Mraa on ROCK Pi boards

This document describes how to build and use mraa for ROCK Pi boards.

List of ROCK Pi Boards supported

  • ROCK Pi 4 A/B/C
  • ROCK Pi E
  • ROCK Pi N10
  • ROCK Pi S
  • ROCK Pi X

List of Linux Distributions

  • Ubuntu
  • Debian
  • Yocto (mraa-radxa_git.bb)

Install example: Install Mraa on ROCK Pi N10 Debian system

For Debian Distribution the below commands install the essential set:

root@rockpin10bc:/home/rock# apt-get install -y git build-essential swig3.0 python-dev  cmake libjson-c-dev libnode-dev
root@rockpin10bc:/home/rock# apt-get install -y libc6 libjson-c3 libgcc1 libstdc++6 python2.7 libpython2.7 python3.7 libpython3.7 python3-dev
root@rockpin10bc:/home/rock# apt-get install -y libgtest-dev pkg-config cmake-data

Get source code.

root@rockpin10bc:/home/rock# git clone -b master https://github.com/radxa/mraa.git
root@rockpin10bc:/home/rock# cd mraa

Patch the source code for building mraa with Python.
