¶ Prepare
Download PhoenixCard: https://pan.baidu.com/s/1-fjvPqtG_zewVzqnXf1AHw?pwd=eid9
¶ Install Image to SD cards
-
Put your TF card into a TF-USB adapter, and then plug adapter in your Windows PC usb interface.
-
Prepare your image, and download image burning tools PhoenixCard.exe.
-
Use "PhoenixCard.exe" to burn android image to TF card.
-
Select the image in the image path option
-
Select set as card startup, then click on burn image
-
Burning ended，
-
¶ Linux
¶ Prepare
-
It’s recommended to use A1 rated cards, 8GB at least.
-
Install bpi-tools on your Linux PC(if flash image with other tools, ignore this step). If you can’t access this URL or any other install problem, please go to bpi-tools source repo, download 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 -
Download latest Linux Image, and confirm that the md5 checksum is correct.
-
Default login: pi/bananapi or root/bananapi
¶ Install Image to SDcard
Windows PC
Install Image with Balena Etcher.
Balena Etcher is an opensource GUI flash tool by Balena, Flash OS images to SDcard or USB drive.
-
Click on "Flash from file" to select image.
-
Click on "Select target" to select USB device.
-
Click on "Flash!" Start burning.
Linux PC
There are two methods for you to choose from.
-
Install Image with dd command on Linux, umount SDcard device /dev/sdX partition if mounted automatically. Actually bpi-copy is the same as this dd command.
$ sudo apt-get install pv unzip $ sudo unzip -p xxx-bpi-m2_zero-xxx.img.zip | pv | dd of=/dev/sdX bs=10M status=noxfer -
Install image with bpi-tools on Linux, plug SDcard to Linux PC and run
$ sudo apt-get install pv unzip $ sudo bpi-copy xxx-bpi-m2_zero-xxx.img.zip /dev/sdX
¶ Update your image
-
Get the m2 zero bsp source code
$ git clone https://github.com/BPI-SINOVOIP/BPI-M2P-bsp-4.4 -
Build the source code according to the README.md, and update the packages to the sdcard with bpi image flashed.
¶ Advanced Development
¶ How to create an image
-
Prepare a SD card which have installed system(Ubuntu/Raspbian/..)
-
Start with SD card, and after the startup is completed, 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 /mediathen
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
-
On M2 Zero console:
Execute
./adbd.shthen execute
ps -ax | grep adbdto see if adbd is set up
-
On PC terminal:
If adbd was succeed to set up, insert OTG-USB interface to M2 Zero and PC(with Ubuntu system) Execute
adb devicesto see if PC has recognised M2 ZeroP OTG If yes, we could execute
adb shellto connect M2 Zero by adb now
¶ Bluetooth
Use bluetoothctl tool to operate BT Execute
bluetoothctlIf 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
-
Use commands to setup WiFi client
ip link set wlan0 up iw dev wlan0 scan | grep SSID vim /etc/wpa_supplicant/wpa_supplicant.confnetwork={ ssid="ssid" psk="password" priority=1 }wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf dhclient wlan0 -
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 picture taking function
./test_ov5640_image_mode.shTest video recording function
./cameratest.sh¶ Display
How to change display resolution
For Example： we change M2Z HDMI display 1080P.
-
Execute
mount /dev/mmcblk0p1 /mnt cd /mnt/bananapi/bpi-m2z/linuxfind "sys_config.fex"
-
Execute
vim sys_config.fexchange
screen0_output_mode = 5to
screen0_output_mode = 10
-
After save changed, use
fex2bincommand to transfer sys_config.fex to bin file "fex2bin sys_config.fex script.bin",reboot.
parameters meaning：
¶ BPI-Tools
Install Bpi-tools
curl -sL https://github.com/BPI-SINOVOIP/bpi-tools/raw/master/bpi-tools | sudo -E bash -Update Bpi-tools
bpi-tools
¶ RPi.GPIO
