  • Quad-core 1.2GHz Cortex-A7 H3
  • 1GB DDR3
  • 8GB eMMC onboard
  • WiFi and BlueTooth onboard
  • 10/100/1000Mbps Ethernet Port

Development For Android

Load your first image on M2P

 1.You could download latest image from our forum.
 Ex: http://forum.banana-pi.org/t/bananapi-bpi-m2p-h3-new-image-android7-0-release-2018-6-30/6147
 
 2.Put your TF card into a TF-USB adapter, and then plug adapter in your Windows PC usb interface.
 
 3.Prepare your image, and download image burning tools PhoenixCard.exe.
 
 4.Use "PhoenixCard.exe" to burn android image to TF card.
 * Here is the example of M3

Load your image on M2P EMMC

 1.The only different with sd card burning is the image burning mode item choice
 * Here is the example of M3

 2.After succeed to burn image to SD, then plug SD card in your M2P
 
 3.Press power button, device will copy image to EMMC automatically
 * Download PhoenixCard: https://pan.baidu.com/s/18Fo_JhYY02gmxtFw2Ps3rQ

Development For Linux

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 M2P

 1.You could download latest image from our forum
 * Here is the example forum thread link: http://forum.banana-pi.org/t/banana-pi-bpi-m2p-new-image-release-ubuntu-16-04-v1-1/5719
 
 2.Install bpi-tools on your Ubuntu
 * 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 M2P, and press power button setup M2P.

Load your first image on M2P EMMC

 * Run your M2P with TF card
 * Copy "xxx-sd-emmc-xxx.img.zip / xxx-sd-emmc-xxx.img" to your USB disk
 * Plug your USB disk in M2P
 * After M2P 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 M2P, take TF card out, power on M2P with EMMC

Update your image

For example, update your image to support new emmc5.1

  * execute “bpi-tools”, to update your bpi tools;
  * execute “bpi-update -c bpi-m2p.conf”, to download new driver to update your image
  * execute “file *.tgz”, to check download files’ type is compressed data
  * execute “bpi-bootsel”, you will see the bootloader path, “/usr/lib/u-boot/bananapi/bpi-m2p/BPI_M2P_720P.img.gz”
  * execute “bpi-bootsel /usr/lib/u-boot/bananapi/bpi-m2p/BPI_M2P_720P.img.gz”, to update your bootloader
  * reboot

Advanced Development

How to build uboot & kernel

Install tools

Clone code

How to create an image

  • Prepare a SD card which have installed system(Ubuntu/Raspbian/..)
  • Boot your SD card with M2P, after M2P finish starting, copy your files and config your system, then poweroff M2P. [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-m2p.conf -c ubuntu-mate-from-sd.conf -d /dev/sdx"
  • Then you could get your own image now

GPIO Control

  • To access a GPIO pin you first need to export it with
 echo XX > /sys/class/gpio/export
  • with XX being the number of the desired pin. To obtain the correct number you have to calculate it from the pin name (like PH18)
 (position of letter in alphabet - 1) * 32 + pin number
  for PH18 this would be ( 8 - 1) * 32 + 18 = 224 + 18 = 242 (since 'h' is the 8th letter)
  • echo "out/in" > /sys/class/gpio/gpio*NUMBER*/direction
  • echo "0/1" > /sys/class/gpio/gpio*NUMBER*/value

OTG

1. On M2P 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 M2P and PC(with Ubuntu system)
  • Execute "adb devices" to see if PC has recognised M2P OTG
  • If yes, we could execute "adb shell" to connect M2P by adb now

GMAC

  • Use iperf3 to test gmac

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 M2P

Driver code:

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

Clear boot

Camara function

We use HDF5640 camara.

Guvcview

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

Guvcview ov5640.png

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 M2P
