ESPHome LVGL Fails to Allocate #20
Description
Hello,
I am trying to use ESPHom'e LVGL graphics, but it is not working.
Without LVGL, this works (and I see the RGB test card):
display:
- platform: m5cores3_display
model: ILI9342
dc_pin: 35
id: m5cores3_lcd
auto_clear_enabled: false
show_test_card: trueHowever, when I add LVGL I get a boot loop:
lvgl:
# buffer_size: 25% # I tried this at 100%, 50%, and 25% always with the same result
displays:
- m5cores3_lcd
pages:
- id: main_page
widgets:
- label:
align: CENTER
text: 'Hello World!'
display:
- platform: m5cores3_display
model: ILI9342
dc_pin: 35
id: m5cores3_lcd
auto_clear_enabled: false
show_test_card: falseLog:
