STM32429I-EVAL1 TouchGFX not drawing to the framebuffer

[Dennie de Groot]

I created a TouchGFX project for the STM32429I-EVAL1 board in CubeMX 5.0.1. I configured all the peripherals needed and verified that the LCD and SDRAM are working correctly. After generating the code in CubeMX I also generated the code in TouchGFX.

It seems however that TouchGFX does not draw to the framebuffer address (SDRAM). The values do not change and remain static. Am I missing something to make this work?

I included the .ioc file for creating the project.

Fixed it by enabling the LTDC interrupts.
