Development For Android

Load your first image on M2P

 * Download PhoenixCard: https://pan.baidu.com/s/1-fjvPqtG_zewVzqnXf1AHw?pwd=eid9

 1.You could download latest image from our forum.
 Ex: http://forum.banana-pi.org/t/bananapi-bpi-m2p-h3-new-image-android7-0-release-2018-6-30/6147
 
 2.Put your TF card into a TF-USB adapter, and then plug adapter in your Windows PC usb interface.
 
 3.Prepare your image, and download image burning tools PhoenixCard.exe.
 
 4.Use "PhoenixCard.exe" to burn android image to TF card.

 * Here is the example of M3
 

Error creating thumbnail: Unable to save thumbnail to destination

Load your image on M2P EMMC

 1.The only different with sd card burning is the image burning mode item choice

 * Here is the example of M3
 

Error creating thumbnail: Unable to save thumbnail to destination

 2.After succeed to burn image to SD, then plug SD card in your M2P
 
 3.Press power button, device will copy image to EMMC automatically

 * Download PhoenixCard: https://pan.baidu.com/s/1-fjvPqtG_zewVzqnXf1AHw?pwd=eid9

Development For Linux

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 M2P

 1.You could download latest image from our forum
 * Here is the example forum thread link: http://forum.banana-pi.org/t/banana-pi-bpi-m2p-new-image-release-ubuntu-16-04-v1-1/5719
 
 2.Install bpi-tools on your Ubuntu. If you can't access this URL or any other problems, please go to bpi-tools repo and install this tools manually.
 * 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 M2P, and press power button setup M2P.
 
 5.Login user/password: pi/bananapi or root/bananapi.

Load your first image on M2P EMMC

 * Run your M2P with TF card
 * Copy "xxx-sd-emmc-xxx.img.zip / xxx-sd-emmc-xxx.img" to your USB disk
 * Plug your USB disk in M2P
 * After M2P 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 M2P, take TF card out, power on M2P with EMMC

Update your image

For example, update your image to support new emmc5.1

  * execute “bpi-tools”, to update your bpi tools;
  * execute “bpi-update -c bpi-m2p.conf”, to download new driver to update your image
  * execute “file *.tgz”, to check download files’ type is compressed data
  * execute “bpi-bootsel”, you will see the bootloader path, “/usr/lib/u-boot/bananapi/bpi-m2p/BPI_M2P_720P.img.gz”
  * execute “bpi-bootsel /usr/lib/u-boot/bananapi/bpi-m2p/BPI_M2P_720P.img.gz”, to update your bootloader
  * reboot

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://github.com/BPI-SINOVOIP/bpi-tools/raw/master/bpi-tools | sudo -E bash

Clone code

• git clone: https://github.com/BPI-SINOVOIP/BPI-M2P-bsp.git
• ./build.sh

How to create an image

• Prepare a SD card which have installed system(Ubuntu/Raspbian/..)
• Boot your SD card with M2P, after M2P finish starting, copy your files and config your system, then poweroff M2P. [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-m2p.conf -c ubuntu-mate-from-sd.conf -d /dev/sdx"
• Then you could get your own image now

GPIO Control

• To access a GPIO pin you first need to export it with

 echo XX > /sys/class/gpio/export

• with XX being the number of the desired pin. To obtain the correct number you have to calculate it from the pin name (like PH18)

 (position of letter in alphabet - 1) * 32 + pin number
  for PH18 this would be ( 8 - 1) * 32 + 18 = 224 + 18 = 242 (since 'h' is the 8th letter)

• echo "out/in" > /sys/class/gpio/gpio*NUMBER*/direction
• echo "0/1" > /sys/class/gpio/gpio*NUMBER*/value

OTG

1. On M2P 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 M2P and PC(with Ubuntu system)
• Execute "adb devices" to see if PC has recognised M2P OTG
• If yes, we could execute "adb shell" to connect M2P by adb now

GMAC

• Use iperf3 to test gmac

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 M2P

Driver code:

• https://github.com/BPI-SINOVOIP/BPI_WiFi_Firmware

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

Change Logo

1.Download M2P bsp code

• Execute command “git clone https://github.com/BPI-SINOVOIP/BPI-M2P-bsp”

• After you cloned project, execute command “cd BPI-M2P-bsp”

2.Change to your boot logo

• Prepare a ".bmp" picture, here I rotate 180°, as follows :

Error creating thumbnail: Unable to save thumbnail to destination

• Change your picture name as "bootlogo.bmp"
• put your picture to "sunxi-pack/chips/sun8iw7p1/configs/BPI-M2P-xxxP/"

Here I replaced “bootlogo.bmp” which is under “sunxi-pack/chips/sun8iw7p1/configs/BPI-M2P-720P/” as an example：

Error creating thumbnail: Unable to save thumbnail to destination

3.Build your code

• "./build.sh BPI-M2P-720P"
• choose 1

Error creating thumbnail: Unable to save thumbnail to destination

• After you built the project, you will see “SD” directory

4.Install a raspbian image on your SD card

5.Plug your SD card into your Ubuntu PC

(1) check your SD card was recognised as /dev/sdxx, as you can see, mine sd card was recognised as /dev/sde

Error creating thumbnail: Unable to save thumbnail to destination

6.Then “cd SD/bpi-m2p/100MB”

7.Execute command “bpi-bootsel BPI-M2P-720P.img.gz /dev/sde”

Error creating thumbnail: Unable to save thumbnail to destination

8.Insert your updated SD card to board, and power on, you will see:

Clear boot

• git clone https://github.com/BPI-SINOVOIP/BPI-files/tree/master/SD/100MB
• bpi-bootsel BPI-cleanboot-8k.img.gz /dev/sdX
