BPI-M2 Zero

香蕉派 M2 Zero 是一种超小型单板电脑,量度仅为60mm×30mm, 其搭载了4核 Cortex A7架构的 allwinner芯片 H2+, 外加512Mb内存. 其适用于空间有限的轻量级系统, 像香蕉派的其他开发板一样,它支持Linux和Android操作系统。

关键特性

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

Development

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

Load your first image on M2 Zero

 1.You could download latest image from our forum
 * Here is the example: http://forum.banana-pi.org/t/bananapi-bpi-m2z-h2-new-image-raspbian-ubuntu-release-2018-07-09/6221
 
 2.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
 
 3.After you download the image, insert your TF card into your Ubuntu
 * Execute "bpi-copy xxx.img /dev/sdx" to install image on your TF card.
 
 4.After step 3, then you can insert your TF card into M2 Zero, and press power button setup M2 Zero

Update your image

 1.Clone M2Z repo: https://github.com/BPI-SINOVOIP/BPI-M2Z-bsp
 * git clone https://github.com/BPI-SINOVOIP/BPI-M2Z-bsp
 2.Build your project
 * ./build.sh BPI-M2Z-720P
 3.After finish built, Execute "cd SD", plug your Ubuntu TFcard in PC, then check your TFcard was recognised as /dev/sdX by Ubuntu. 

 4. Execute "bpi-update -c bpi-r2.conf -d /dev/sdX", to update the compiled kernel to your TFcard

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

OTG

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

Bluetooth

  • 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
  • network={ ssid="ssid" psk="password" priority=1 }
  • wpa_supplicant -B -dd -i wlan0 -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.

Guvcview

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

Shell

  • 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

BPI-Tools

Install Bpi-tools

Update Bpi-tools

  • Execute "bpi-tools"

RPi.GPIO

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

WiringPi

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"

8x8 RGB LED Martix

  • Firstly you need a GPIO Extend Board for 8x8 LED Martix

WringPi LED Martix Extend Board.png

  • Execute "/usr/local/bin/bpi_test_gpio40.sh"
