OMAP Wireless Connectivity AM18x System startup

This section describes how to boot up the board till getting to Linux prompt. the board is controlled by the PC using the serial port therefore a serial port utility should be used in the PC side and then upon turning the Power switch ON, the board will start booting till getting to the Linux prompt.

Prerequisite

Before starting the Calibration, it is assumed that the board is connected to the PC and controlled via the serial port with the serial port application, also that the board is already booted and got to the Linux prompt. otherwise refer to the < AM18x board bringup> In order to boot the board

Serial port utility configuration

A serial port terminal program should be used to communicate with the AM18x EVM board’s serial port console. This tool is needed to run the WLAN and BT demos. TeraTerm is the recommended terminal emulator for Windows.
after connecting the EVM to the AM18x 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

System startup

• Power on the AM1808 EVM board.
• On the console terminal, hit any key when it prompts, to stop at the ‘uboot’ prompt.
• Set the following boot parameters as below.

u-boot :> setenv ethaddr ‘<write down the Ethernet address on the board>’
The Ethernet address looks like xx:xx:xx:xx:xx:xx
u-boot :> setenv bootcmd 'if mmc rescan 0; then if fatload mmc 0 0xc0600000 boot.scr; then source 0xc0600000; else fatload mmc 0 0xc0700000 uImage; bootm c0700000; fi; else sf probe 0; sf read 0xc0700000 0x80000 0x220000; bootm 0xc0700000; fi'
u-boot :> setenv bootargs 'console=ttyS2,115200n8 root=/dev/mmcblk0p2 rw rootwait ip=off'
u-boot :> saveenv

• To see the parameters that was set type 'pri' + enter.

• The board set up has been completed now. You can run 'boot' command to start loading from SD card ( see explanation for preparing SD card ).
• Boot sequence will look like this:
