Hello, i had the same problem with my disco board (f746g) yesterday. I don't know why, but in the debugger settings there was no external loader set anymore. After set it it worked fine.

Hi,

​

Was it the same scenario where you migrated a project from TouchGFX 4.16.1 to 4.17 ? What version of STM32CubeMX are you using ? Did you start a proejct from scratch or from the TBS for the STM32F746G-DISCO board available in TouchGFX Designer ?

Could you confirm that disabling the external flash loader causes your project to hard fault ? That seems strange :thinking_face:.

Hi MDani,

All of my problem after updating is solved when I decided to migrate from KEIL to STM32CubeIDE, It seems Keil has some bugs in this case

I suggest if you are using keil, probably your problem will solve after migrating to STM ide....

BR,
