FnNAS fnOS

This document explains how to install FnNAS fnOS (ARM public beta) on Radxa Orion O6 (CIX P1 SoC) and points to the upstream FnNAS install guide and help center.

Scope and Current Status
  • This document only applies to Radxa Orion O6 (CIX P1 SoC)
  • FnNAS support on Orion O6 is community-validated, not an officially maintained Radxa distribution
  • The ARM build of FnNAS fnOS is currently in public beta and may include instability, data loss, or functional issues. Test only on non-critical environments and back up important data beforehand
  • Read the FnNAS ARM Public Beta Disclaimer before installing

Prerequisites​

Before you begin, make sure:

  • The device BIOS is updated to a recent version: see BIOS Update
  • You have a USB flash drive with at least 16 GB capacity (USB 3.0 recommended)
  • You have an SSD for the fnOS system disk (recommended ≥ 64 GB)
  • You have a display, keyboard, mouse, and an Ethernet cable (wired network is recommended; pure Wi-Fi support is still unstable in the public beta)
  • You have read the FnNAS ARM Public Beta Disclaimer

1. Download the FnNAS Image for CIX P1​

Open the FnNAS fnOS ARM download page: FnNAS fnOS ARM Download Page.

Find the image that supports CIX P1 in the device support list:

  • Image category: UEFI ARM Installation Image ISO (file tag armsr)
  • That category explicitly lists CIX P1 as supported (along with Apple M-series virtualization, Phytium, and Huawei Kunpeng on UEFI ARM platforms)

After locating the image on the page, follow the on-page prompt to download the latest version yourself. Specific version and build numbers change with each public beta release; always trust the FnNAS ARM download page.

Verify the Image

After download, verify the MD5 hash published on the FnNAS page before writing it to the install media to avoid using a corrupted image.

2. Follow the Upstream FnNAS Tutorial to Install and Initialize​

Write the armsr ISO to a USB flash drive using any of the following tools:

  • Balena Etcher
  • Rufus (recommended on Windows)
  • dd (Linux / macOS)

Then follow the upstream FnNAS tutorial to complete the rest:

High-level steps:

  1. Plug the USB drive into Orion O6 and select the USB drive from the BIOS boot menu
  2. Choose Graphical Install in the installer menu
  3. Select the SSD used as the fnOS system disk and complete partitioning and Swap settings (system partition ≥ 64 GB recommended)
  4. Confirm the format prompt and start the installation
  5. Configure networking when prompted (wired + DHCP recommended)
  6. Remove the boot USB drive and reboot. Note the IP address assigned
  7. Open the IP address in a browser and complete device name, admin account, storage space, and other initialization steps
Differences From the Upstream Tutorial
  • The upstream FnNAS tutorial uses an x86 image for examples. This document uses the ARM public beta armsr ISO; follow the steps on this page
  • If the installer prompts you to disable Secure Boot, see Install Troubleshooting
  • After disabling Secure Boot, return to BIOS Device Manager → Platform Configuration → Compliance Configuration and confirm Enable ACPI SCMI is still enabled

3. Day-to-Day Use and Maintenance​

Day-to-day use, backup, remote access, file sharing, and App installation follow the same flow as the x86 version of fnOS. See the FnNAS help center:

4. Public Beta Issue Reports​

If you hit issues on the ARM public beta, please file them in the FnNAS Community ARM Section and include:

  • Device model (Radxa Orion O6) and BIOS version
  • fnOS image version and build number
  • Full reproduction steps and relevant logs
