Deploy on LicheeRV Nano

This document walks you through deploying PicoClaw on the Sipeed LicheeRV Nano development board.

LicheeRV Nano is an ultra-compact development board (only 22.86 × 35.56 mm) powered by the Sophgo SG2002 processor (featuring a 1 GHz selectable RISC-V/ARM main core and a 700 MHz RISC-V secondary core). It includes 256 MB DDR3 memory and an NPU with 1 TOPS of computing power. The board also provides rich interfaces, including MIPI-CSI, MIPI-DSI, SDIO, ETH, USB, SPI, UART, and I2C, making it suitable for a wide range of expansion scenarios. Its pin-header and castellated-hole compatible design also makes later mass-production SMT integration easier.

Prerequisites​

  • System and network: Your LicheeRV Nano should already be flashed and connected to the network. We recommend using the official Sipeed system image. You can write the image to an SD card using tools such as Win32DiskImager or balenaEtcher.

  • SSH access: Make sure you can access the device remotely via SSH.

Deploy via SSH​

Make sure your host machine and the LicheeRV Nano are on the same LAN, then connect to the board via SSH. You can install PicoClaw using either of the following methods:

Use curl to download and run the install_picoclaw.py script in one step:

curl -o install_picoclaw.py https://raw.githubusercontent.com/sipeed/picoclaw_docs/main/static/scripts/maixcam/install_picoclaw.py && python3 install_picoclaw.py

Method 2: Manual download and setup​

If you prefer a manual setup, run the following commands in sequence:

curl -L# -o picoclaw_Linux_riscv64.tar.gz \
https://picoclaw-downloads.tos-cn-beijing.volces.com/latest/picoclaw_Linux_riscv64.tar.gz

mkdir -p /root/picoclaw
gzip -dc picoclaw_Linux_riscv64.tar.gz | tar -xvf - -C /root/picoclaw

cp /root/picoclaw/picoclaw* /usr/bin

rm -rf /root/picoclaw /root/picoclaw_Linux_riscv64.tar.gz

Start the TUI​

After installation, run the following command to open PicoClaw's TUI (terminal user interface) for configuration and management:

picoclaw-launcher-tui

Start the Web UI​

If you prefer a graphical interface, run the following command in the terminal to start the web service:

picoclaw-launcher -no-browser -public

After the service starts, open a browser on a device in the same LAN and visit:

http://<device-ip>:18800

Tip: Replace <device-ip> with the actual LAN IP address assigned to your LicheeRV Nano.
