This feeds holds everything a firmware of LinkIt Smart 7688 (Duo) needs to be composed of.

The following operations have been tested on Ubuntu 16.04.2 LTS. For a Windows or a Mac OS X host computer, you can install a VM for having the same environment by:

• Downloading Ubuntu 16.04.2 LTS image from http://www.ubuntu.com.
• Install this image with VirtualBox (http://virtualbox.org) on the host machine. 50GB disk space reserved for the VM is recommanded.

In Ubuntu system, open Terminal and execute the following commands:

1. Install prerequisite packages for building the firmware:

   sudo apt-get install git g++ make libncurses5-dev subversion libssl-dev \
       gawk libxml-parser-perl unzip wget python xz-utils

2. Get LEDE source code and this feed:

   cd /to/path/you/preferred
   git clone https://git.lede-project.org/source.git -b lede-17.01 linkit-smart-7688-lede
   git clone https://github.com/changyuheng/linkit-smart-7688-feed.git

3. Prepare the configuration file for feeds:

   cd linkit-smart-7688-lede
   cp ../linkit-smart-7688-feed/.lede/feeds.conf .

4. Update and install all feeds:

   ./scripts/feeds update -a
   ./scripts/feeds install -a

5. Prepare the configuration file for building system:

   cp ../linkit-smart-7688-feed/.lede/.config .

6. Start the compilation process:

   make -j4 V=99

   Release N in -jN with the number of your CPU thread count. Depending on the H/W resources of the host environment, the build process may take more than 2 hours.

7. After the build process completes, the resulted firmware file will be saved at bin/targets/ramips/mt7688/lede-ramips-mt7688-LinkIt7688-squashfs-sysupgrade.bin.

8. You can use this file to do the firmware upgrade through the Web UI. Or rename it to lks7688.img for upgrading through a USB drive.
