 * Using your USB-Serial Connect debug console on M2M
 
   

Install Bpi tools

• apt-get install pv
• curl -sL https://github.com/BPI-SINOVOIP/bpi-tools/raw/master/bpi-tools | sudo -E bash

Load your first Linux image on SD card

• you could download image from here: http://forum.banana-pi.org/t/bpi-m2m-r16-new-image-release-ubuntu-16-04-2018-08-25/6596
• after download image, copy it to your ubuntu PC
• plug your sd card to your ubuntu PC, and Execute "fdisk -l" to check the SD card drive letter
• Execute "bpi-copy xxx.img /dev/sd<drive letter>"

• Ex: my sd card is recognised as /dev/sdf
• I can use "bpi-copy xxx.img /dev/sdf" to install image on my SD card.

Compile code

• git clone https://github.com/BPI-SINOVOIP/BPI-M2M-bsp.git

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
