Host Setup

1. Connect the Host and the first network port of COMX-P2020 to the network switch, and
set the IP Address on the Host. Here we set the Host IP Address: 192.168.0.197 with
network mask 255.255.255.0.
2. Connect the UART#1 of COMX-P2020 to the host via a cross cable serial connection.
3. Start a terminal such as minicom and set it up to talk to the COMX-P2020 board.
4. Serial Setup:
Baud rate= 115200; Data bits = 8; Parity = None; Stop bits = 1; Flow Control = None
5. Power on the board and check the console prompt.
6. Extract the BSP targets from the compressed BSP tar ball as below:
[percy@localhost current]$ pwd/local/tftpboot/COMX-P2020/current
[percy@localhost current]$ tar zxvf COMX-P2020.bsp.tar.gz
