## What does this project do?
- Builds custom kernel, image or a distribution optimized for low-resource hardware,
- Include filesystem generation, low-level control software, kernel image and bootloader compilation,
- Provides a consistent user experience by keeping system standards across different platforms.
## Getting started
### Basic requirements
- x86_64 or aarch64 machine with at least 2GB of memory and ~35GB of disk space for a virtual machine, [WSL2](https://learn.microsoft.com/en-us/windows/wsl/install), container or bare metal installation
- Ubuntu Jammy 22.04.x amd64 or aarch64 for native building or any Docker capable amd64 / aarch64 Linux for containerised
- Superuser rights (configured sudo or root access).
- Make sure all your system components are up-to-date. Outdated Docker binaries, for example, can cause trouble.
### Start with the build script
```bash
apt-get -y install git
git clone --depth=1 --branch=main https://github.com/armbian/build
cd build
./compile.sh
```
### BUILD Allwinner H616 quad core 2GB RAM SoC WiFi （blueberry）
### 构建Allwinner H616四核2GB RAM SoC WiFi（蓝莓）
```bash
apt-get -y install git
git clone --depth=1 --branch=main https://git.aixiao.me/aixiao/build.git
./compile.sh build BOARD=blueberry BRANCH=legacy BUILD_DESKTOP=no BUILD_MINIMAL=yes KERNEL_CONFIGURE=yes RELEASE=bookworm
```
- Interactive graphical interface.
- Prepares the workspace by installing the necessary dependencies and sources.
- It guides the entire process and creates a kernel package or a ready-to-use SD card image.
### Build parameter examples
Show work-in-progress areas in interactive mode:
```bash
./compile.sh EXPERT="yes"
```
Build minimal CLI Armbian Focal image for Orangepi Zero. Use modern kernel and write image to the SD card:
```bash
./compile.sh \
BOARD=orangepizero \
BRANCH=current \
RELEASE=focal \
BUILD_MINIMAL=yes \
BUILD_DESKTOP=no \
KERNEL_CONFIGURE=no \
CARD_DEVICE="/dev/sdX"
```
