## What does this project do? ### Purpose of This Repository
- Builds custom **kernel**, **image** or a **distribution** optimized for low-resource hardware, The **Armbian Linux Build Framework** creates minimal, efficient, and fully [customizable operating system images](https://docs.armbian.com/#key-features) based on **Debian** or **Ubuntu**. It is designed specifically for **low-resource single board computers (SBCs)** and other embedded devices.
- 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 This toolchain compiles a custom **Linux kernel**, **bootloader**, and **root filesystem**, providing fine-grained control over:
### Requirements for self hosted - Kernel versions and configuration
- Bootloader selection and customization
- Filesystem layout and compression
- Additional firmware, overlays, and device trees
- System optimizations for performance and size
- x86_64 / aarch64 / riscv64 machine The framework supports **native**, **cross**, and **containerized** builds for multiple architectures (`x86_64`, `aarch64`, `armhf`, `riscv64`), and is suitable for development, testing, production deployment, or automation pipelines.
- at least 8GB (less for non-[BTF](https://docs.kernel.org/bpf/btf.html) builds) of memory and ~50GB of disk space for VM, container, or bare-metal installation
- **Armbian / Ubuntu Jammy 22.04.x** for native building or any Docker capable Linux for containerised
- **Windows 10/11 with WSL2 subsystem** running Armbian / Ubuntu Jammy 22.04.x
- Superuser rights (configured sudo or root access).
- Make sure your system is up-to-date! Outdated Docker binaries, for example, can cause trouble
For stable branch use `--branch=v25.05` It ensures **consistency across devices** while remaining modular and extensible through a variety of configuration files, templates, and user patches.
### Quick Start
```bash ```bash
apt-get -y install git git clone https://github.com/armbian/build
git clone --depth=1 --branch=main https://github.com/armbian/build
cd build cd build
./compile.sh ./compile.sh
``` ```

- Interactive graphical interface. ### Build Host Requirements
- 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 - **Supported Architectures:** `x86_64`, `aarch64`, `riscv64`
- **System:** VM, container, or bare-metal with:
- **≥ 8GB RAM** (less with `KERNEL_BTF=no`)
- **~50GB disk space**
- **Operating System:**
- Armbian / Ubuntu 24.04 (Noble) for native builds
- Any Docker-capable Linux for containerized setup
- **Windows:** Windows 10/11 with WSL2 running Armbian / Ubuntu 24.04
- **Access:** Superuser rights (`sudo` or `root`)
- **Important:** Keep your system up-to-date — outdated tools (e.g., Docker) can cause issues.
