The goal of building the Armbian operating system from source is to create a highly configurable base image, with granular control over kernel features, that can be written on an eMMC or SD card and boots directly into an operational state.
The process to build the Armbian image for the RockPro64 board is mostly automated and follows Armbian best practices.
It makes use of the Docker containers to perform the build process:
The following build instructions have been tested both on Debian-based Linux systems and within Windows PowerShell.
- Regular computer with x86/x64 architecture, 4GB+ memory, 4+ cores
- minimum of 25 GB free space on a fast drive, preferrably SSD
- any operating system that can run Docker containers is supported
To set up and run the build environment in the virtual machine, the following software needs to be installed:
All sources and build scripts are contained in this repository, which needs to be cloned locally. The following commands are executed in the command line, either the Linux terminal or Windows PowerShell.
In Linux you can directly run
make, while in Windows PowerShell you need to run the build script directly with
sh. In the following instructions, Windows users just replace
- Clone the BitBoxBase repository to a local directory.
git clone https://github.com/digitalbitbox/bitbox-base.git cd bitbox-base/armbian
The initial system configuration is set on build and can be altered by setting build options in the file
Available options are described directly in the file and are set to default values. A few examples of build options you can set:
BASE_BITCOIN_NETWORK: set to
BASE_HOSTNAME: set it to
aliceand your BitBoxBase will be visible as
alice.localwithin your network
BASE_AUTOSETUP_SSD: set to
trueto automatically initialize the SSD on first boot
BASE_OVERLAYROOT: set to
trueto make the root filesystem read-only
- …and many more.
To preserve a local configuration, you can copy the file to
build-local.conf in the same directory. This file is excluded from Git source control and overwrites options from
Now the operating system image can be built. The whole BitBoxBase configuration is contained in
customize-armbian-rockpro64.sh and executed in a
chroot environment at the end of the build process.
Note: you might need use
sudo for all
make commands, depending on your Docker configuration.
- Start the initial build process.
- The resulting image is available in
bin/img-armbianand can be written to eMMC or SD card using a program like Etcher. On the Linux command line you can use
dd: once the target medium is connected to your computer, get the device name (e.g.
/dev/sdb). Check it carefully, all data on this device will be lost!
lsblk sudo dd if=bin/img-armbian/Armbian_5.77_Rockpro64_Debian_stretch_default_4.4.176.img of=/dev/sdb bs=64K conv=sync status=progress sync
- After initial build, you can update the image with an adjusted system configuration script, without building Armbian from scratch:
- To clean up and remove the build environment, run
