Getting Started with M2 Zero
Introduction
BPI-M2 Zero
Banana Pi M2 Zero is an ultra compact single board computer measures only 60mm*30mm. It uses quad-core Cortex A7 allwinner H2+ processor, with 512MB RAM memory. It's ideal for light-weight systems with some space-limited applications. Like other members of Banana Pi, it supports both linux and android operating system.

Advanced Development
How to create an image
- Prepare a SD card which have installed system(Ubuntu/Raspbian/..)
- Boot your SD card with M2 Zero, after M2 Zero finish starting, copy your files and config your system, then poweroff M2 Zero. [If you don't want to config your system, you can skip this step]
- Plug your SD card in PC(which is running Linux), "cd /media", then "ln -s <your account> pi"
- Execute "bpi-migrate -c bpi-m2z.conf -c ubuntu-mate-from-sd.conf -d /dev/sdx"
- Then you could get your own image now
OTG
1. On M2 Zero 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 M2 Zero and PC(with Ubuntu system)
- Execute "adb devices" to see if PC has recognised M2 ZeroP OTG
- If yes, we could execute "adb shell" to connect M2 Zero by adb now
USB Ethernet
- Prepare a USB to OTG wire, usb ethernet adapter
- Use iperf3 to test network
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 -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" to test picture taking function
- "./cameratest.sh" to test video recording function
IR function
- Execute "getevent"
- Use your IR device to send information to M2 Zero
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"
