Emerson ATCA-S201 manual Network boot procedure, Uboot= saveenv

RTM-ATCA-SXXX Overview

To manually establish IP port address, a typical new system configuration might consist of the following commands:

uboot=> setenv ipaddr 192.168.1.211 uboot=> setenv gatewayip 192.168.10.1 uboot=> setenv netmask 255.255.255.0 uboot=> setenv ethprime eTSEC2

Once all of the environment variables have been modified they persist only if permanently recorded in the flash device. This is accomplished with this command:

uboot=> saveenv

This example setup establishes initializes the 1Gb Ethernet port located on the RTM for administrator login and management access.

3.7Network boot procedure

The ATCA-S201 supports network boot which allows the user to bypass code contained on the embedded flash devices, and instead load code images contained on the network. Network boot does not replace stored user configurations. Network boot requires that the network node supports tftp and must contain the following source files located in directory named /tftpboot/:

Flash contents

U-bootcode

Linux kernel code

Filesystemcode

User configuration settings

Source file name

U-boot.bin

uImage

Rootfs.ext.gz.uboot

...

Hit any key to stop autoboot: 5 uboot=> run ramboot

Note1: Network boot defaults to the Ethernet resource on the RTM. Alternatively, the user may designate the zone-2 Base ports. Use setenv to change the ethprime variable to accomplish this.

Note2: Use setenv to change the serverip variable to the tftp server IP address.
