> RedBoot supports both serial ports, which
are available via the stacked serial connectors on the mother board in
the case of the FR400 CPU board, and via serial connectors present on
the other supported CPU boards themselves. The topmost port is the
default and is considered to be port 0 by RedBoot. The bottommost
port is serial port 1. The default serial port settings are
115200,8,N,1. The serial port supports baud rates up to 460800, which
can be set using the <B
CLASS="COMMAND"
>baud</B
> command as described in
<A
HREF="redboot-commands-and-examples.html"
>Chapter 2</A
>. </P
><P
>FLASH management is also supported, but only for the FLASH device in IC7.
This arrangement allows for IC8 to retain either the original Fujitsu board
firmware, or some application specific contents.
Two basic RedBoot configurations are supported:

>The RedBoot image occupies flash addresses 0xFF000000 - 0xFF03FFFF. To
execute it copies itself out of there to RAM at 0x03E00000. RedBoot
reserves memory from 0x00000000 to 0x0001FFFF for its own use.
User programs can use memory from 0x00020000 to 0x03DFFFFF.
RAM based RedBoot configurations are
designed to run from RAM at 0x00020000.</P
