Development

Basic Development

Prepare

Prepare 8G/above TF card, USB-Serial interface, PC with Ubuntu System, connect USB-Serial Connect debug console to M2M 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

Install bpi image to SD card

1. Download image

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 W2, 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 M4, eject the sdcard and poweron with emmc boot.

Build Source Code

Get the bsp source code

Build & Install

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

• 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

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
