Not able to run the code into stm32h757i-eval board

Hello,

I'm working with stm32h757i-eval board.

I have generated a code using the example code for keypad from touchGFX.

During the debug the below is the message i received.

Debugger connection lost.

Shutting down...

But nothing is being displayed in the board.

I have attached the .ioc file for your reference

I have been working on this issue from a couple of days but there is no solution.

When you place breakpoint to main in both cortex for example to line gpio init , your code stop here or debuger lost connection soon?

As i write on other your Q better is start with example in TouchGFX without use IDE .

And too if you are beginner better is choice single core board.

Thank you for your response.

I started with the example code from the TouchGFX designer software and it has worked fine.

I want to customize my display configuration for which I have coded and has compiled successfully but I'm not able to display any content on the stm32h757i-eval board.

Sorry , but you need here write code and not what you do. We arnt Avengers...

Hi,

Were you able to write to your display before setting TouchGFX ?

If yes, can you check if the framebuffer is updated and sent to the display ?
