ESP-Miner-Nerdaxe version

Supported Targets	ESP32-S3
Old Platform	ESP-IDF v4.4.6
-----------------	---------------------
Required Platform	ESP-IDF v5.2.X
-----------------	---------------------

This is a forked version of ESP-miner, the original firmware of Bitaxe project developed by @skot/ESP-Miner, @ben and @jhonny. The current fork supports LVGL library with an UI that works with 8bit parallel screen over TTGO-TdiplayS3 board.

This features unfortunatelly can't be added to the original project because requires specific ESP-IDF version to be built.

Now firmware is up to date with current ESP-miner, so this firmware adds a Display layer

How to flash/update firmware

Online Flashtool [Recommended]

Easyiest way to flash firmware. Build your own miner using the folowing firwmare flash tool:

1. Get a TTGO T-display S3
2. Get a NerdAxe board
3. Go to flasher online tool: https://flasher.bitronics.store/ (recommend via Google Chrome incognito mode)

Bitaxetool

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-nerd101-v2.1.4.bin

How to build firmware

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

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 NerdAxe 1366 (ultra)

  key,type,encoding,value
  main,namespace,,
  asicfrequency,data,u16,485
  asicvoltage,data,u16,1200
  asicmodel,data,string,BM1366
  devicemodel,data,string,ultra
  boardversion,data,string,101
