Armbian provides stable builds with long-term support as well as rolling releases with automated nightly builds of maintained targets. The project uses a strict release pipeline with code signing for image authentication, and each download includes .sha files for integrity verification and .asc files for cryptographic authentication. This focus on security ensures users can trust the images they download.
Tailored configurations for specific system-on-chips (SoCs) like Rockchip, Allwinner, and Broadcom.
1. User selects board, kernel version, release (Jammy, Bookworm, etc.) 2. Framework fetches: - Upstream kernel (or vendor BSP kernel) - U‑Boot for the board - Rootfs from debootstrap (arm64/armhf) 3. Applies hundreds of board‑specific patches (DRM, USB, Ethernet, audio codecs) 4. Cross‑compiles kernel, modules, U‑Boot 5. Creates chroot rootfs, installs kernel + modules, applies Armbian tweaks - armbian-firstlogin service - zram, log2ram, cpufrequtils - RTC, I2C, SPI overlays via `armbian-config` 6. Generates raw image with partition table, writes bootloader to offset 7. Compresses with `xz` (fast) or `zstd` (smaller/decompression speed) armbian iso
Armbian employs a unique kernel strategy compared to typical distributions:
Based on Debian. This flavor prioritizes rock-solid stability and low resource usage. It is ideal for servers, Pi-holes, and home automation. Armbian provides stable builds with long-term support as
The primary download portal is armbian.com/download . Navigate to your specific board model, and you’ll see a table of available images showing distribution, variant, type, kernel version, size, and direct download link. For example, an Orange Pi One user would see options for Ubuntu 24.04 Xfce Desktop (947 MB) or Debian 13 Minimal CLI (283 MB).
Freeze kernel updates to protect critical server deployments from breaking. Conclusion Framework fetches: - Upstream kernel (or vendor BSP
Armbian is a Linux distribution based on Debian or Ubuntu, explicitly optimized for ARM development boards. It is not merely a generic port; it focuses on providing a stable, fast, and secure base system, incorporating custom kernels, optimized drivers, and essential SBC utilities.
Includes a pre-installed desktop environment (like XFCE or GNOME) and essential user applications. Best for media centers or desktop replacement.
The Armbian ISO is built around a philosophy of
