What do you want to achieve?
Hello everyone. It is my first time using the LVGL libraries to make a GUI for STM32MP257-DK. I am following the example in GitHub - lvgl/lv_port_linux: LVGL configured to work on Linux (Wayland, DRM, EGL, OpenGL, fbdev, X11 etc) · GitHub . More specifically the tutorial made for the STM32MP257-DK board. lv_port_linux/boards/stm32mp257f-dk/README.md at master · lvgl/lv_port_linux · GitHub
While using the wayland.defconfig works, it only uses the CPU for the graphics. As the STM32MP257FAK3 has a GPU I would like to use it aswell, hence why I am trying to launch the wayland_3d.defconfig configuration. Sadly, it does not launch when I write the “./lvglsim -f” in the STM32MP257-DK CLI. Instead, the CPU halts and restarts. Do you know what could be causing this? I can supply code snippets of the error if necessary.
UPDATE, THIS IS THE ERROR I GET AFTER “./lvglsim -f”:

I hope someone can help, thank you very much in advance!
Environment
- MCU/MPU/Board: STM32MP257-DK
- LVGL version: Pretty sure V10, as I downloaded it yesterday. From the github link at the top.
