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 🤔.

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,

Yes Romain, i migrated a the project from 4.16.1 to 4.17 and i also updated the STM32CubeIDE from 1.6.0 to 1.7, after that the problem occured. It was a new project i created.

Ok, now I'm very confused, I really thought the problem came from disabling the external loader. Now i tried it again with the external flash disabled but I didn't get a hard fault. But I'm really sure that was the only thing i changed to get it to work.

Anyway, it works.

Hey Haji, no I do not use the Keil IDE, I'm already working with the CubeIDE, but thank you for the hint.

Check two extra things.

1- do you initiate your external flash before touchgfx init?

2- Make some delay with Hal_Delay function about 500 ms before peripherals initializing, It helps if some device need more time after resetting to be functional.

I hope it will help..
