I have just received the KC868-M16-V2.1 board with PoE module.

I am able to power the board ok with PoE. however I am unable to get ESPHome to connect via Ethernet.

ESPHome config is

Code:
ethernet:
  type: LAN8720
  mdc_pin: GPIO23
  mdio_pin: GPIO18
  clk_mode: GPIO17_OUT
  phy_addr: 0


I have also added static IP as follows:

Code:
ethernet:
  type: LAN8720
  mdc_pin: GPIO23
  mdio_pin: GPIO18
  clk_mode: GPIO17_OUT
  phy_addr: 0

  manual_ip:
    static_ip: 192.168.85.24
    gateway: 192.168.85.1
    subnet: 255.255.255.0
    dns1: 192.168.85.1


Getting errors about IP when using DHCP
Code:
[16:51:12][I][ethernet:248]: Starting ethernet connection
[16:51:12][W][component:157]: Component ethernet set Warning flag: waiting for IP configuration

When using StaticIP it looks promising
Code:
[16:51:12][I][ethernet:259]: Connected via Ethernet!
[16:51:12][C][ethernet:515]:   IP Address: 192.168.85.24
[16:51:12][C][ethernet:516]:   Hostname: 'energy-monitor'
[16:51:12][C][ethernet:517]:   Subnet: 255.255.255.0
[16:51:12][C][ethernet:518]:   Gateway: 192.168.85.1
[16:51:12][C][ethernet:523]:   DNS1: 192.168.85.1
[16:51:12][C][ethernet:524]:   DNS2: 0.0.0.0
[16:51:12][C][ethernet:536]:   MAC Address: E4:65:B8:6A:91:FC
[16:51:12][C][ethernet:537]:   Is Full Duplex: YES
[16:51:12][C][ethernet:538]:   Link Speed: 100

However it is unable to be seen on the network at all.

I have tried different cables and ports on my network switch.

A full reboot of the unit sees the same errors in the logs.

Sorry what is "re power"

I rebooted the board yes.

I will test now removing the PoE board and use the power adapter to power the board.
Yes same errors with the PoE board removed and using the power brick that came with the unit. After flashing I got the error, powered the unit off and reconnected after 20 seconds and the same error about unable to get IP.

If I put that ethernet cable into my computer it connects to the ethernet and gets an IP ok.

re power on = power off board -> power on board.
