Touchgfx STM32MP135F-DK

AMend.7 · ‎2025-10-28

Hi,

I created a TouchGFX project for the STM32MP135F-DK board. When compiling the project, the error listed below appeared. Despite the error, I was able to load and debug the application on the board using the same procedure applied to any example running on DDR memory.
I verified that "the application binary file 'STM32MP135F-DK.stm32'" was not generated in the folder: Project Folder>\Binary\apps\STM32MP135F-DK.stm32 as per the link:

https://wiki.st.com/stm32mpu/wiki/How_to_install_X-TouchGFX_MPU_Addon

I am using a computer running Windows 11, is it necessary to install any additional software to generate this file?

Hello @AMend.7 ,

The scripts in the MPU Add-on require old python 2.7 to be used. Please make sure to have this version used to succeed running the post build steps (hitting 'Run on Target' button in the Designer).

Best Regards,

Akram
