Hash Commander
Firmware

Hash Commander OS

Our own firmware for NerdQAxe++ and Bitaxe Gamma, based on open-source projects under the GPL license. A themed screen, a machine page built from scratch and installation through the app, with the signature verified before flashing.

What it is

A machine that is easier to keep an eye on

  • Machine screen with several themes, showing hashrate, pool, temperatures and Bitcoin.
  • Its own control page, with no dependence on AxeOS.
  • Integrates directly with the Hash Commander app.
  • Update files are signed and the app verifies the signature before installing.
Warning. Installing firmware and changing frequencies or voltages can damage your equipment. The risk is yours. Software provided without warranty.

Install

Two ways to install

  1. Through the app (recommended)

    In the app, open the Hash Commander OS tab, choose the machine and click install. The app downloads the firmware, verifies the signature and sends it over the local network (OTA).

  2. Over USB (advanced users)

    Download the factory file below and flash it to the machine over USB with an ESP32 flashing tool (for example esptool, at address 0x0). This erases the machine's current configuration.
