OMAP Wireless Connectivity AM335x System startup

This section describes how to boot up the board and get to the Linux prompt. The board is controlled by the PC via a serial port. Therefore a serial port utility should be used from the PC side, and then upon turning the Power switch ON, the board will start booting until getting to the Linux prompt.

Prerequisites

Before starting this step, verify the following:

• The board is connected to the PC via a serial port and is controlled using a serial port application
• The board is not powered up yet

Otherwise refer to: < AM3335x board bringup>, to boot the board.

Serial Port Utility Configuration

In order to communicate with the AM37x EVM board’s serial port console and run the WLAN/BT demos, a serial port terminal program must be installed. The recommended tool is TeraTerm: terminal emulator for Windows.
After connecting the EVM to the AM37x EVM, turn on the serial port utility in the PC and use the following setting parameters:

Baud rate: 115200 
Data : 8 bit
Parity: None
Stop: 1 bit
Flow control: none
Transmit delay msec/char: 1
Transmit delay msec/line: 1

Booting the AM335x Platform

Apply power to the EVM board by turning the electric switch to ON. The following messages should appear on the console:
