Development

Let's get start to develop on BPI-M2U, 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 M2P

Load your first image on M2U

 1.You could download latest image from our forum
 * Here is an example image link: http://forum.banana-pi.org/t/banana-pi-bpi-m2u-berry-new-image-release-raspbian-jessie-8-0-2018-5-24/5812 
 
 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 M2U, and press power button setup M2U

Load your first image on M2U EMMC

 * Run your M2U with TF card
 * Copy "xxx-sd-emmc-xxx.img.zip / xxx-sd-emmc-xxx.img" to your USB disk
 * Plug your USB disk in M2U
 * After M2U 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 M2U, take TF card out, power on M2U

Advanced Development

How to build uboot & kernel

Install tools

Clone code

SATA

1. Mount SATA on M2U

Error creating thumbnail: Unable to save thumbnail to destination
  • After insert sata interface, execute "fdisk -l"
Error creating thumbnail: Unable to save thumbnail to destination
  • 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
Error creating thumbnail: Unable to save thumbnail to destination

OTG

1. On M2U console:

  • Execute "./adbd.sh", then execute "ps -ax | grep adbd" to see if adbd is set up
Error creating thumbnail: Unable to save thumbnail to destination

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"
Error creating thumbnail: Unable to save thumbnail to destination

Touch screen

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"
Error creating thumbnail: Unable to save thumbnail to destination

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:
Error creating thumbnail: Unable to save thumbnail to destination

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 -B -dd -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf
  • dhclient wlan0

2. Use UI interface to setup WiFi Client

Clear boot

Camara function

We use HDF5640 camara.

Error creating thumbnail: Unable to save thumbnail to destination

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

WringPi

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
Error creating thumbnail: Unable to save thumbnail to destination
  • 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
