Rani Hod cbc2cdbb80 ramips: mt76x8: add support for Wodesys WD-R1208U 
This commit adds support for a dual-band AC1200 wall plug
manufactured by Shenzhen Century Xinyang Tech Co., Ltd.

SoC:     Mediatek MT7628AN (MIPS 24KEc single core, 580 MHz)
RAM:     128 MiB DDR2 (Hynix HY5PS1G1631C)
ROM:     8 MiB SPI NOR (Zbit ZB25VQ64ASIG)
Wired:   one FE RJ45 port (+ an unpopulated footprint for a 2nd)
WiFi:    Mediatek MT7612E
Ant.:    four 2 dBi external antennas (two 2.4GHz, two 5 GHz)
LEDs:    - Power    (green, always on)
         - 2.4G     (green, controlled by MT7628)
         - 5G       (green, controlled by MT7612)
         - Extender (green, GPIO 37, used as status LED)
         - LAN      (green/yellow, controlled by RT3050 ESW)
Buttons: WPS and reset (both connected to GPIO 38)
Power:   5V 2-pin JST-XH on main PCB
         110/220V AC to 5V 1.5A DC on auxiliary PCB
UART:    57600 8n1 3.3v, holes available on the PCB as J5
         pinout is (Gnd) (Tx) (Rx)
MAC:     1C:BF:CE:xx:xx:xx       (2.4 GHz, label)
         1C:BF:CE:xx:xx:xx + 1   (LAN)
         1C:BF:CE:xx:xx:xx + 2   (WAN, not in use)
         1C:BF:CE:xx:xx:xx + 3   (5 GHz)

Original firmware is Chaos Calmer 15.05.01 (kernel 3.10.108)
with a few custom packages and a non-LuCI web interface.
Telnet is enabled, requiring an unknown root password [1].
Root password is also needed to access the router via UART console,
but passwordless telnet can be enabled via a trivial web exploit [2]
and then the root password can be removed by editing `/etc/shadow`.

Installation: Upload `sysupgrade` binary via web interface at
  `http://192.168.188.1/settings.shtml`. Alternatively, remove
  root password and use u-boot menu to flash image via TFTP.

Notes:
- Device model in Chaos Calmer is "mtk-apsoc-demo".
- It is sold under several brands, e.g., Fenvi and Linkavenir.
  It is available in two colors: white and black.
- PCB is marked "WD206AD v1.0".
- Instead of a standard ethernet transformer, the PCB has a few tiny
  SMD coils.
- The housing is identical to the one used by a 2020 model,
  WD-R1203U, which is RTL8812-based. The older model has an FCC
  listing with external and internal images: ZNPWD-R1203U.
  The FCC listing contains a letter [3] claiming WD-R1203U and
  WD-R1208U are internally identical, but evidently they are not.

[1] root:$1$7rmMiPJj$91iv9LWhfkZE/t7aCBdo.0:18388:0:99999:7:::
    This is the same hash as in Wodesys WD-R1802U.
    There are other root password hashes in `/etc/shadow_sf` and
    `/etc/shadow_yn`.

OpenWrt logo

OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned.

Sunshine!

Download

Built firmware images are available for many architectures and come with a package selection to be used as WiFi home router. To quickly find a factory image usable to migrate from a vendor stock firmware to OpenWrt, try the Firmware Selector.

If your device is supported, please follow the Info link to see install instructions or consult the support resources listed below.

An advanced user may require additional or specific package. (Toolchain, SDK, ...) For everything else than simple firmware download, try the wiki download page:

Development

To build your own firmware you need a GNU/Linux, BSD or macOS system (case sensitive filesystem required). Cygwin is unsupported because of the lack of a case sensitive file system.

Requirements

You need the following tools to compile OpenWrt, the package names vary between distributions. A complete list with distribution specific packages is found in the Build System Setup documentation.

binutils bzip2 diff find flex gawk gcc-6+ getopt grep install libc-dev libz-dev
make4.1+ perl python3.7+ rsync subversion unzip which

Quickstart

  1. Run ./scripts/feeds update -a to obtain all the latest package definitions defined in feeds.conf / feeds.conf.default

  2. Run ./scripts/feeds install -a to install symlinks for all obtained packages into package/feeds/

  3. Run make menuconfig to select your preferred configuration for the toolchain, target system & firmware packages.

  4. Run make to build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the GNU/Linux kernel & all chosen applications for your target system.

Related Repositories

The main repository uses multiple sub-repositories to manage packages of different categories. All packages are installed via the OpenWrt package manager called opkg. If you're looking to develop the web interface or port packages to OpenWrt, please find the fitting repository below.

  • LuCI Web Interface: Modern and modular interface to control the device via a web browser.

  • OpenWrt Packages: Community repository of ported packages.

  • OpenWrt Routing: Packages specifically focused on (mesh) routing.

  • OpenWrt Video: Packages specifically focused on display servers and clients (Xorg and Wayland).
