Hi Everyone,
I have W25Q256JV and STM32L562CEU6 with 38 Pin Package and have OSPI (Single SPI, Dual SPI and Quad SPI option only). Below is my Clock Settings, OSPI (Quad SPI) with Quad Lines Settings and Error Status during Write Enable and main.c file.
Kindly check and let me what is wrong so it's going into Error Handler every time on Write Enable.
If any basic drivers are available for OSPI in Quad Mode for Read/Write/Erase.
Looking forward to your kind help...
static void WriteEnable(OSPI_HandleTypeDef *hospi) {
OSPI_RegularCmdTypeDef sCommand;
OSPI_AutoPollingTypeDef sConfig;
HAL_StatusTypeDef ret;
/* Enable write operations ------------------------------------------ */
sCommand.OperationType = HAL_OSPI_OPTYPE_COMMON_CFG;
sCommand.FlashId = HAL_OSPI_FLASH_ID_1;
sCommand.Instruction = 0x06; // Use standard Write Enable command for Quad mode
sCommand.InstructionMode = HAL_OSPI_INSTRUCTION_4_LINES; // Use 4-line instruction mode
sCommand.InstructionSize = HAL_OSPI_INSTRUCTION_8_BITS; // 8-bit instruction size
sCommand.InstructionDtrMode = HAL_OSPI_INSTRUCTION_DTR_DISABLE;
sCommand.AddressMode = HAL_OSPI_ADDRESS_NONE;
sCommand.AlternateBytesMode = HAL_OSPI_ALTERNATE_BYTES_NONE;
sCommand.DataMode = HAL_OSPI_DATA_NONE;
sCommand.DummyCycles = 0;
sCommand.DQSMode = HAL_OSPI_DQS_DISABLE;
sCommand.SIOOMode = HAL_OSPI_SIOO_INST_EVERY_CMD;
ret = HAL_OSPI_Command(hospi, &sCommand, HAL_OSPI_TIMEOUT_DEFAULT_VALUE);
if (ret != HAL_OK) {
// Log the error here
Error_Handler();
}
/* Configure automatic polling mode to wait for write enabling ---- */
sCommand.Instruction = 0x05; // Read the status register command for Quad mode
sCommand.Address = 0x0;
sCommand.AddressMode = HAL_OSPI_ADDRESS_4_LINES; // Use 4-line address mode
sCommand.AddressSize = HAL_OSPI_ADDRESS_24_BITS; // Standard 3-byte address size
sCommand.AddressDtrMode = HAL_OSPI_ADDRESS_DTR_DISABLE;
sCommand.DataMode = HAL_OSPI_DATA_4_LINES; // Use 4-line data mode
sCommand.DataDtrMode = HAL_OSPI_DATA_DTR_DISABLE;
sCommand.NbData = 1; // 1 byte to read from status register
sCommand.DummyCycles = 8;
ret = HAL_OSPI_Command(hospi, &sCommand, HAL_OSPI_TIMEOUT_DEFAULT_VALUE);
if (ret != HAL_OK) {
// Log the error here
Error_Handler();
}
ret = HAL_OSPI_AutoPolling(hospi, &sConfig, HAL_OSPI_TIMEOUT_DEFAULT_VALUE);
if (ret != HAL_OK) {
// Log the error here
Error_Handler(); /* every time goes into error handler here */
}
/* Polling finished successfully */
}
