STM32F7 + QSPI Flash with FileX (Azure RTOS) – Need Sample/Reference

[Midhul_Pk]

Hello ST Community,

I’m currently working on integrating the MX25QL128 NOR Flash (connected over QSPI) with the STM32F746 microcontroller. My goal is to use it with Azure RTOS FileX and LevelX for filesystem access. I’m using STM32CubeIDE and the latest version of Azure RTOS.

Setup:

• MCU: STM32F746NG

• External Flash: MX25QL128 via QSPI

• Middleware: Azure RTOS (ThreadX, FileX, LevelX)

• Interface: QSPI in Memory-Mapped Mode

• Goal: Format, mount, and use FileX filesystem stored on MX25QL128

Request:

I’m looking for:

1. Sample code/project showing working integration of FileX + LevelX + MX25QL128 via QSPI on STM32

2. Any ST reference projects or application notes specific to this setup

3. Clarification on required QSPI mode/timing/memory map settings

4. Common pitfalls (e.g., erase before format, QSPI memory-mapped setup timing, etc.)

5. Any working FileX + LevelX configuration example (even with another STM32 MCU) that could help me align my integration.

Any working example or advice would be very helpful. Thanks in advance!

Best regards,
