MAC addresses:
- label/LAN = 'option macaddr' from factory tddp partition
- WAN = label MAC + 1
Installation:
Split initramfs into 2 parts for writing to the kernel and rootfs
partitions on live device, leave http server up for sysupgrade.
dd if=initramfs-kernel.bin of=kernel-part.bin bs=64k count=24
dd if=initramfs-kernel.bin of=rootfs-part.bin bs=64k skip=24
md5sum kernel-part.bin rootfs-part.bin
python3 -m http.server -d . 8080
Downgrade to TP-Link firmware v1.3.1 or less if running v1.3.2.
From the web UI, open "System Tools" and select "Diagnostics".
Enable "Remote Assistance" and login as root.
tplink_label_mac=01:23:45:67:89:AB
tplink_username=admin
echo -n "$tplink_label_mac$tplink_username" | md5sum | cut -c1-16
ssh \
-o "KexAlgorithms=+diffie-hellman-group1-sha1" \
-o "HostKeyAlgorithms=+ssh-rsa" \
root@192.168.0.1
Download partial initramfs binaries to /tmp and verify checksums match.
cd /tmp
wget http://192.168.0.20:8080/kernel-part.bin
wget http://192.168.0.20:8080/rootfs-part.bin
md5sum kernel-part.bin rootfs-part.bin
Write partial initramfs binaries to kernel and rootfs.
mtd -e kernel write kernel-part.bin kernel
mtd -r -e rootfs write rootfs-part.bin rootfs
Login to OpenWrt initramfs as root.
ssh root@192.168.1.1
Erase firmware partition and perform sysupgrade.
mtd erase firmware
sysupgrade -n -p http://192.168.1.111:8080/squashfs-sysupgrade.bin

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 python3.8+ 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.
