Hi folks!
I have a Cheap Yellow Display (ESP32-2432S028) and while it works fine using lambda to put stuff on the screen, I would really like to use LVGL instead as that’s easier for my tiny brain to comprehend.
However, I can’t for the life of me even get a basic Hello World to display when using LVGL 
This is my ESPHome script:
esphome:
name: esphome-web-6d0fe4
friendly_name: yellow
min_version: 2024.11.0
name_add_mac_suffix: false
esp32:
board: esp32dev
framework:
type: arduino
logger:
level: DEBUG
api:
psram:
ota:
- platform: esphome
wifi:
ssid: "xxxx"
password: "xxxx"
spi:
- id: tft
clk_pin: GPIO14
mosi_pin: GPIO13
miso_pin: GPIO12
interface: hardware
lvgl:
display:
- platform: ili9xxx
id: coolscreen
model: TFT_2.4
cs_pin: GPIO15
dc_pin: GPIO2
invert_colors: false
update_interval: never
auto_clear_enabled: false
spi_id: tft
And this is the log output in ESPHome after uploading the script to the device:

The only hint is Component lvgl is marked FAILED: - which isn’t very helpful
Anyone have any hints? Or is LVGL just not possible on this $10 gizmo?
