White screen on stm32f429i-disc1display

DLips.1
Associate II

Hi all,

I am trying to configure my stm32f429i-disc1 with the lates CubeMX 5.5 and TouchGfx 4.13. I have followed the instructions from here: https://touchgfx.zendesk.com/hc/en-us/articles/360010921760-TouchGFX-HAL-Development, but my display is still all white (there should be red background with simple 'hello world' string on it).

The project compiles and there is also 1s_cnt which increments properly. I've tried to debug the project and noticed that program enters inside functions:

  • void StartScreenPresenter::activate()
  • void StartScreenView::setupScreen()

on startup but only once.

Both the board and the cable are ok, because I can flash MCU with other project and then screen works fine.

Have you got any ideas what I am doing wrong?

I've adapted my code to yours and now it is working. There was SDRAM code initialization missing. Thanks you a lot! :)

Should the touch screen be working in this project since mine doesn't.
