Hello ST Community,
I’m currently developing a project on the STM32U5G9J-DK2 board and working to implement a FileX + LevelX-based file system on the external NOR flash via XSPI.
I found the example project Fx_NoR_Write_Read_File in the STM32Cube firmware package, and while it’s functionally suitable, it does not include the .ioc file. This has made it challenging to fully understand and replicate the setup, especially regarding the XSPI (OctoSPI) peripheral configuration and the use of the lx_stm32_xspi_driver_glue.c for flash communication.
Why This Is Important:
What I’m Requesting:
Any help or direction from the ST team or community members would be highly appreciated, as it would unblock critical development efforts and ensure alignment with best practices.
Thank you very much for your time and support!
Warm regards,
Gowri M

Hello @Gowri_M
Thank you for your question about the .ioc file for the Fx_NoR_Write_Read_FileExample on the STM32U5G9J-DK2.
As noted in the Release Notes under Known Limitations, this application is currently provided without an .ioc file. This limitation will be fixed soon in the next release of STM32CubeU5.
Thank you for your understanding

Hello @MOBEJ
Thank you for the clarification and for pointing me to the release notes.
While I understand that the .ioc file is not yet available, I would really appreciate it if you could share some of the essential configuration details related to the FileX/LevelX setup used in the Fx_NoR_Write_Read_File example.
In particular, it would be very helpful to know:
Thank you again for your support!
Best regards,
