QSPI Write Issue on STM32H745 with MT25QL512 in IAR

[Harsh_Gajjalwar]

Hello,

I am working on interfacing an external flash memory IC MT25QL512 with the STM32H745 microcontroller using QSPI in IAR Embedded Workbench.

The Problem:

When attempting to write data to the external flash using the HAL_QSPI_Transmit function, the operation fails at the following line:

status = QSPI_WaitFlagStateUntilTimeout(hqspi, QSPI_FLAG_TC, SET, tickstart, Timeout);

Details of My Setup:

• Microcontroller: STM32H745
• Flash Memory IC: MT25QL512
• Development Environment: IAR Embedded Workbench   

• Has anyone encountered a similar issue with the QSPI_FLAG_TC not being set during a write operation?
• Are there specific configuration or timing considerations for the STM32H745 and MT25QL512 combination that I might be overlooking?
• Any debugging tips or suggestions would be greatly appreciated.

Thank you for your support!!

Hard to say, you're pushing the content, so should have control of the speed of the transaction.

Are you placing a Debug View of the QSPI Peripheral Registers? Should probably avoid that due to secondary effects of the debugger, the status registers, and the data/FIFO registers.

Anything else trying to operate concurrently with the memory?

Able to get a logic analyzer on the pins?

Other code examples working? Clock/Peripheral enabled? ie non-zero content in registers and writable.
