Using FileX with MT25QL128 QSPI Flash on STM32F7

[Midhul_Pk]

I'm currently working on a project using the STM32F746NG microcontroller, and I need help getting Azure RTOS FileX running on an external MT25QL128 NOR flash connected over QSPI.

I'm using:

• STM32CubeIDE

• Azure RTOS (ThreadX, FileX, LevelX)

• MT25QL128 connected via QSPI in memory-mapped mode

The goal is to format the QSPI flash, mount it using FileX + LevelX, and perform basic file operations like read/write.

Has anyone implemented this successfully, or is there a working reference/example available? Even if it's for a different STM32 MCU, that would be really helpful. Specifically, I'm looking for:

• A working sample or example project

• Any application notes or documentation from ST

• Correct QSPI configuration (mode, memory mapping, etc.)

• Common pitfalls or tips for LevelX integration

I’d appreciate any suggestions or shared experiences!

Thanks in advance,
Midhul

Done with FATFS

Used 4K sectors based on minimum erase size. Used command mode to permit read/write operation.
