Updating your Avalon Nano 3
The Nano 3 runs Canaan’s open-source Avalon_Nano3s firmware on the Kendryte K230 platform. It reaches its web interface at the default IP 192.168.168.168 with the factory login root / root, broadcasts an AP-mode SSID like avalon_nano_XXXX for first setup, and exposes the CGMiner API on TCP port 4028. Update it three ways: the Avalon Remote / Avalon Family mobile app (one-tap match-and-install), the web UI Upgrade page, or a signed .swu uploaded to the built-in SWUpdate server on port 9090 (RSA-verified). Older Nano 3 builds carried a timezone-CGI security bug and a 24-day uptime crash, so keeping the unit on Canaan’s current build matters. Match the firmware to the model, hold power steady through the write, and confirm all boards are detected before you walk away. Full walkthrough and recovery steps: Avalon firmware update guide.
