Firmware Update

Upgrading is the same as the first flash: re-open the browser flash tool, pick your board, install.

Steps​

  1. Open flash.nmminer.com in Chrome or Edge.
  2. Pick the board profile.
  3. Click Install, choose the serial port, wait for it to finish.

After updating you do not need to re-activate the licence. Settings (SSID / pool / wallet) survive the upgrade.

tip

A "new firmware available" banner is shown on the on-device loading page and miner page whenever a newer release is published.

Tracking firmware version remotely​

The current firmware version is reported by every miner via GET /api/system/info. Combine that with Swarm discovery and you can see at a glance which miners on the LAN still need an update.

What changes between versions​

See the GitHub release log for the full change log. Major version bumps (e.g. v1.x → v2.0) introduced breaking improvements to NM Monitor and Swarm — older releases are not interoperable with newer Swarm protocols, so it's best to keep your whole fleet on the same minor series.
