Development

Basic Development

Prepare

Prepare 8G/above TF card, USB-Serial interface, PC with Ubuntu System, connect USB-Serial to 40 pin header uart2 for kernel console debug, 3 pin header uart0 beside usb port is not debug uart.

Install bpi-tools

 $ 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.

Install bpi image to SD card

1. Download latest linux image, defautl user/password is pi/bananapi or root/bananapi.

2. Install image with bpi-tools on Linux

plug your sd card to your Linux PC

       $ bpi-copy  xxx.img /dev/sdX

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 with SD Ubuntu

1. Prepare a sd which is installed ubuntu image and bootup with sdcard

2. Copy emmc image to udisk then plug in M2M, 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 M2M, eject the sdcard and poweron with emmc boot.

Build Source Code

Get the bsp source code

 $ git clone https://github.com/BPI-SINOVOIP/BPI-M2M-bsp

Build the bsp source code

 $ ./build.sh 1

Get the docker image from Sinovoip Dock Hub, build the source code with this docker image if you have build environment issue.

Install the bsp package to SD card with bpi image flashed

 $ sudo ./update_bsp2sd.sh /dev/sdX

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

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

WiringPi

• GitHub: https://github.com/BPI-SINOVOIP/BPI-WiringPi2.git
• We also have built-in test command in "/usr/local/bin"

How to Update WiringPi

• Execute "bpi-update -c pkglist.conf"

• Execute "bpi-update -c bpi-pkg-bpi-wiringpi.conf"

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

• Execute "/usr/local/bin/bpi_test_gpio40.sh"
