Installation
------------
1. Rename OpenWrt initramfs image to test.bin and place it on tftp server
with IP 192.168.0.5
2. Attach UART, switch on the router and interrupt the boot process by
pressing 't'
3. Load and run OpenWrt initramfs image:
tftpboot
bootm
4. Once inside OpenWrt, switch to the first boot image:
fw_setenv BootImage 0
5. Run 'sysupgrade -n' with the sysupgrade OpenWrt image
Back to Stock
-------------
1. Run in the OpenWrt shell:
fw_setenv BootImage 1
reboot
Recovery
--------
1. Press Reset button and power on the router
2. Navigate to U-Boot recovery web server (http://192.168.0.1/) and upload
the OEM firmware
MAC addresses
-------------
+---------+-------------------+-------------------+-------------+
| | MAC example 1 | MAC example 2 | Algorithm |
+---------+-------------------+-------------------+-------------+
| label | 68:ff:7b:xx:xx:f4 | 50:d4:f7:xx:xx:da | label |
| LAN | 68:ff:7b:xx:xx:f4 | 50:d4:f7:xx:xx:da | label |
| WAN | 72:ff:7b:xx:xx:f5 | 54:d4:f7:xx:xx:db | label+1 [1] |
| WLAN 2g | 68:ff:7b:xx:xx:f4 | 50:d4:f7:xx:xx:da | label |
| WLAN 5g | 68:ff:7b:xx:xx:f6 | 50:d4:f7:xx:xx:dc | label+2 |
+---------+-------------------+-------------------+-------------+
label MAC address was found in factory at 0x165 (text format
xx:xx:xx:xx:xx:xx).
Notes
-----
[1] WAN MAC address:
a. First octet of WAN MAC is differ than others and OUI is not related
to TP-Link company. This probably should be fixed.
b. Flipping bits in first octet and hex delta are different for the
different MAC examples:
+-----------------+----------------+----------------+
| | Example 1 | Example 2 |
+-----------------+----------------+----------------+
| LAN | 68 = 0110 1000 | 50 = 0101 0000 |
| MAC (1st octet) | ^ ^ ^ | |
+-----------------+----------------+----------------+
| WAN | 72 = 0111 0010 | 54 = 0101 0100 |
| MAC (1st octet) | ^ ^ ^ | ^ |
+-----------------+----------------+----------------+
| HEX delta | 0xa | 0x4 |
+-----------------+----------------+----------------+
| DEC delta | 4 | 4 |
+-----------------+----------------+----------------+
c. DEC delta is a constant (4). This looks like a mistake in OEM
firmware and probably should be fixed.
Based on the above, I decided to keep correct OUI and make WAN MAC =
label + 1.
[2] Bootloaders
The device contains 3 bootloaders:
- First U-Boot: U-Boot 1.1.3 (Mar 18 2019 - 12:50:24). The First U-Boot
located on NAND Flash to load next full-feature Uboot.
- Main U-Boot + its backup: U-Boot 1.1.3 (Mar 18 2019 - 12:50:29). This
bootloader includes recovery webserver. Requires special uImages to
continue the boot process:
0x00 (os0, os1) - firmware uImage
0x40 (os0, os1) - standalone uImage (OpenWrt kernel is here)
- Additionally, both slots of the original TP-Link firmware contains
Image U-Boot: U-Boot 1.1.3 (Oct 16 2019 - 08:14:45). It checks image
magics and CRCs. We don't use this U-Boot with OpenWrt.

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.
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.
