STM32 Baremetal application only Renders to part of the screen about lvgl HOT 5 CLOSED

The solution above fixes this issue thank you @kisvegabor 💯

Update, I managed to get LVGL to work! however not completely as we expect. So now It does render but somehow my code drops a part of the screen.

Here is how I am initializing the screen now

/*Function to initialize the screen as a LVGL element*/
void screen_init(void){
	lv_color_t *draw_buf1;
	lv_color_t *draw_buf2;

	bsp_lcd_init();

	draw_buf1 = (lv_color_t*)bsp_lcd_get_draw_buffer1_addr();
	draw_buf2 = (lv_color_t*)bsp_lcd_get_draw_buffer2_addr();

	//Init LVGL
	lv_init();

	//Init LVGL with our screen size
	lv_display_t * disp = lv_display_create(BSP_LCD_ACTIVE_HEIGHT, BSP_LCD_ACTIVE_WIDTH);

	//Initialize and set a buffer
	lv_display_set_buffers(disp, draw_buf1, draw_buf2, ((10UL * 1024UL) / 2), LV_DISPLAY_RENDER_MODE_PARTIAL);

	//Set a flush callback so lvgl can draw to our screen
	lv_display_set_flush_cb(disp, lcd_flush_cb);

	lv_display_set_rotation(disp, LV_DISPLAY_ROTATION_90);

	lv_display_set_color_format(disp, LV_COLOR_FORMAT_RGB565);
}

Amazing I see elements on the screen but part of it is cut out see below.

As you can see my base driver can use the whole screen but now when I hand over to LVGL it uses only a part of the screen, any help would be much appreciated.

The clipping issue happens because you call lv_display_set_rotation(disp, LV_DISPLAY_ROTATION_90);. With this LVGL will swap the horizontal and vertical resolution so you also need to configure your display to this orientation.

In ILI9341 it can be set with the ADDRESS_MODE (0x36) command.
