Introduction

In short, this project is a deep modification of U-Boot 1.1.4 sources, mostly from TP-Link, but some code fragments were taken also from D-Link, Netgear, ZyXEL and Belkin. All these companies are using SDK from Qualcomm/Atheros which includes modified version of U-Boot 1.1.4.

You can download original sources from the following pages:

  • TP-Link GPL Code Center
  • D-Link GPL Source Code Support
  • NETGEAR Open Source Code for Programmers (GPL)
  • ZyXEL GPL-OSS
  • Belkin Open Source Code Center

The concept for this project came from another U-Boot modification, dedicated to a small and very popular TP-Link router - model TL-WR703N, which includes web fail safe mode: wr703n-uboot-with-web-failsafe. I was using it and decided to make my own version, which could have some improvements, additional capabilities, support for different models and work with all modern web browsers.

First version of this modification was introduced on OpenWrt forum in this thread, at the end of March 2013 and was dedicated only for TP-Link routers with Atheros AR9331 SoC. Now, it supports also models from different manufacturers, devices with Atheros AR934x, Qualcomm Atheros QCA953x, Qualcomm Atheros QCA955x and other (in the near future Qualcomm Atheros QCA956x and MediaTek MT762x) are under development.

You can find some information about previous versions of this project also on my blog, in this article. It is in Polish, but Google Translator will help you to understand it.

I tested this modification on most of these devices, with OpenWrt and OFW firmware. If you are not sure about the version of your device, please contact with me before you try to make an upgrade. Changing bootloader to a wrong version will probably damage your router and you will need special hardware to fix it, so please, be very careful.
