The following operations are performed under an 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:
Download the bootloader source codes:
git clone https://github.com/AcSiP/linkit-smart-7688-uboot.git
Change to the source folder:
cd linkit-smart-7688-uboot
Install the toolchain (install to path /opt) 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 +6:i386
Start the compilation process:
make
Bootloader filename is uboot.bin.
You can rename it to “lks7688.ldr” for upgrading the system bootloader
through a USB drive
.
