ESP-Miner

Supported Targets	ESP32-S3 (BitAxe v2+)

Requires Python3.4 or later and pip

Install bitaxetool from pip. pip is included with Python 3.4 but if you need to install it check https://pip.pypa.io/en/stable/installation/

pip install --upgrade bitaxetool

Hardware Required

This firmware is designed to run on a BitAxe v2+

If you do have a Bitaxe with no USB connectivity make sure to establish a serial connection with either a JTAG ESP-Prog device or a USB-to-UART bridge

Preconfiguration

Starting with v2.0.0, the ESP-Miner firmware requires some basic manufacturing data to be flashed in the NVS partition.

1. Download the esp-miner-factory-v2.0.3.bin file from the release tab. Click here for the release tab

2. Copy config.cvs.example to config.cvs and modify asicfrequency, asicvoltage, asicmodel, devicemodel, and boardversion

The following are recommendations but it is necessary that you do have all values in your config.cvsfile to flash properly.

• recommended values for the Bitaxe 1366 (ultra)

  key,type,encoding,value
  main,namespace,,
  asicfrequency,data,u16,485
  asicvoltage,data,u16,1320
  asicmodel,data,string,BM1366
  devicemodel,data,string,ultra
  boardversion,data,string,0.11
  

• recomended values for the Bitaxe 1397 (MAX)

  key,type,encoding,value
  main,namespace,,
  asicfrequency,data,u16,475
  asicvoltage,data,u16,1400
  asicmodel,data,string,BM1397
  devicemodel,data,string,max
  boardversion,data,string,2.2
  

Flash

The bitaxetool includes all necessary library for flashing the binary file to the Bitaxe Hardware.

The bitaxetool requires a config.cvs preloaded file and the appropiate firmware.bin file in it's executed directory.

3. Flash with the bitaxetool

bitaxetool --config ./config.cvs --firmware ./esp-miner-factory-v2.0.3.bin
