STM32F746IGT , 7 inch display With TouchGFX issues?

[GMano.1]

Hai

i have a STM32F746IGT Development board and (Waveshare) 7inch display(800x480).

Using tools are following bellow;

STM32CubeIDE 1.6.1

TouchGFX 4.16.0

STM32CubeMX 6.2.1

1. while run the code it's go to Hard Fault ();
2. after doing some change in LTDC start Frame Buffer address and some were it work fine. if there any changes in screen using TouchGFX tool display is also update.(Note: while display working time it's not enter the While() loop function)
3. Once switch OFF and ON the controller come back to fist position.

I change Stack Size is also it not work.

I don't have this board combo, get a Hard Fault Handler that outputs useful information so you can track down specifically what is faulting.

I dont check your code completely, but some tips:

1. i dont see any lines to config LCD no BSP or user code...
2. your set LTDC 0XD0000 but touch 0XC0000, pls set real functional ram area, without real ram = hard fault
3. timing for SDRAM vs LTDC vs MCU vs ... must be set correctly when not = hardfault , i recommend start tests with internal RAM usw.
4. use break points and locate code that runs ok and point for hardfault or as Tesla writes track faulting
