Black Screen on STM32F469I-DISCO with TouchGFX and DAC1 and DAC2 Enabled.

[Kneepatch]

My STM32F469I-DISCO does not fully initialize when I enable DAC1 and DAC2 on a new TouchGFX 4.20.0 project.

If I don't use TouchGFX, but just the latest version of STMCubeIDE (1.1) then everything works fine. What am I missing here? I've been able to use the DACs and TouchGFX on this development board in the past.

Debug or compare generated code and locate diff or ... and latest IDE you mean 1.10.1

Yes, latest IDE being 1.10.1.

Turns out that I didn't have enough heap and stack memory. Increased both and now I get DAC and the touchscreen. Thanks for your help!
