TP-Link EAP225 v1 is an AC1200 (802.11ac Wave-1) ceiling mount access point.
Device specifications:
* SoC: QCA9563 @ 775MHz
* RAM: 128MiB DDR2
* Flash: 16MiB SPI-NOR
* Wireless 2.4GHz (SoC): b/g/n, 2x2
* Wireless 5Ghz (QCA9882): a/n/ac, 2x2
* Ethernet (AR8033): 1× 1GbE, 802.3at PoE
Flashing instructions:
* Ensure the device is upgraded to firmware v1.4.0
* Exploit the user management page in the web interface to start telnetd
by changing the username to `;/usr/sbin/telnetd -l/bin/sh&`.
* Immediately change the malformed username back to something valid
(e.g. 'admin') to make ssh work again.
* Use the root shell via telnet to make /tmp world writeable (chmod 777)
* Extract /usr/bin/uclited from the device via ssh and apply the binary
patch listed below. The patch is required to prevent `uclited -u` in
the last step from crashing.
* Copy the patched uclited binary back to the device at /tmp/uclited
(via ssh)
* Upload the factory image to /tmp/upgrade.bin (via ssh)
* Run `chmod +x /tmp/uclited && /tmp/uclited -u` to install OpenWrt.

To make sure the correct file is patched, the following MD5 checksums
should match the unpatched and patched files:

Debricking:
* Serial port can be soldered on unpopulated 4-pin header
(1: TXD, 2: RXD, 3: GND, 4: VCC)
* Bridge unpopulated resistors running from pins 1 (TXD) and 2 (RXD).
Do NOT bridge the pull-down for pin 2, running parallel to the
header.
* Use 3.3V, 115200 baud, 8n1
* Interrupt bootloader by holding CTRL+B during boot
* tftp initramfs to flash via the LuCI web interface

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!
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.
