Question
nucleo-f767ZI QSPI direct read/write is not working
Hello @Amel NASRI ,
I am using nucleo-f767ZI board. I have custom LCD board which use NV3041A QSPI interface.
I am trying to read manufacture ID from NV3041A on QSPI interface.
My code is as below
static void MX_QUADSPI_Init(void)
{
/* USER CODE BEGIN QUADSPI_Init 0 */
/* USER CODE END QUADSPI_Init 0 */
/* USER CODE BEGIN QUADSPI_Init 1 */
/* USER CODE END QUADSPI_Init 1 */
/* QUADSPI parameter configuration*/
hqspi.Instance = QUADSPI;
hqspi.Init.ClockPrescaler = 4;
hqspi.Init.FifoThreshold = 1;
hqspi.Init.SampleShifting = QSPI_SAMPLE_SHIFTING_NONE;
hqspi.Init.FlashSize = 1;
hqspi.Init.ChipSelectHighTime = QSPI_CS_HIGH_TIME_1_CYCLE;
hqspi.Init.ClockMode = QSPI_CLOCK_MODE_0;
hqspi.Init.FlashID = QSPI_FLASH_ID_1;
hqspi.Init.DualFlash = QSPI_DUALFLASH_DISABLE;
if (HAL_QSPI_Init(&hqspi) != HAL_OK)
{
Error_Handler();
}
/* USER CODE BEGIN QUADSPI_Init 2 */
/* USER CODE END QUADSPI_Init 2 */
}
void NV3041A_ReadData(uint8_t command, uint32_t address, uint8_t *data, uint32_t len)
{
QSPI_CommandTypeDef sCommand;
HAL_StatusTypeDef status;
// Configure the command phase for reading
sCommand.InstructionMode = QSPI_INSTRUCTION_1_LINE;
sCommand.Instruction = command; // Your NV3041A read command
sCommand.AddressMode = QSPI_ADDRESS_1_LINE;
sCommand.AddressSize = QSPI_ADDRESS_24_BITS;
sCommand.Address = address;
sCommand.AlternateByteMode = QSPI_ALTERNATE_BYTES_NONE;
sCommand.DataMode = QSPI_DATA_1_LINE;
sCommand.DummyCycles = 0;
sCommand.NbData = len;

sCommand.SIOOMode = QSPI_SIOO_INST_EVERY_CMD;
status = HAL_QSPI_Command(&hqspi, &sCommand, HAL_QSPI_TIMEOUT_DEFAULT_VALUE);
if(status == HAL_OK)
{
status = HAL_QSPI_Receive(&hqspi, data, HAL_QSPI_TIMEOUT_DEFAULT_VALUE);
if(status != HAL_OK)
{
while(1);
}
}
}

/* USER CODE END 3 */
}
I probe logic analyzer of QSPI-data-0, data 1, clock and chip select line. I could not see any data being transmitted at end of "HAL_QSPI_Receive" API.
After debugging through register on my end I can see status register(QUADSPI_SR) is set to 0x01, which is being set by below code in HAL_QSPI_Receive API
/* Start the transfer by re-writing the address in AR register */
WRITE_REG(hqspi->Instance->AR, addr_reg);
When I change sCommand.AddressMode = QSPI_ADDRESS_NONE; I am able to see data without address (0xda) on QSPI line.
Can you please help me regarding this?
Let me know if any further information is required on my end.
