5.1 Overview
This product 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 on after it is powered on.
Its main functions are:
 Initialize the hardware
 Pass boot parameters to the Linux kernel
 Starting the Linux kernel
 Update Linux kernel and U-boot images
This section describes U-Boot features and procedures that are specific to the ATCA-F125. For

5.2 Accessing U-Boot
The U-boot can be accessed using the serial interface connector at the face plate of the ATCA-
F125. To connect, you need a computer with a serial interface connector and a terminal
emulation software such as HyperTerm running on it.
1. Connect the console interface connector of the ATCA-F125 to the serial interface connector
of the computer.
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
 Flow control: XON/XOFF
 PC ANSI
