I'm working on a project where I use the STM32U5A9 microcontroller to control the W25Q128JV flash memory. I wrote a library to interact with this flash memory, but unfortunately I can't get it set up correctly.
The problem is that commands are sent incorrectly when this piece of code in the enableQuadMode function is executed:
CS_ENABLE();
OSPI_RegularCmdTypeDef sCommand = {0};
uint8_t reg;
HAL_StatusTypeDef res;
sCommand.OperationType = READ_STATUS_REG_CMD;
sCommand.FlashId = HAL_OSPI_FLASH_ID_1;
sCommand.DQSMode = HAL_OSPI_DQS_DISABLE;
sCommand.SIOOMode = HAL_OSPI_SIOO_INST_EVERY_CMD;
sCommand.InstructionMode = HAL_OSPI_INSTRUCTION_1_LINE;
sCommand.InstructionSize = HAL_OSPI_INSTRUCTION_8_BITS;
sCommand.InstructionDtrMode = HAL_OSPI_INSTRUCTION_DTR_DISABLE;
sCommand.Instruction = READ_STATUS_REG2_CMD;
sCommand.AddressMode = HAL_OSPI_ADDRESS_NONE;
sCommand.AlternateBytesMode = HAL_OSPI_ALTERNATE_BYTES_NONE;
sCommand.DataMode = HAL_OSPI_DATA_NONE;
sCommand.DataDtrMode = HAL_OSPI_DATA_DTR_DISABLE;
sCommand.DummyCycles = 0;
sCommand.NbData = 1;
res = HAL_OSPI_Command(&hospi1, &sCommand, HAL_OSPI_TIMEOUT_DEFAULT_VALUE);
if(res != HAL_OK) {
return res;
}
the logic analyzer displays this:
Maybe any of you have faced a similar problem or can suggest some steps to solve it? Any help or guidance would be greatly appreciated!
Thanks in advance!
