Hi,

Are you working with a custom board or with a ST development kit ? Did you use an application template available in TouchGFX Designer ? Or use one as source of inspiration to configure your project ? Are you using an OS ? How did you configure your display (and what kind of display is it ? ) ?

Hi,

I am working with a custom board, the CubeIDE is the latest version which generate the code of touchgfx and freertos. After upgrade, HAL_NVIC_SystemReset() is called , and it jump to the App code from boot, the screen show nothing but the backlight is normal as is expected.But after I put the power back on, the application work well.Do I need to deinit the LTDC or DMA2D peripheral before jump to app?

Hi @JJ.Lin and @Romain DIELEMAN 

I have a similar problem like this. Is there any must to do while jumping from boot to the app?

How can I stop working TouchGFX?
