TouchGFX Canvas Widgets not rendering on STM32N655 custom board

[Gowri_M]

Hi,

I am using TouchGFX 4.26.1 on a custom STM32N655x0 board. Most widgets (Box, Text, Button, SVG, Slider, etc.) render correctly, but Canvas Widgets such as Line, Circle, Shape, and the graph plot lines are not rendered. The graph background/grid is visible, but the plotted lines are missing.

The same TouchGFX project works correctly on the STM32N657-DK, but not on the STM32N655 custom board.

Is there any known limitation or additional configuration required for Canvas Widgets/NemaGFX/NeoChrom GPU2D on STM32N655? Are there any differences in Canvas Widget support between STM32N655 and STM32N657?

I've attached screenshots of the designed UI and the actual output on the custom board.

Hello ​@Gowri_M.

When you say the same TouchGFX project, do you mean that the exact same software is loaded onto the board, or only that the GUI is the same?
If the board setup is different, it could sound like there is an issue with your MPU configuration.

Best regards,
Johan
