2 Deploy Development Environment

You need to install the Linux operating system on the PC. It is recommended to use Ubuntu 16.04 64bit distribution, 8G memory,

at least 200G (recommended 500G or more) idle hard disk, connect the network cable and configure the network. Follow-up

operations need to connect to the Internet to install or download related software packages.

Connect development board with PC

1.  PC use USB to TLL cable with DEBUG port(JP25) on board.

2.  Open serial program with exist serial device

PC serial port configure parameters:

Baudrate: 115200

Data bit: 8bit

Parity: None

Stop bit: 1bit

Flow control: Disable
