Introduction

BPI-M2M

Overview: BPI-M2M ubuntu linux
  Banana Pi M2M is another ARM SoC powered development board that offers great computing performance in an ultra portable form factor. It is a 51mm square with Allwinner A33 Quad-core A7 SoC and 512MB DDR3 RAM. 

Key Features

  • Quad Core ARM Cortex A7 CPU. R16
  • 512MB DDR3 SDRAM
  • WiFi (AP6212) & Bluetooth onboard

Development

Linux

Prepare

1. Prepare 8G/above TF card, USB-Serial interface.
2. Connect USB-Serial to 40 pin header uart2 for kernel console debug, 3 pin header uart0 beside usb port is not debug uart for bpi release images.

3. Install bpi-tools on your Linux PC, If you can't access this URL or any other problems, please go to bpi-tools repo and download this tools manually.
 $ apt-get install pv
 $ curl -sL https://github.com/BPI-SINOVOIP/bpi-tools/raw/master/bpi-tools | sudo -E bash
4. Download latest linux image, and confirm that the md5 checksum is correct.
5. Defautl login: pi/bananapi or root/bananapi.

Install Image to SDcard

1. Install image with bpi-tools on Linux, plug your sd card to your Linux PC
   $ sudo bpi-copy  xxx.img /dev/sdX
2. Install image with dd command on Linux, umount SDcard device /dev/sdX partitions if mounted automatically, Actually bpi-copy is the same as this dd command.
   $ sudo apt-get install pv
   $ sudo unzip -p xxx-bpi-m2m-xxx.img.zip | pv | dd of=/dev/sdX bs=10M status=noxfer
3. Install bpi image with Etcher 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 SDcard Linux image flashed and bootup the board with this SDcard.
2. Copy emmc image to udisk, plugin the udisk to board and mount it.
3. Install with bpi-tools command
   $ sudo bpi-copy xxx-bpi-m2m-xxx.img.zip /dev/mmcblk1
Note: If the emmc was flashed android image before, you must erase the boot partition of android before download linux image
   $ 
4. Or Install with dd command, umount mmcblk1p1 and mmcblk1p2 partition if mounted automatically, Actually bpi-copy is the same as this dd command
   $ sudo apt-get install pv
   $ sudo unzip -p xxxb-bpi-m2m-xxx.img.zip | pv | dd of=/dev/mmcblk1 bs=10M status=noxfer
5. After flash complete, power off safely and eject the sdcard.

Build Source Code

1. Get the bsp source code
 $ git clone https://github.com/BPI-SINOVOIP/BPI-M2M-bsp
2. Build the bsp source code
Please read the source code README.md

Advance Development

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

 $ sudo su
 # killall wpa_supplicant
 # wpa_passphrase <ssid> <passphrase> > /etc/wpa_supplicant/wpa_supplicant.conf              
 # ifconfig wlan0 up
 # iwlist wlan0 scan
 # wpa_supplicant -B -iwlan0 -c/etc/wpa_supplicant/wpa_supplicant.conf
 # dhclient eth0

There are some other command line ways, please google for them.

2. Use UI interface to setup WiFi Client

StartX

  • apt-get install xorg
  • apt-get install xserver-xorg
  • apt-get install xinit

NAS Application

1. Usb hub + sata to usb

  • HDD is supported

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"

WringPi 1602 LCD m2m.png

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
