Hello, I created a project on a STM32746g-DISCO board using Cube MX, added LVGL, and created the UI with Squareline. Unfortunately, I only get this picture even when I comment out ui\_init(). Does anyone know what might be causing this?

Now I’ve made the LVGL, UI, and TFT inits according to the MX\_inits and the display is black (in the UI, it’s simply set to a white background with a red box), the backlight is on.

Let’s try to make the display work without LVGL.

If you write some data to the frame buffer so you see it on the display?
