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/UBoot/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 face plate.
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
3. Boot the MVME2500.
4. When prompted, press the "h" key.
These serial access parameters are the default values. These can be changed from within the
U-Boot. For details, refer to the U-Boot documentation.
