Device won't start or connect (ESP32S3)

[manziman]

Hi, I'm new to ESPHome and Home Assistant in general. I tried following the tutorials in the ESPHome docs and built my config using the example files here, but I cannot get the device to start properly or connect. Here's my config (you can see which board I'm using there):

  # Please use "JK04" if you have some old JK-BMS <= hardware version 3.0 (f.e. JK-B2A16S hw 3.0, sw. 3.3.0)

When I flash the device with this config, all I get is some vague fast boot message over and over again in the terminal:

[17:37:19]ESP-ROM:esp32s3-20210327
[17:37:19]Build:Mar 27 2021

[17:37:19]load:0x3fce3808,len:0x162c
[17:37:19]ets_loader.c 78 

To me this appeared to be a boot loop. On another forum I found a potential solution by changing the flash mode in the esphome config:

esphome:
  name: ${name}
  comment: ${device_description}
  project:
    name: "syssi.esphome-jk-bms"
    version: 1.5.0
  platformio_options:
    board_build.flash_mode: dio

This at least got rid of the above boot loop, but now I get this output, which simply hangs on the last line and never proceeds - no helpful log output:

Anyone have any ideas what's going on?

Please replace the ESP32S3 with a full featured ESP32. I guess this will fix the issue. Unfortunately I don't know the relevant differences of the ESP models to explain the root cause.

Hi, for me it's working with esp32-s3 (this model: https://www.waveshare.com/wiki/ESP32-S3-Pico) if you want I can attach here my yaml config
