<title>Initial Installation Method </title>
<para>A Windows utility
(<application>exc_flash_programmer.exe</application>) is used to
program flash using the ByteBlasterMV JTAG unit.
See board documentation for details on
in situ flash programming. </para>
<para>For ethernet to work (under Linux) the following jumper
settings should be used on a REV 2 board: <literallayout>
SW2-9    : OFF
U179     : 2-3
JP14-18  : OPEN
JP40-41  : 2-3
JP51-55  : 2-3

<title>Flash management</title>

<para>The ROMRAM and REDBOOT configurations supported on this platform
differ only in the memory layout (ROMRAM configuration runs RedBoot from
0x00008000 while REDBOOT configuration runs RedBoot from 0x07f80000). The
REDBOOT configuration allows applications to be loaded and run from
address 0x00008000.</para>

<title>Special RedBoot Commands </title>
<para>The <command>exec</command> command which allows the loading
and execution of Linux kernels,
is supported for this board (see <xref linkend="executing-programs">). The <command>
exec</command> parameters used for the Excalibur are:</para>
<variablelist><varlistentry>

<listitem><para>Length of initrd ramdisk</para></listitem></varlistentry>
</variablelist>

<para>The parameters for kernel image base and size are automatically
set after a load operation. So one way of starting the kernel would
be:

<screen>RedBoot&gt; <userinput>load -r -b 0x100000 zImage</userinput>
Raw file loaded 0x00100000-0x001a3d6c
RedBoot&gt; <userinput>exec -c "console=ttyUA0,57600"</userinput>
Using base address 0x00100000 and length 0x000a3d6c
Uncompressing Linux.....
</screen>

An image could also be put in flash and started directly:

<screen>RedBoot&gt; <userinput>exec -b 0x40400000 -l 0xc0000 -c "console=ttyUA0,57600"</userinput>
Uncompressing Linux.....

<title>Building eCos Test Cases to run with old RedBoots</title>
<para>If using older versions of RedBoot, the default configuration for
EBSA-285 will send diagnostic output to the serial line only, not over an ethernet
connection. To allow eCos programs to use RedBoot to channel diagnostic output to
GDB whether connected by net or serial, enable the configuration option  <programlisting>
CYGSEM_HAL_VIRTUAL_VECTOR_DIAG
"Do diagnostic IO via virtual vector table"</programlisting> located here
in the common HAL configuration tree: <programlisting>"eCos HAL"
     "ROM monitor support"
          "Enable use of virtual vector calling interface"
              "Do diagnostic IO via virtual vector table"</programlisting>Other
than that, no special configuration is required to use RedBoot. </para>
<para>If you have been using built-in stubs to acquire support for thread-aware
debugging, you can still do that, but you must only use the serial device
for GDB connection and you must not enable the option mentioned above. However,
it is no longer necessary to do that to get thread-awareness; RedBoot is thread
aware.</para>
