Boot System
6.1 Overview
The U-boot address is relocated near to the end of DRAM. The address of U-boot is not fixed
and it varies from release to release based on the type of changes done. It may also change
based on the type of devices that the user has populated on the board.
To get specific address, U-boot can be located within the top 8 megabytes of DRAM. The user
can use the U-boot command 'bdinfo' to display a set of values which includes determining the
location of the U-boot.
The value 'relocaddr' indicates the location of U-boot in DRAM.
The MVME2502 uses Das U-Boot, a boot loader software based on the GNU Public License. It
boots the blade and is the first software to be executed after the system is powered on.
Its main functions are:
 Initialize the hardware
 Pass boot parameters to the Linux kernel
 Start the Linux kernel
 Update Linux kernel and U-Boot images
The below sections describe U-Boot features and procedures that are specific to the
MVME2502. For general information on U-Boot, see

Boot/WebHome .
6.2 Accessing U-Boot
1. Connect the board to a computer with a serial interface connector and a terminal emulation
software running on it
. The serial connector of the board is found on the faceplate.
2. Configure the terminal software to use the access parameters that are specified in U-Boot.
By default, the access parameters are as follows:
 Baud rate: 9600
 PC ANSI
 8 data bits
 No parity
