Hi,
we have drive the st25dv64,it work fine,but when we use it transfer otafile to mcu use the st ftm protocol, it transefer ok in app,but we found that the FTM_FlushToFlash just call once in one segment(just write 512bytes in one segment transfer with 4951 bytes).
void FTM_FlushToFlash(uint8_t isLast)
{
uint8_t page_buffer[512];
uint32_t read_length = sizeof(page_buffer);
uint32_t write_length = read_length;
uint32_t flash_index;
if((current_command == FTM_FW_UPGRADE)
|| (current_command == FTM_SEND_PICTURE)
|| (current_command == FTM_SEND_DATA))
{
/* Get the offset of read data */
flash_index = ST25FTM_GetReadBufferOffset();
if(flash_index == 0)
{
/* If this is the first frame, removes command bytes */
uint8_t cmd;
ST25FTM_ReadBuffer(&cmd,1);
flash_index = ST25FTM_GetReadBufferOffset();
}
while(ST25FTM_ReadBuffer(page_buffer,read_length) == 0)
{
/* Flush as many data as possible */
APP_PRINTF("(ST25FTM_ReadBuffer(page_buffer,read_length) == 0)==\r\n");
Command_WriteBufferToFlash( 0, flash_index-1, page_buffer, write_length );
flash_index = ST25FTM_GetReadBufferOffset();
}
/* write the last incomplete page if the command ended */
if(isLast)
{
read_length = ST25FTM_GetAvailableDataLength();
write_length = read_length + ( (read_length % 8) ? 8 - (read_length % 8) : 0 );
memset(page_buffer, 0xFF, write_length);
ST25FTM_ReadBuffer(page_buffer,read_length);
Command_WriteBufferToFlash( 0, flash_index-1, page_buffer, write_length );
}
}
}
could you help on it.
the log is attached
