1.1.7.4.8 DRV_SDSPI_SyncWrite Function

bool DRV_SDSPI_SyncWrite(
    const DRV_HANDLE handle,
    void* sourceBuffer,
    uint32_t blockStart,
    uint32_t nBlock
)

Writes blocks of data starting at the specified address of the SD Card.

This function performs a blocking write operation to write blocks of data to the SD Card. The function returns true if the request was successfully executed. The function returns false under the following circumstances:

• if the driver handle is invalid

• if the source buffer pointer is NULL

• if the number of blocks to be written is either zero or more than the number of blocks actually available

• if the SD card is write-protected

• if there was an error during the SD card write operation

The DRV_SDSPI_Initialize routine must have been called for the specified SDSPI driver instance.

DRV_SDSPI_Open routine must have been called to obtain a valid opened device handle.

true - If the request was executed successfully.

false - If there was an error executing the request.

#define MY_BUFFER_SIZE 1024
uint8_t CACHE_ALIGN myBuffer[MY_BUFFER_SIZE];

// Address must be block aligned.
uint32_t blockStart = 0x00;
uint32_t nBlock = 2;

// mySDSPIHandle is the handle returned by the DRV_SDSPI_Open function.

if (DRV_SDSPI_SyncWrite(mySDSPIHandle, myBuffer, blockStart, nBlock) == true)
{
    // Write is successful
}
else
{
    // Error handling here
}

None.
