White screen with STM32F767 BITx microprocessor

[DCost.1]

Hi,

I am working with a customized board which has STM32F767 BITx microprocessor. I made a simple application with TouchGFX 4.13.0 integred with STM32CubeIDE 1.2.0.

The program builds and debugs correctly, but nothing appears on the screen, it is just white.

When I'm debugging it, it stops in the Infinte Loop of the startup_stm32f767bitx.s document and nothing happens.

/**
 * @brief This is the code that gets called when the processor receives an 
 * unexpected interrupt. This simply enters an infinite loop, preserving
 * the system state for examination by a debugger.
 * @param None 
 * @retval None 
*/
 .section .text.Default_Handler,"ax",%progbits
Default_Handler:
Infinite_Loop:
 b Infinite_Loop
 .size Default_Handler, .-Default_Handler

I don't know how to make it work and I would appreciate any help.

Thanks,

Dani
