The default serial port settings are 38400,8,N,1. RedBoot
also supports minimal flash management on the EB40.
However, since the flash device (AT29LV1024) is so small (only the upper 64K is
available for general use), only the simple flash write command 'fis
write' is supported.</para>

<title>Initial Installation Method </title>
<para>
This development board comes with ARM's debug tool, Angel, installed in flash.
At this time, Angel will not be replaced.  Rather, RedBoot will be placed in
the alternate half of flash.  Switch SW1 is used which monitor to boot.  Selecting
SW1 to "lower mem" will choose Angel.  Select SW1 to "Upper mem" for RedBoot once
it has been installed.
</para>
<para>
Set SW1 to "lower mem" and connect serial port A to a host computer.  Using GDB
from the host and Angel on the board, download the RAM mode image of RedBoot
to the board. SW1 should then be set to "upper mem" just before starting RedBoot using
the 'cont' command. Once RedBoot is started, the Angel session must be interrupted (on
Linux this can be done using ^Z).  Follow this by connecting to the board using
minicom at 38400-8N1.  At this point, RedBoot will be running on the board in
RAM.  Now, download the ROMRAM mode image and program it to flash.
