Debugging TouchGFX example project on STM32H757I-EVAL fails to program

Pieter25 · ‎2025-12-15

I have a new STM32H757I-EVAL board. The examples that can programmed on it ran perfectly.

I want to compile and debug the TouchGFX example myself but I only managed to kill the app that is running on it.

I've created the TouchGFX example from within STMCube32IDE by selecting the evaluation board, and then the example. It builds without errors.

In Debug Configuration, on Debug tab under External Loaders, I've added MT25TL01G_STM32H747I-DISCO.stldr with Enabled set to true and Initialised set to false.

When I select debug, it starts to program but fails after a while. Below is the output from Console.

What is wrong, and how can I fix it?

Hello @Pieter25 and welcome to the ST community,

Because you are using STM32H757I-EVAL board (Eval board) and you set the incorrect flash loader MT25TL01G_STM32H747I-DISCO.stldr (used for Disco board).

You need to use MT25TL01G_STM32H747-EVAL.stldr (I think it's compatible with STM32H757I-EVAL board with the same hardware configuration) :

Hope that helps.
