First, install the Serial debugging tool: Minicom
The Development Board has a serial port. Can be connected to the PC via serial cable. The Linux driver sends debug information to the PC via a serial cable while outputting debugging information, so the Linux driver can view debug information directly on the PC.
Note: Since many new PCs and laptops do not have a serial port, it is recommended that readers buy root USB to serial cable (be sure to buy good quality, otherwise you may receive data garbled or simply unable to receive data). Many USB-to-serial lines in Ubuntu Linux 10.04 and later do not need to be installed to drive to be recognized.
1th Step: Detect whether the current system supports USB to serial port
# Lsmod|grep Usbserial
2nd Step: Install Minicom
# Apt-get Install minicom
3rd Step: Configure Minicom
# Minicom–s
The configuration is as follows:
After Setup, select the "Save Setup as Df1" and "Exit from Minicom" as shown.
4th Step: Test minicom
# minicom
Second, burn write Android system
Detailed information is available in the Development Board manuals and lab manuals.
Third, configure the wired network
1) Set PC host IPV4 address is 192.168.1.2 (IP address can be selected according to the actual situation)
2) Connect the Development Board and the host's serial port, the network port, start the Development Board, after the system starts, set the Android IP address
And the host in the same network segment, for example, enter in a string:
Ifconfig eth0 192.168.1.130 (IP address can be determined according to the actual situation)
To test the Ethernet connection, enter in the string:
Ping 192.168.1.2 (Dev board ping PC)
Or, in the cmd window of the PC, enter:
Ping 192.168.1.130 (PC Ping Development Board)
You can then see the results of the ping command execution.
The fifth chapter constructs the test environment of the Development Board
