Ivan Davydov 1c274227b0 ramips: mt76x8: add support for Keenetic KN-3211
Keenetic KN-3211 is a 2.4 Ghz band 11n (Wi-Fi 4) Wi-Fi repeater, based on MT7628AN.

Specification:
- System-On-Chip: MT7628AN
- CPU/Speed: 575 MHz
- Flash-Chip: Winbond w25q256
- Flash size: 32768 KiB
- RAM: 64 MiB
- 1x 10/100 Mbps Ethernet
- 2x external, non-detachable antennas
- UART (J1) header on PCB (115200 8n1)
- Wireless No1 (2T2R): SoC Built-in 2.4 GHz 802.11bgn
- 3x LED, 1x button, 1x mode switch

Notes:
- The device supports dual boot mode
- The firmware partitions were concatenated into one
- The status button has been reassigned as the WPS button.

Flash instruction:
This device doesn't support sysupgrade, so the only way to flash OpenWrt image
is to use tftp recovery mode in U-Boot:

1. Configure PC with static IP 192.168.1.2/24 and tftp server.
2. Rename "openwrt-ramips-mt76x8-keenetic_kn-3211-squashfs-factory.bin"
   to "KN-3211_recovery.bin" and place it in tftp server directory.
3. Connect PC with the ethernet port, press the reset button, power up
   the router and keep button pressed until power led starts blinking.
4. Router will download file from server, write it to flash and reboot.

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.

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).
