Comfast CF-E538AC is an wall mounted access point with an
additional Ethernet LAN access port. It supports
802.11AC Wave2 MU-MIMO
Serial port access for debricking requires simple soldering of 4 pins.
Device specifications:
* SoC: MT7620DA @ 580MHz
* RAM: 64MiB DDR2
* Flash: 8iB SPI
* Wireless 2.4GHz (SoC): b/g/n
* Wireless 5Ghz (MT7612E): n/ac, 2x2 MU-MINO
* Ethernet (RTL8211F): 1× 1GbE, 802.3af PoE
* Ethernet (RTL8211F): 1× 1GbE
Flashing instructions:
* Upgrade using web interface
Debricking:
* Serial port can be soldered on top PCB (marked as 1)
(1: VCC, 2: GND, 3: TX, 4: RX)
* Use 3.3V, 115200 baud, 8n1
* Recovery only possible via TFTP
* Modified U-Boot environment does not allow recovery via serial
(will not commit it to flash)
* Bootloader will show a menu for 1 seconds
* Select 2: Load system code then write to Flash via TFTP.
