Flash Firmware

NMMiner ships as a single browser-flashable image. No esptool or idf.py required.

  1. Open flash.nmminer.com in Chrome or Edge. Firefox / Safari do not implement WebSerial.
  2. Plug your board in via USB.
  3. Pick your board from the list. The tool will fetch the matching firmware from the official GitHub release.
  4. Click Install, choose the serial port, and wait for "Flash complete".
  5. The tool will prompt you to purchase a licence. Once purchased, it displays your licence string — copy it. You will need it once on the activation page.
warning

If your board does not auto-enter download mode, hold BOOT while pressing RESET, then release.
