This is a MT7621-based device with 128MB NAND flash, 256MB RAM, and a USB port. The board has headers to attach console. In order for them to work two solder bridges near those pads need to be made. The defice has the following partition table: ``` 0x000000000000-0x000000080000 : "u-boot" 0x000000080000-0x000000100000 : "u-boot-env" 0x000000100000-0x000000140000 : "factory" 0x000000140000-0x000007e00000 : "firmware" 0x000007e00000-0x000008000000 : "panic-ops" ``` `firmware` partition contains UBI volumes. Unfortunately I accidentally wiped partition and I no longer have access to it. `firmware` partition contains 'secondary' U-Boot which is run by 'first' u-boot. It also contains various configuration partitions that include device info and MAC address. There also seems to be 'primary' and 'backup' set of 'main' volumes. U-boot has `mtkupgrade` command that just overrides data on firmware partitions. Firmware file provided by TP-Link cannot be used with that command. U-boot also has 'recovery' http server. Unfortunately I was not able to make it work with manufacturer's firmware. Manufacturer's firmware essentially contains multiple UBI volumes along with 'partition table'. Unfortunately I no longer can properly run manufacturer's firmware so I cannot at the moment try to a support for building 'factory' images. This patch adds support for initramfs image as well as sysupgrade image. This seems to be pretty standard MT7621 board otherwise.

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.

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 MacOSX 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 python3.6+ rsync subversion unzip which
Quickstart
-
Run
./scripts/feeds update -ato obtain all the latest package definitions defined in feeds.conf / feeds.conf.default -
Run
./scripts/feeds install -ato install symlinks for all obtained packages into package/feeds/ -
Run
make menuconfigto select your preferred configuration for the toolchain, target system & firmware packages. -
Run
maketo 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.
