BPI-M2 Zero

Banana Pi M2 Zero is an ultra compact single board computer measures only 60mm*30mm. It uses quad-core Cortex A7 allwinner H2+ processor, with 512MB RAM memory. It's ideal for light-weight systems with some space-limited applications. Like other members of Banana Pi, it supports both linux and android operating system.

Key Features

  • Quad Core ARM Cortex A7 CPU H2+
  • 512MB SDRAM.
  • WiFi (AP6212) & Bluetooth onboard.
  • Mini HDMI.


Basic Development

Prepare to develop

 * Prepare 8G/above TF card, USB-Serial interface, PC with Ubuntu System
 * Using your USB-Serial Connect debug console on M2 Zero

Install Linux Image on M2 Zero

Download latest Linux image

Install Image to SDcard on Linux PC with bpi-tools

1. Install bpi-tools on your system
   $ apt-get install pv
   $ curl -sL https://github.com/BPI-SINOVOIP/bpi-tools/raw/master/bpi-tools | sudo -E bash
2. Insert your SDcard into your PC
   $ bpi-copy xxx.img /dev/sdx

Install Image to SDcard with Ether on Windows, Linux and MacOS

Balena Etcher is an open source project by Balena, Flash OS images to SD cards & USB drives

Install Image to EMMC with SD Ubuntu

1.Prepare a sd which is installed ubuntu image and bootup with sdcard
2.Copy emmc image to udisk, plug in board, then mount udisk.
3.After mount udisk, use command "bpi-copy xxx-emmc-xxx.img" to install image on Emmc.
4.After success install, power off the board, eject the sdcard and poweron with emmc boot.

Update your image

1. Get the m2 zero bsp source code
   $ git clone https://github.com/BPI-SINOVOIP/BPI-M2Z-bsp
2. Build the source code according to the README.md, and update the packages to the sdcard with bpi image flashed.

Advanced Development

How to create an image

  • Prepare a SD card which have installed system(Ubuntu/Raspbian/..)
  • Boot your SD card with M2 Zero, after M2 Zero finish starting, copy your files and config your system, then poweroff M2 Zero. [If you don't want to config your system, you can skip this step]
  • Plug your SD card in PC(which is running Linux), "cd /media", then "ln -s <your account> pi"
  • Execute "bpi-migrate -c bpi-m2z.conf -c ubuntu-mate-from-sd.conf -d /dev/sdx"
  • Then you could get your own image now


1. On M2 Zero console:

  • Execute "./adbd.sh", then execute "ps -ax | grep adbd" to see if adbd is set up

2. On PC terminal:

  • If adbd was succeed to set up, insert OTG-USB interface to M2 Zero and PC(with Ubuntu system)
  • Execute "adb devices" to see if PC has recognised M2 ZeroP OTG
  • If yes, we could execute "adb shell" to connect M2 Zero by adb now

USB Ethernet

  • Prepare a USB to OTG wire, usb ethernet adapter

  • Use iperf3 to test network

  • Use bluetoothctl tool to operate BT
  • Execute "bluetoothctl"
  • If you don't know how to use bluetoothctl, type "help", you will see more commands
  • Execute these commands:

WiFi Client

You have two ways to setup WiFi Client

1. Use commands to setup WiFi client

  • ip link set wlan0 up
  • iw dev wlan0 scan | grep SSID
  • vim /etc/wpasupplicant/wpa_supplicant.conf
  • wpa_supplicant -iwlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf
  • dhclient wlan0

2. Use UI interface to setup WiFi Client

Clear boot

Camara function

We use HDF5640 camara.

Ov5640 camara.png


  • Use your UI interface to operate camara
  • Applications -> Sound & Video -> guvcview


  • We also have built-in command in /usr/local/bin to test camara
  • "./test_ov5640_image_mode.sh" to test picture taking function
  • "./cameratest.sh" to test video recording function


How to change display resolution

For Example: we change M2Z HDMI display 1080P.

1. First, mount /dev/mmcblk0p1 /mnt, then enter to /mnt/bananapi/bpi-m2z/linux, find "sys_config.fex";

2. "vim sys_config.fex", change "screen0_output_mode = 5" to "screen0_output_mode = 10"

3. After save changed, use "fex2bin" command to transfer sys_config.fex to bin file, "fex2bin sys_config.fex script.bin ", reboot.

Install Bpi-tools

Update Bpi-tools

  • Execute "bpi-tools"



Install RPi.GPIO

  • Execute "git clone https://github.com/BPI-SINOVOIP/RPi.GPIO"
  • after clone the repo, cd RPi,GPIO
  • Execute "sudo apt-get update"
  • Execute "sudo apt-get install python-dev python3-dev"
  • Execute "sudo python setup.py install" or "sudo python3 setup.py install" to install the module

Using RPi.GPIO

  • cd /usr/local/bin
  • Execute "./bpi_test_g40.py" to test RPi.GPIO

How to Update WiringPi

  • Execute "bpi-update -c pkglist.conf"

Update Pkglist.png

  • Execute "bpi-update -c bpi-pkg-bpi-wiringpi.conf"

Update WringPi.png

RGB 1602 LCD

  • Execute "/usr/local/bin/bpi_test_lcd1602.sh"

0.96 Inch OLED Display

  • Execute "/usr/local/bin/bpi_test_52pi.sh"
