• 2GB DDR3 SDRAM
• 8 GB eMMC storage
• WiFi (AP6212) & Bluetooth onboard
• SATA Interface

Development

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

Basic Development

Prepare to develop

 1.Prepare 8G/above TF card, USB-Serial interface, PC with Ubuntu System

 2.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 the example forum thread link: 

 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.

Advanced Development

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 , after created 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 "./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.

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 -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 camara.

Guvcview

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

• We also have built-in command in /usr/local/bin to test camara
• test_ov5640_image_mode.sh
• cameratest.sh

IR function

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

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 bpi_test_lcd1602

0.96 Inch OLED Display

• Execute bpi_test_52pi

8x8 RGB LED Martix

• Firstly you need a GPIO Extend Board for 8x8 LED Martix

• Execute bpi_test_gpio40
