Avalon / Canaan Stock Firmware
Official Canaan firmware downloads for Avalon miners. Version history, AUC controller firmware, and installation instructions.
Overview
Canaan provides stock firmware for its Avalon miner series. Avalon miners use a unique architecture with separate AUC (Avalon USB Converter) controllers and miner modules, each requiring their own firmware. The control software runs on an external Raspberry Pi or AUC controller box.
Architecture Note: Unlike Antminer and Whatsminer, Avalon miners typically use external controllers (Raspberry Pi or AUC) running CGMiner or Avalon's control software. Firmware updates may involve both the controller and the miner modules.

Installation
Controller (Raspberry Pi) Setup
- Download the Avalon controller image for your model
- Flash to microSD card using Balena Etcher or
dd - Insert into Raspberry Pi and connect to AUC
- Power on — the controller auto-detects connected miners
- Access web UI at
http://<controller-ip>
Firmware Update via Web UI
- Access the controller web interface
- Navigate to System → Firmware Upgrade
- Upload the firmware image
- Click Update and wait for completion
- The controller and connected modules will restart
Module Firmware Update
Module firmware updates are pushed from the controller:
- Ensure the controller is running the latest firmware
- In the web UI, navigate to Modules → Update
- The controller pushes firmware to all connected Avalon modules
- Monitor progress in the web interface
Do not disconnect modules during firmware update. Interrupting a module update can leave the mining chips in an undefined state, requiring manual recovery.
CGMiner Configuration
Avalon miners use CGMiner as the mining software on the controller:
# Example CGMiner configuration
cgminer -o stratum+tcp://pool.example.com:3333 \
-u wallet_address.worker_name \
-p x \
--avalon-fan 40-100 \
--avalon-freq 500 \
--avalon-voltage 800Official Download Sources
