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. If you can't access this URL or any other problems, please go to https://github.com/BPI-SINOVOIP/bpi-tools and install this tools manually.
 * apt-get install pv
 * curl -sL https://raw.githubusercontent.com/BPI-SINOVOIP/bpi-tools/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

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

Clone code

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

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"

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"
