Why working the simulation not work on the target?

I have an STM32469I-DISCO kit. I followed tutorial 2 in Touch GFX and tested it with the simulator and it worked fine. Then I tried to run it on the target board. The program downloaded but the screen remained blank yet Touch GFX said it was successfully downloaded and verified. I tried using STM Cube IDE and the same thing happened. Then I tried STM Cube programmer with the same result.

Hi,

The simulator does not reflect the performances on target. There can be many reasons why your project does not work on the board, like a wrongly configured display or memory. Did you start your project from TouchGFX Designer with the TouchGFX Board Setup for the STM32F469 disco board ? There are 2 different projects depending on your board revision (check the tag on your board) so I think your issue might come from selecting the wrong TouchGFX Board Setup in TouchGFX Designer.
