TouchGFX for STM32H750B DK Board

NKuma.20 · ‎2024-07-08

I'm trying to build up a GUI using TouchGFX for STM32H750B-DK board using the external memory but unable to get anything on screen. Can anybody share the any details or links for the same ?

I'm attaching the files for reference. If somebody can guide whats the error in it ?

below is the linker.id code:

Refer to the current attached files. When running the following files I'm getting just a black screen on the display.

What could be the issue in it ?

Below is the code for linked.id file:
