TouchGfx hardware acceleration libraries not included from CubeMx and CubeIde project

[rvminsta_01]

Hello

Project based on stm32u5g9 where I enabled TouchGfx in CubeMx settings. Layer 0 is configured to 800x600. I generate code from CubeMx. GPU2D and DMA2D are enabled and configured from CubeMx.

With TouchGfx Designer, I open the ApplicationTemplate.touchgfx.part generated or my ProjectName.touchgfx project, I see that screen dimensions are 800x480, I think it should be 800x600.

In TouchGfxDesigner, I add a screen and a box inside the screen, nothing more.

I generate code from TouchGfxDesigner.

In CubeIde, the only generated or added library I can see is :libtouchgfx-float-abi-hard.a.

I have other project generated by myself though directly from TouchGfxDesigner, chosing a STM32U5G9J-DK2 800x480 kit. Here I can see :libnemagfx-float-abi-hard.a and :libtouchgfxnema-float-abi-hard.a are included in CubeIde project.

In my code, I am trying to draw a scaled line, using ScalableImage, BitmapId, creating a dynamicBitmap.

Indeed the line is scaled and displayed in my display.

However the rendering time is very long, around 300 msec. I have defined RENDER_TIME_Pin, I can see the rendering time in oscilloscope.

Any help would be appreciated.

Regards.

Hello @rvminsta_01,

Can you provide the ioc file ?
