STM32CubeMX + STM32F746G-DISCO

I'm trying to get working code from STM32CubeMX on STM32F746G-DISCO board. I'm using LwIP TCP/IP stack (which works fine - obtains IP address over DHCP) and STemWIN GUI library and there is the problem. LTDC has been properly configured but when I try to use any of STemWIN functions nothing happens - getting black screen. I'm using latest version of STM32CubeMX and SW4STM32. Maybe someone has working demo project with stemwin and lwip? Or someone know what is wrong with automatically generated project?

Hello

Obiala.Robert

,

Could you please provide more details on yourproject: your STemWin

configuration,

which Cube firmware package are you using?I recommend you to debug your project and try to identify where the code hangs.

Otherwise, share with us your .ioc file to help you more.

Best Regards

Imen

I uploaded test.ioc to sendspace

.

It's pure configuration from CubeMX, I only turned off SD card because it causes some conflicts and I changed resolution in Graphics (was wrong). Screen gets white (LTDC configuration), then black and nothing happened. As you can see there should be 'Hello world' string on the screen.

Debugging tells nothing - Breakpoint on GUI_Delay line is hit frequently, so it seems that everything works fine.
