Touchgfx + STM32H735G-DK Eval Kit

[kgb]

Hello everyone,

I am currently trying to integrate TouchGFX into an existing STM32 project (an FDCAN master node application), and I am facing several issues.

I enabled the TouchGFX generator in STM32CubeMX and configured all required peripherals (LTDC, FreeRTOS, DMA2D, OSPI/HyperRAM, clocks, etc.).
I also adjusted the clock configuration to match the display timing.

However, after flashing the application, the screen remains completely black.
Nothing I have tried so far has made any difference.

I have now discovered that the thread I created for the TouchGFX task is never executed, and I have not been able to find the root cause of this.

Any hints or guidance would be greatly appreciated.

  osKernelStart();

  while (1)

	  printf(" if while  bad news \r\n");

}

 TouchGFX_Task in app_touchgfx.c :  i am  not getting this print message :(

void TouchGFX_Task(void* argument)
{
    // Calling forward to touchgfx_taskEntry in C++ domain
    touchgfx_taskEntry();
    printf("touchgfx task\n\r");
}
