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-bpi-m2m-xxx.img.zip /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

1. Prepare a SDcard with 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

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.

Note: If the emmc was flashed android image before, you must erase the boot partition of android before step 3 or step 4.

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

https://askubuntu.com/questions/518454/what-does-startx-command-do

NAS Application

1. Usb hub + sata to usb

• HDD is supported

• SSD 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

• Execute "curl -sL https://github.com/BPI-SINOVOIP/bpi-tools/raw/master/bpi-tools | sudo -E bash - "

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
