Color Frame Buffer Start Address missing.

[JanzTec-JP]

Hello STM-Community.
I am currently working on some project with the "LIZARD Board" from Actron and a 800*480 LCD-screen.

I followed the Instruction in https://support.touchgfx.com/docs/development/board-bring-up/how-to/03-display-internal
and also other "tutorials" but wasnt able to get it to work.

Now i finally noticed that the "Color Frame Buffer Start Address" in LTDC is missing...

I have no idea why that is the case and if this a bug in CubeIDE v.1.17.0 or something on my side.

Does anyone know what to do?

Hello @JanzTec-JP ,

 

How do you figure that the color frame buffer in LTDC is missing?

 

Can you look at the STM32U5G9J-DK2 TBS and compare it to your project? The STM32U5G9J-DK2 is also using LTDC, you can just change from double to single framebuffer in STM32CubeMX.

Hello @GaetanGodart 

 

I updated STM32CubeIDE to the latest version 1.18.1 and this bug resolved itself.
The missing entry instantly appeared after i migrated my project to this version and opened the .ioc to check.

 

I still dont know what caused this but it seems fixed now.

 

Thank you for your suggestion!
With best regards,
