  香蕉派 BPI-M2 Berry 搭载4核 AllWinner V40处理器, 板载 1Gb内存和 8GbEmmc, 另外还搭载了WiFi和蓝牙模块, 接口方面, BPI-M2 Ultra 具备 2口USB 2.0, 1口 USB Otg, 1口HDMI, SATA 和 音频接口等. 

关键特性

  • Quad Core ARM Cortex A7 CPU V40.
  • 1GB DDR3 SDRAM.
  • WiFi (AP6212) & Bluetooth onboard.
  • SATA Interface

Development

Let's get start to develop on BPI-M2U, see amazing things happen.

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 M2P

Load your first image on M2U

 1.You could download latest image from our forum
 * Here is an example image link: http://forum.banana-pi.org/t/banana-pi-bpi-m2u-berry-new-image-release-raspbian-jessie-8-0-2018-5-24/5812 
 
 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 M2U, and press power button setup M2U

Load your first image on M2U EMMC

 * Run your M2U with TF card
 * Copy "xxx-sd-emmc-xxx.img.zip / xxx-sd-emmc-xxx.img" to your USB disk
 * Plug your USB disk in M2U
 * After M2U recognise USB disk, execute "bpi-copy xxx-sd-emmc-xxx.img.zip / xxx-sd-emmc-xxx.img" to install image on EMMC
 * Then power off M2U, take TF card out, power on M2U

Advanced Development

How to build uboot & kernel

Install tools

Clone code

SATA

1. Mount SATA on M2U

 M2U Sata.png
  • After insert sata interface, execute "fdisk -l"
 M2U Sata fdisk l.png
  • Then "mount /dev/sdx /mnt/xxx"

2. If you meet some errors when you mount SATA, try these following commands:

  • "fdisk /dev/sdx" to create new partition , set your partition numbers and size, after created partitions, input "wq" to save and quit.
  • "mkfs.ext2 /dev/sdx" to format the SATA
  • "mount /dev/sdx /mnt/xxx"

3. After you success to insert SATA, we could input following commands to test SATA interface:

  • "time dd if=/dev/xxx of=/dev/null bs=1M count=1000" to test read speed
  • "time dd if=/dev/zero of=/dev/sdx bs=1M count=1000" to test write speed

OTG

1. On M2U console:

  • Execute "./adbd.sh", then execute "ps -ax | grep adbd" to see if adbd is set up
 M2P ADBD.png

2. On PC terminal:

  • If adbd was succeed to set up, insert OTG-USB interface to M2U and PC(with Ubuntu system)
  • Execute "adb devices" to see if PC has recognised M2U OTG
  • If yes, we could execute "adb shell" to connect M2U by adb now

LCD 5" & LCD 7"

  • Execute "bpi-bootsel", you'll see a list of boot files
  • Find "BPI_M2U_LCD7.img.gz"
  • Then execute "bpi-bootsel /usr/lib/u-boot/bananapi/bpi-m2u/BPI_M2U_LCD7.img.gz"
 M2U bootsel lcd7.png

Touch screen

GMAC

Use iperf3 to test gmac

1. On PC Terminal:

  • Execute "iperf3 -s"

2. On M2U console:

  • TCP test: "iperf3 -c serverIP"
  • UDP test: "iperf3 -u -c serverIP"

M2U Gmac test.png

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 on M2U

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

IR function

  • Execute "getevent"
  • Use your IR device to send information to M2U

WringPi

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"

File System

  • read only system change to read & write mode: "mount -o remount,rw /"

Install Qt5.7 & Qtcreator

1.Prepare a 32Gb TF card

2.Use GParted to resize root point '/' as 32Gb

3.apt-get install libxcb*

4.download qt5.7

5.make & make install

6.apt-get install qtcreator

7.Config qtcreator
