toome123 / 8iaxe

Miner with 8 Asic-chips based on the 0xaxe

8]axe

The 8]axe is a 8-ASIC-BM1366 Miner based on the 0xaxe

rev1: averaging at about 3.3-3,6TH/s with ~90 Watts on the wall on default settings (485Mhz)

note: The 8]axe is not a stand-alone device because it only supports USB. It can be run connected to a Raspberry Pi without problems. Also multiple devices can be connected to a single Pi.

ASICs

The 8]axe uses 8 ASICs of type BM1366

Compilation (Bootloader or CMSIS-DAP)

Start WSL on your PC and go through the followig steps:

# install curl
sudo apt install curl

# install rust
curl --proto '=https' --tlsv1.2 https://sh.rustup.rs -sSf | sh

# add to ~/.bash.rc (afterwards, opening a new terminal is needed)
echo 'source "$HOME/.cargo/env"' >> ~/.bashrc

# clone repository
git clone https://github.com/shufps/0xaxe

# clone submodules
cd 0xaxe
git submodule init
git submodule update

# add rust target for STM32L0 variants
rustup target add thumbv6m-none-eabi

# build firmware for L072
cd firmware/fw-L072KZ
./build.sh

Using it on Windows running WSL

For windows the usbipd is needed to connect the device to WSL. Install it from here:

https://github.com/dorssel/usbipd-win/releases

Afterwards reboot your PC and open the cmd as Administrator.

Connect the USB to your PC and power on the 12V while pressing the BOOT Button to start the device in BOOT-Mode

Then:

C:\Windows\System32>usbipd list
Connected:
BUSID  VID:PID    DEVICE                                                        STATE

4-2    2e8a:000c  Picoprobe CMSIS-DAP v2, Serielles USB-Gerät (COM3)            Attached

Note the BUSID for the STM32. Then

C:\Windows\System32> usbipd bind --busid 4-2

Afterwards start your WSL Linux

Then attach the device with:

C:\Windows\System32> usbipd attach --wsl --busid 4-2

When it is running you can check in your WSL-Linux if the probe is detected:

probe-rs list

The following debug probes were found:
[0]: Picoprobe CMSIS-DAP (VID: 2e8a, PID: 000c, Serial: E66138528337A532, CmsisDap)

Installation via USB Bootloader on board with BOOT button

The STM32L072CB variant has an integrated DFU Bootloader that starts when pressing the BOOT button during reset.

Afterwards the firmware can be flashed via dfu-utils:

# install cargo-binutils and llvm tools
cargo install cargo-binutils
rustup component add llvm-tools-preview

# create the firmware.bin
DEFMT_LOG=info cargo objcopy --release --bin qaxe -- -O binary 0xaxe.bin

# install dfu-utils
sudo apt-get install dfu-util

# after booting, list the devices
dfu-util --list

# flash the binary
dfu-util -a 0 -s 0x08000000:leave -D 0xaxe.bin

Config

Use the "config.yml.example" of the Piaxe-Miner and change it as follows:

debug_bm1366: false
verify_solo: false
miner: 0xaxe

# works only with public pool
#suggest_difficulty: 2048

0xaxe:
  name: 8]axe
  chips: 8
  fan_speed_1: 0.8
  asic_frequency: 480
  extranonce2_interval: 1.5
  serial_port_asic: "/dev/ttyACM0"
  serial_port_ctrl: "/dev/ttyACM1"
