Build the firmware from sources

This section describes how to build the firmware for LinkIt Smart 7688 and LinkIt Smart 7688 Duo from source codes.

Host environment

The following operations are performed under a Ubuntu LTS 14.04.3 environment. For a Windows or a Mac OS X host computer, you can install a VM for having the same environment:


In the Ubuntu system, open the Terminal application and type 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. Download OpenWrt CC source codes:

    $ git clone git://
  3. Prepare the default configuration file for feeds:

    $ cd openwrt
    $ cp feeds.conf.default feeds.conf
  4. Add the LinkIt Smart 7688 feed:

    $ echo src-git linkit >> feeds.conf
  5. Update the feed information of all available packages for building the firmware:

    $ ./scripts/feeds update
  6. Install all packages:

    $ ./scripts/feeds install -a
  7. Prepare the kernel configuration to inform OpenWrt that we want to build an firmware for LinkIt Smart 7688:

    $ make menuconfig

    ** Select the options as below: **

    - Target System: `Ralink RT288x/RT3xxx`
    - Subtarget: `MT7688 based boards`
    - Target Profile: `LinkIt7688`

    Save and exit (use the deafult config file name without changing it)

  1. Start the compilation process:

    $ make V=99
  2. After the build process completes, the resulted firmware file will be under bin/ramips/openwrt-ramips-mt7688-LinkIt7688-squashfs-sysupgrade.bin. Depending on the H/W resources of the host environment, the build process may take more than 2 hours.
