ramips: add support for Netcore NW5212
This patch adds support for Netcore NW5212, provided by some carrier in
China.
Specifications:
--------------
* SoC: Mediatek MT7620A
* RAM: 128MB DDR2
* Flash: 16MB SPI NOR flash (Winbond W25Q128BV)
* WiFi 2.4GHz: builtin
* Ethernet: builtin
* LED: Power, WAN, LAN 1-4, WiFi
* Buttons: Reset (GPIO 13)
* UART: Serial console (57600 8n1)
* USB: 1 x USB2
Installation:
------------
The router comes with OpenWrt 14.07 built with MTK SDK. However, as the
modem is provided by carriers, so the web interface is highly minimized and
only contains a static page with no interaction options.
There are two possible ways to gain the access.
1) Open the shell and use a UART2USB convert to gain TTY access. Please
notice you have to remove resistance R54 at the back of the board
otherwise you won't be able to input anything.
2) Use built-in backdoor. Access http://192.168.1.1/cgi-bin/_/testxst to
start dropbear service at port 9122. Be warned the software is super
old and only diffie-hellman-group1-sha1, diffie-hellman-group14-sha1,
kexguess2@matt.ucc.asn.au is support, you may not be able to connect it
with an up-to-date ssh client.
After you can control the device, flash the firmware as usual. Here are
some hints for that.
Option 1 (via original firmware):
1) Setup HTTP server on your computer, for example:
python3 -m http.server
2) Connect to the route and flash:
cd /tmp
wget http://<your-computer-host>/<your-firmware-name>
mtd -r write <your-firmware-name> firmware
Option 2 (replacing u-boot via breed):
1) Download breed-mt7620-reset13.bin from https://breed.hackpascal.net/
2) Setup HTTP server on your computer, for example:
python3 -m http.server
You can skip this step if your breed is already accessible from HTTP,
since the original wget does not support HTTPS.
3) Connect to the route and flash breed:
cd /tmp
wget http://<your-computer-host>/breed-mt7620-reset13.bin
mtd write breed-mt7620-reset13.bin Bootloader
4) Reboot. Hold reset key or press any key in TTY to enter breed.
5) Access breed web interface (http://192.168.1.1/). Choose the flash
layout to be 0x50000 and flash new firmware.
MAC addresses:
-------------
There are three MACs stored in factory, as in MT7620A reference design:
source address usage
0x4 label WLAN
0x28 label MAC 1
0x2e label + 1 MAC 2
However, the OEM firmware only uses one single MAC (label) for all
interfaces, probably a misconfiguration.
