Here is the code I am using:
Write: here as we discussed in Linkedin, SPI write works fine but Quad is not as the written data is corrupted somehow. Also, don't need to execute the Program execute cmd to store the data into Physical mem.
uint8_t W25qxx_PageProgram(uint8_t *pData, uint32_t WriteAddr, uint32_t Size)
{
uint8_t result;
W25qxx_WriteEnable();
result = QSPI_Send_CMD(&hqspi,W25X_PageProgram,WriteAddr,QSPI_ADDRESS_16_BITS,0,QSPI_INSTRUCTION_1_LINE,QSPI_ADDRESS_1_LINE,QSPI_DATA_1_LINE,Size);
//result = QSPI_Send_CMD(&hqspi,W25X_QUAD_INPUT_PAGE_PROG_CMD,WriteAddr,QSPI_ADDRESS_16_BITS,0,QSPI_INSTRUCTION_1_LINE,QSPI_ADDRESS_1_LINE,QSPI_DATA_4_LINES,Size);
if(result == w25qxx_OK)
result = HAL_QSPI_Transmit(&hqspi,pData,HAL_QPSI_TIMEOUT_DEFAULT_VALUE);
if(result == w25qxx_OK)
W25QXX_Wait_Busy();
//W25qxx_ProgramExecute(WriteAddr);
return result;
}
Erase: the bits are set to 0 instead of 1
uint8_t W25qxx_EraseBlock(uint16_t BlockAddress)
{
uint8_t result;
uint8_t page = 0;
uint8_t block = 0;
uint32_t addr = (block << 6) | page;
block_add[0] = (uint8_t) (addr >> 8);
block_add[1] = (uint8_t) addr ;
W25qxx_WriteEnable();
W25QXX_Wait_Busy();
result = QSPI_Send_CMD(&hqspi,W25X_BlockErase,BlockAddress,QSPI_ADDRESS_8_BITS,8,QSPI_INSTRUCTION_1_LINE,QSPI_ADDRESS_NONE,QSPI_DATA_1_LINE,2);
result = HAL_QSPI_Transmit(&hqspi,(uint8_t *)block_add,HAL_QPSI_TIMEOUT_DEFAULT_VALUE);
if(result == w25qxx_OK)
W25QXX_Wait_Busy();
return result;
}
I tried to follow instructions written by David Garcia, but didn't work.
