Add support for COMFAST CF-EW72 V2
Hardware:
- SoC: Mediatek MT7621 (MT7621DAT or MT7621AT)
- Flash: 16 MiB NOR
- RAM: 128 MiB
- Ethernet: Built-in, 2 x 1GbE
- Power: only 802.3af PD on any port, injector supplied in the box
- PoE passthrough: No
- Wifi 2.4GHz: Mediatek MT7603BE 802.11b/g/b
- Wifi 5GHz: Mediatek MT7613BEN 802.11ac/n/a
- LEDs: 8x (only 1 is both visible and controllable, see below)
- Buttons: 1x (RESET)
Installing OpenWrt:
Flashing is done using Mediatek U-Boot System Recovery Mode
- make wired connection with 2 cables like this:
- - PC (LAN) <-> PoE Injector (LAN)
- - PoE Injector (POE) <-> CF-EW72 V2 (LAN). Leave unconnected to CF-EW72 V2 yet.
- configure 192.168.1.(2-254)/24 static ip address on your PC LAN
- press and keep pressed RESET button on device
- power the device by plugging PoE Injector (POE) <-> CF-EW72 V2 (LAN) cable
- wait for about 10 seconds until wifi led stops blinking and release RESET button
- navigate from your PC to http://192.168.1.1 and upload OpenWrt *-factory.bin firmware file
- proceed until router starts blinking with wifi led again (flashing) and stops (rebooting to OpenWrt)
MAC addresses as verified by OEM firmware:
vendor OpenWrt address
LAN lan\eth0 label
WAN wan label + 1
2g phy0 label + 2
5g phy1 label + 3
The label MAC address was found in 0xe000.
LEDs detailed:
The only both visible and controllable indicator is blue:wlan LED.
It is not bound by default to indicate activity of any wireless interfaces.
Place (WAN->ANT) | Num | GPIO | LED name (LuCI) | Note
-----------------|-----|-----------------------------------------------------------------------------------------
power | 1 | | | POWER LED. Not controlled with GPIO.
hidden_led_2 | 2 | 13 | blue:hidden_led_2 | This LED does not have proper hole in shell.
wan | 3 | | | WAN LED. Not controlled with GPIO.
hidden_led_4 | 4 | 16 | blue:hidden_led_4 | This LED does not have proper hole in shell.
lan | 5 | | | LAN LED. Not controlled with GPIO.
noconn_led_6 | 6 | | | Not controlled with GPIO, possibly not connected
wlan | 7 | 15 | blue:wlan | WLAN LED. Wireless indicator.
noconn_led_8 | 8 | | | Not controlled with GPIO, possibly not connected
mt76-phy0 and mt76-phy1 leds also exist in OpenWrt, but do not exist on board.
