Problem with integration of W25Q128JV on STM32U5A9

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!

Not clear what you see vs expect.

Certainly an excessive amount of whitespace, like you've not directly pasted from the original source

sCommand.OperationType = READ_STATUS_REG_CMD; // << NO !! THIS IS NOT THE COMMAND

Lot of code missing on nearly every subroutine using sCommand

sCommand.OperationType = HAL_OSPI_OPTYPE_COMMON_CFG;

sCommand.FlashId = HAL_OSPI_FLASH_ID_1;

sCommand.DQSMode = HAL_OSPI_DQS_DISABLE;
sCommand.SIOOMode = HAL_OSPI_SIOO_INST_EVERY_CMD;
...

Why on Earth are you driving the Chip Select manually? Chose the wrong pin in fabricated PCB?

Please enumerate the pins use in your implementation

Thank you for your response.
Yes, on the board I am using, the Chip Select is chosen incorrectly. Can this significantly affect the operation if I control it manually?
Pinout:
OCTOSPIM_P1_IO3 - PF6
OCTOSPIM_P1_IO2 - PF7
OCTOSPIM_P1_IO0 - PF8
OCTOSPIM_P1_IO1 - PF9
OCTOSPIM_P1_CLK - PF10
CS - PF11

Well it will preclude XIP / Memory Mapped mode operation.
