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

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 M2M

Install Bpi tools

Load your first Linux image on SD card

  • Ex: my sd card is recognised as /dev/sdf
  • I can use "bpi-copy xxx.img /dev/sdf" to install image on my SD card.

Compile code

After download code, execute "./build.sh" to compile it.

  • ./build.sh

Update your image

Update rootfs & kernel

After we succeed to the code, Bootloader, kernel, rootfs will be generated in "SD" directory, then how to update the image?

  • cd SD/bpi-m2m

M2m code sd.png

Plug in your SD card to Ubuntu PC, then execute "fdisk -l" to check which /dev/sdX were generated by system

  • bpi-update -c bpi-m2m.conf -d /dev/sde

Update boot

  • cd 100MB

Execute "df -l" to check which /dev/sdX is "BPI-BOOT"

  • df -l

M2m df l.png

  • bpi-bootsel BPI-M2M-LCD7-8k.img.gz /dev/sd1

Make your own image

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 -iwlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf
  • dhclient wlan0

2. Use UI interface to setup WiFi Client

NAS Application

1. Usb hub + sata to usb

  • HDD is supported

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
