K868-A8 flashing configuration ?

[vincen]

Hi

What is the exact procedure to flash that device ? and please don't send me your useless youtube videos !! I have applied 12V on board (board starts well) I plugged the USB cable between my computer or my Home assistant system and the board but ESPHome never succeeds to communicate through the USB port to flash the board  Got no problem to flash the K868-AG and the K868-Uair but not that device..

Here is my basic code used for now:

Code:

substitutions:
  friendly_name: kincony-k868-a8

esphome:
  name: $friendly_name
  platform: ESP32
  board: esp32dev

logger:

web_server:

ota:

wifi:
  networks:
  - ssid: !secret wifi
    password: !secret wifi_passwd
  - ssid: !secret wifi_puppy
    password: !secret wifi_puppy_passwd
  ap:
    ssid: $friendly_name

captive_portal:

api:
  reboot_timeout: 120min

Thanks

Vincèn
