Subject: ramips: add support for Fon FON2601
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
FON2601 is a wireless router.
Specification:
- SoC: Mediatek MT7620A (580MHz)
- RAM: 128 MiB
- ROM: 16 MiB SPI Flash
- Wireless:
for 11b/g/n (upto 300 Mbps): MT7620A built-in WMAC
for 11a/n/ac (upto 867 Mbps): MT7662E
- Ethernet LAN: 1 port, upto 100 Mbps
- Ethernet WAN: 1 port, upto 1000 Mbps
- USB: 1 port (USB 2.0 host)
- LEDs: 4 (all can be controlled by SoC's GPIO)
- buttons: 1 (Displayed as "WPS" on enclosure)
- serial port: 57600n8
pins: Vcc(3.3V), Rx, Tx, GND
(left to right, viewed from outside of board)
Installation (only available via UART):
1. download sysupgrade binary image by wget command
2. write sysupgrade binary image to Flash
command is:
mtd write sysupgrade.bin firmware
3. reboot
Important Notice:
Only one button is displayed as "WPS" on enclosure.
However, it is configured as "reset" (factory resetting feature).
