t DataLength)
{
HAL_StatusTypeDef status = HAL_OK;
uint8_t *pData = (uint8_t*)Data;
memset(pData, 0xFF, DataLength);//todo ????????? ??? ??? ??????? ?????? ?????? ? ???????
// ?????? 8 ???? ???????? ????????
status = HAL_SPI_Receive(&heval_Spi, (uint8_t*) Data, DataLength, SpixTimeout);
if(status != HAL_OK)
{
/* Execute user timeout callback */
SPIx_Error();
}
}
