Boot System

6.1

Overview

The MVME2500 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

This section describes U-Boot features and procedures that are specific to the MVME2500.
For general information on U-Boot, see http://www.denx.de/wiki/U-Boot/WebHome.

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

1 stop bit

These serial access parameters are the default values. These values can be changed
within the U-Boot. For details, refer to the U-Boot documentation.
3. Boot the MVME2500.
4. When prompted, press the <h> key.
U-Boot aborts the boot sequence and enters into a command line interface mode.
