3.4 Build Bootloader from Source
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:
 Refer to Build_F/W_Source for installing all prerequisite packages.
 Download the bootloader source codes:
$ git clone https://github.com/MediaTek-Labs/linkit-smart-uboot.git
 Change to the source folder:
$ cd linkit-smart-uboot
 Install the toolchain needed for building the bootloader:
$ sudo tar xjf buildroot-gcc342.tar.bz2 -C /opt/
 Since the toolchain is provided in 32-bit executables, you need to install additional
packages for execution on a 64-bit machine:
$ sudo dpkg --add-architecture i386
$ sudo apt-get update
$ sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386
 Start the compilation process:
$ make
 The resulted bootloader file is uboot.bin.
 You can rename it to lks7688.ldr for upgrading the system bootloader through a USB
drive.
