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

Host environment

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:


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 -b lede-17.01 linkit-smart-7688-lede
    git clone
  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.
