><P
> RedBoot supports the serial port which is available via a special cable connected
to the CON_UART connector on the board. 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.
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
