Development

Basic Development

Load your first Android image on M1

 1.You could download latest image from our forum.
 
 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.
 
 

Prepare to develop

 * Prepare 8G/above TF card, USB-Serial interface, PC with Ubuntu System
 * Using your USB-Serial Connect debug console on P2 Zero
 
 

Install Linux Image on P2 Zero

Download latest Linux image, default login user/password is pi/bananapi or root/bananapi.

Install Image to SDcard on Linux PC with bpi-tools

1. 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

If you can't access this URL or any other problems, please go to bpi-tools repo and install this tools manually.

2. Insert your SDcard into your PC

   $ bpi-copy xxx.img /dev/sdx
 

Install Image to SDcard with Ether 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 sd which is installed ubuntu image and bootup with sdcard

2.Copy emmc image to udisk, plug in board, then mount udisk.

3.After mount udisk, use command "bpi-copy xxx-emmc-xxx.img" to install image on Emmc.

4.After success install, power off the board, eject the sdcard and poweron with emmc boot.

Update your image

1. Get the p2 zero bsp source code

   $ git clone https://github.com/BPI-SINOVOIP/BPI-M2P-bsp-4.4

2. Build the source code according to the README.md, and update the packages to the sdcard with bpi image flashed.

Install Image to EMMC

1. Prepare a SDcard with Linux image flashed and bootup board with this SDcard.

2. Copy Linux image to udisk, plug the udisk to OTG Port(via USB-to-MicroUSB) of the board and mount it.

3. Install with dd command, umount mmcblk0p1 and mmcblk0p2 partition if mounted automatically. Actually bpi-copy is the same as this dd command.

 $ sudo apt-get install pv unzip
 $ sudo unzip -p xxx-bpi-p2zero-xxx.img.zip | pv | dd of=/dev/mmcblk0 bs=10M status=noxfer

4. Install the linux image in udisk with bpi-tools command

 $ sudo apt-get install pv unzip
 $ sudo bpi-copy xxx-bpi-p2zero-xxx.img.zip /dev/mmcblk0

5. After download complete, power off safely and eject the SDcard.

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

EMac

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

2. Use UI interface to setup WiFi Client

Clear boot

• git clone https://github.com/BPI-SINOVOIP/BPI-files/tree/master/SD/100MB
• bpi-bootsel BPI-cleanboot-8k.img.gz /dev/sdX

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

Display

How to change display resolution

For Example： we change M2Z HDMI display 1080P.

1. First, mount /dev/mmcblk0p1 /mnt, then enter to /mnt/bananapi/bpi-m2z/linux, find "sys_config.fex";

2. "vim sys_config.fex", change "screen0_output_mode = 5" to "screen0_output_mode = 10"

3. After save changed, use "fex2bin" command to transfer sys_config.fex to bin file, "fex2bin sys_config.fex script.bin ", reboot.
