Development

Let's get start to develop on BPI-M2U, see amazing things happen.

Basic Development

Linux

 * Prepare 8G/above TF card, USB-Serial interface, PC with Windows System
 * Using your USB-Serial Connect debug console on M2P

 1.You could download the latest image from our wiki.
 * BPI-M2U: https://wiki.banana-pi.org/Banana_Pi_BPI-M2U#Image_Release
 * BPI-M2 Berry: https://wiki.banana-pi.org/Banana_Pi_BPI-M2_Berry#Image_Release
   
 2.Put the TF card into a TF-USB adapter and plug it to your PC USB interface.
 
 3.Download the flashing tools "BalenaEtcher" and start it.
 
 4.Click "Flash from file" to select your image file.(.img or .zip)
 
 5.Click "Select target" to choose your USB device.
 
 6.Start to flash and wait for burning completely.
 
 

Android

 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.
 
 

 * Download PhoenixCard: https://pan.baidu.com/s/1-fjvPqtG_zewVzqnXf1AHw?pwd=eid9

Load your first image on M2U EMMC

 1.Bootup your M2U with Micro SD card
 2.Copy "xxx-sd-emmc-xxx.img.zip / xxx-sd-emmc-xxx.img" to your USB disk
 3.Plug your USB disk in M2U
 4.Mount the USB disk and flash the image file to eMMC

 * bpi-tools
 curl -sL https://github.com/BPI-SINOVOIP/bpi-tools/raw/master/bpi-tools%7Csudo -E bash
 mount /dev/sda1 /mnt
 cd /mnt
 bpi-copy xxx-sd-emmc-xxx.img.zip /dev/mmcblk0

 * dd command
 mount /dev/sda1 /mnt
 cd /mnt
 unzip -p xxx-sd-emmc-xxx.img.zip |pv| dd of=/dev/mmcblk0 bs=10M status=noxfer

 5.Then power off M2U, take TF card out, power on M2U

Advanced Development

How to build uboot & kernel

Install tools

• apt-get udpate
• apt-get install gcc-arm-linux-gnueabihf u-boot-tools
• apt-get install pv
• curl -sL https://github.com/BPI-SINOVOIP/bpi-tools/raw/master/bpi-tools | sudo -E bash

Clone code

• git clone: https://github.com/BPI-SINOVOIP/BPI-M2U-bsp.git
• ./build.sh

SATA

1. Mount SATA on M2U

• 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 M2U console:

• Execute "/usr/local/bin/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 M2U and PC(with Ubuntu system)
• Execute "adb devices" to see if PC has recognised M2U OTG
• If yes, we could execute "adb shell" to connect M2U by adb now

LCD 5" & LCD 7"

• Execute "bpi-bootsel", you'll see a list of boot files
• Find "BPI_M2U_LCD7.img.gz"
• Then execute "bpi-bootsel /usr/lib/u-boot/bananapi/bpi-m2u/BPI_M2U_LCD7.img.gz"

GMAC

Use iperf3 to test gmac

1. On PC Terminal:

• Execute "iperf3 -s"

2. On M2U 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 M2U

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

IR function

• Execute "getevent"
• Use your IR device to send information to M2U

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

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 /"

Install Qt5.7 & Qtcreator

1.Prepare a 32Gb TF card

2.Use GParted to resize root point '/' as 32Gb

3.apt-get install libxcb*

4.download qt5.7

5.make & make install

6.apt-get install qtcreator
