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.

Key Features

Quad Core ARM Cortex A7 CPU H2+
512MB SDRAM.
WiFi (AP6212) & Bluetooth onboard.
Mini HDMI.

Development

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 M2 Zero

Load your first image on M2 Zero

 1.You could download latest image from our forum
 * Here is the example: http://forum.banana-pi.org/t/bananapi-bpi-m2z-h2-new-image-raspbian-ubuntu-release-2018-07-09/6221
 
 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 M2 Zero, and press power button setup M2 Zero

Update your image

 1.Clone M2Z repo: https://github.com/BPI-SINOVOIP/BPI-M2Z-bsp
 * git clone https://github.com/BPI-SINOVOIP/BPI-M2Z-bsp

 2.Build your project
 * ./build.sh BPI-M2Z-720P

 3.After finish built, Execute "cd SD", plug your Ubuntu TFcard in PC, then check your TFcard was recognised as /dev/sdX by Ubuntu. 

 4. Execute "bpi-update -c bpi-r2.conf -d /dev/sdX", to update the compiled kernel to your TFcard

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

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

BPI-Tools

Install Bpi-tools

Execute "curl -sL https://github.com/BPI-SINOVOIP/bpi-tools/raw/master/bpi-tools | sudo -E bash - "

Update Bpi-tools

Execute "bpi-tools"

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

WiringPi

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

How to Update WiringPi

Execute "bpi-update -c pkglist.conf"

Execute "bpi-update -c bpi-pkg-bpi-wiringpi.conf"

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"
