$ apt-get install pv
$ curl -sL https://github.com/BPI-SINOVOIP/bpi-tools/raw/master/bpi-tools | sudo -E bash
- 2.After you download the image, insert your TF card into your Linux PC
$ bpi-copy xxx.img /dev/sdx
- 3.After step 2, then you can insert your TF card into W2, and press power button setup W2.
Install Image to SD Card with Win32 Disk Imager On Windows
Install Linux Image to EMMC
- 1.Prepare a SDcard with Linux image flashed and bootup board with this SDcard.
- 2.Unzip the image and copy it to a USB drive, plug the udisk to board and mount it.（If automatically mounted, ignore this step）
mount /dev/sdx /mnt
- 3.There are two ways to install the linux image to board.
- Install with dd command.
sudo dd if=/mnt/xxx.bpi-w2-xxx.img of=/dev/mmcblk0 bs=10M status=noxfer
- Install the linux image in udisk with bpi-tools command
sudo bpi-copy xxx-bpi-w2-xxx.img.zip /dev/mmcblk0
- 4.After download complete, power off safely and eject the SDcard.
Install Android image
Download the latest Android image
Download BPI-W2 USB flash tool
Note：
- 1. BPI-W2 USB flash tool is a usb download tool for flashing android image to board emmc, and only support Windows platform.
- 2. Make sure SW4 switch to '0' for emmc boot.
- 3. Read w2_android_usb_download_tool/document/bananapi_w2_usb_download_tool_guide.doc before flashing image.

PWM Control
SATA
1. Mount dev on W2
- 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"
SSD
1. 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
HDD
1. 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
NetWork
GMAC
- iperf3 -c [server]
- iperf3 -u -c [server]
- iperf3 -s
WiFi & BT
1.If you want to use WiFi or BT, you could use RTL8822BE module.
STA
1. Use commands to setup WiFi client
- ip link set wlan0 up
- iw dev wlan0 scan | grep SSID
- vim /etc/wpa_supplicant/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
AP
Developing
