Setting update_interval to never cause reboot loop

[lehovec]

For some reason, when I set to display component update_interval to never, it causes a reboot loop after flash. My config:

esphome:
  name: liligo-t5-47-epaper-plus
  platformio_options:
    board_dir: boards
    #include https://github.com/Xinyuan-LilyGO/LilyGo-EPD47/blob/master/platformio/boards/lilygo-t5-47-plus.json as custom board
    board: lilygo-t5-47-plus

esp32:
  variant: esp32s3
  board: lilygo-t5-47-plus

  framework:
    type: arduino

#.....other conf code

i2c:
  sda: GPIO17
  scl: GPIO18
  scan: false
  id: bus_a

external_components:
  - source: github://nickolay/esphome-lilygo-t547plus
    components: ["t547"]

text_sensor:
  - platform: homeassistant
    entity_id: weather.forecast_domov
    id: fc_weather
    internal: true
    on_value: # Actions to perform once data for the last sensor has been received
      then:
        - component.update: t547_display

display:
- platform: t547
  id: t5_display
  update_interval: 30s
  lambda: |-
    it.line(0, 0, 960, 540);

update_interval: never works fine for me if I use https://github.com/nickolay/esphome-lilygo-t547plus/blob/main/basic.yaml as base:

# The following goes after `wifi: !include wifi-secrets.yaml` from basic.yaml

display:
  - platform: t547
    id: t547_display
    # rotation: 180
    update_interval: never
    lambda: |-
      it.line(0, 0, 960, 540);

i2c:
  sda: GPIO17
  scl: GPIO18
  scan: false
  id: bus_a

external_components:
  - source: github://nickolay/esphome-lilygo-t547plus
    components: ["t547"]

text_sensor:
  - platform: homeassistant
    entity_id: weather.forecast_home
    id: fc_weather
    internal: true
    on_value: # Actions to perform once data for the last sensor has been received
      then:
        - component.update: t547_display

When I try lilygo-t5-47-plus.json without pinning old versions, I do get the loop boot UNLESS I use fast_connect: true in the wifi: section. The reason for rebooting is the task watchdog misbehaving:

...and so on...

I don't have much time to debug this further...

I finally tracked down the task watchdog crash to ARDUINO_RUNNING_CORE=0 (https://github.com/esphome/issues/issues/5317), you can try changing it to 1 in the board's json to see if it works.
