Development

Let's get start to develop on BPI-M3, see amazing things happen.

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 M3

Load your first image on M3

 1.You could download latest image from our forum
 
 2.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
 
 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 M3, and press power button setup M3

Load your first image on M3 EMMC

 * Run your M3 with TF card
 * Copy "xxx-sd-emmc-xxx.img.zip / xxx-sd-emmc-xxx.img" to your USB disk
 * Plug your USB disk in M3
 * After M3 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 M3, take TF card out, power on M3

How to buld M3 Bsp code

 * Prepare a PC which runs ubuntu
 * Install Docker-ce on your PC，https://docs.docker.com/install/linux/docker-ce/ubuntu/#install-docker-ce
 * After install Docker, execute "docker pull sinovoip/bpi-build:ubuntu12.04", to pull image
 * Then you pulled image, execute "docker run -t -i sinovoip/bpi-build:ubuntu12.04 /bin/bash" to start a bash
 * Execute "git clone https://github.com/BPI-SINOVOIP/BPI-M3-bsp.git" on your ubuntu terminal
 * Execute "./build.sh" to build M3 bsp code
 * After built, open a new terminal, execute "docker cp xxxxx(your container id):xxxxx(your project path) xxxxx(your pc path)"
 
 

Advanced Development

SATA

1. Mount SATA on M3

• After insert sata interface, execute "fdisk -l"
• Then "mount /dev/sdx /mnt/xxx"

2. If you meet some errors when you mount SATA, try these following commands:

• "fdisk /dev/sdx" to create new partition , set your partition numbers and size, after created partitions, input "wq" to save and quit.
• "mkfs.ext2 /dev/sdx" to format the SATA
• "mount /dev/sdx /mnt/xxx"

3. After you success to insert SATA, we could input following commands to test SATA interface:

• "time dd if=/dev/xxx of=/dev/null bs=1M count=1000" to test read speed
• "time dd if=/dev/zero of=/dev/sdx bs=1M count=1000" to test write speed

OTG

1. On M3 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 M3 and PC(with Ubuntu system)
• Execute "adb devices" to see if PC has recognised M3 OTG
• If yes, we could execute "adb shell" to connect M3 by adb now

LCD 5" & LCD 7"

• Execute "bpi-bootsel", you'll see a list of boot files
• Find "BPI_M3_LCD7.img.gz"
• Then execute "bpi-bootsel /usr/lib/u-boot/bananapi/bpi-M3/BPI_M3_LCD7.img.gz"

GMAC

Use iperf3 to test gmac

1. On PC Terminal:

• Execute "iperf3 -s"

2. On M3 console:

• TCP test: "iperf3 -c serverIP"
• UDP test: "iperf3 -u -c serverIP"

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 M3

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 -B -dd -i wlan0 -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(The left one) camara and HDF8865(The right one).

Guvcview

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

Shell

Ov5640

• 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

Ov8865

• "/test_ov8865.sh"

IR function

• Execute "getevent"
• Use your IR device to send information to M3

WringPi

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

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"

File System

• read only system change to read & write mode: "mount -o remount,rw /"
