Factory Setup

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

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

• 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

• recommended values for the Bitaxe 1397

3. 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

4. Flash the merged firmware and config.cvs onto your Bitaxe

bitaxetool --config ./config.cvs --firmware ./esp-miner-factory-v2.0.0.bin

Thank you to @benjamin-wilson, @skot, @Georges760, @developeralgo8888, @SatsForFreedom, and the Open Source Miners United (OSMU) community for their contributions to this release.

Firmware for the Bitaxe v2.2

• Supports Stratum v1
• 300-350 GH/s
• Wifi connectivity
• Mining statistics visible on OLED display
• Power management for solar applications

Instructions:

1. Copy config.cvs.example to config.cvs and modify myssid/mypass with your home Wifi credentials (Only supports 2.4ghz connection) and stratumurl/stratumport/stratumuser/stratumpass with the stratum server and login that you would like to use.

2. 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

3. Flash the firmware and config.cvs onto your Bitaxe

bitaxetool --config ./config.cvs --firmware ./esp-miner.bin

Note: esp-miner-475.bin uses bm1397 hashing frequency of 475 and esp-miner-425.bin is set to 425
