Build Firmware
We usually use Debian and Ubuntu but many other distributions should also work. It is also possible to build on OSX. Building firmware directly on a Windows platform is not supported. However, if all you have available is a windows machine then we would recommend to set up a linux based virtual machine. Note: the following build was made on Ubuntu 16.04.5 LTS running 4.15.0-43 kernel.
Once you have a Linux OS running install the following prerequisite packages (some are optional):
sudo apt-get update sudo apt-get install git git-doc subversion build-essential flex wget gawk unzip man file python2.7 zlib1g-dev libssl-dev libncurses5-dev
Get the latest sources from 8devices OpenWRT branch:
git clone -b openwrt-19.07-ar71xx-4.14 https://github.com/8devices/openwrt-8devices rambutan cd rambutan
The easiest way is simply to execute a build script and wait until firmware will be built.
./build.sh rambutan
Building is a CPU heavy process and may take a long time depending on your CPU capabilities.
Once finished the compiled firmware image ending with rambutan-squashfs-factory.ubi
will be placed under bin/targets/ar71xx/nand/
directory.
Faster building
If you need a firmware image that contains packages that are not in the default image, but available in http://pkg.8devices.com repository - use Image Builder. No cross-compiling is required so build process is fast. The following example uses v2.9 release, we recommend using the latest available when building.
wget "http://pkg.8devices.com/rambutan/v2.9/OpenWrt-8devices-ImageBuilder-v2.9-ar71xx-nand.Linux-x86_64.tar.bz2" tar -xjvf OpenWrt-8devices-ImageBuilder-v2.9-ar71xx-nand.Linux-x86_64.tar.bz2 cd OpenWrt-8devices-ImageBuilder-v2.9-ar71xx-nand.Linux-x86_64/ mkdir files
You may place additional files if you'd like to include them into your firmware image. Thus the mkdir files
step and the additional argument FILES=files/
in our command below is optional.
For example, the following command adds luci tmux kmod-fs-ntfs packages, copies contents of files/
directory to our .bin
firmware image and also removes ppp ppp-mod-pppoe kmod-pppoe kmod-pppox packages from our default firmware image:
make image PROFILE=RAMBUTAN PACKAGES="luci tmux kmod-fs-ntfs -ppp -ppp-mod-pppoe -kmod-pppoe -kmod-pppox" FILES=files/
