+
+The MicroBlaze is a soft-core processor supported on various Xilinx
+FPGAs, such as Spartan or Virtex series.  Boards with these processors
+usually have JTAG ports which connect to a host system running the Xilinx
+Embedded Development Kit (EDK) or Software Development Kit (SDK).
+This host system is used to download the configuration bitstream to
+the target FPGA.  The Xilinx Microprocessor Debugger (XMD) program
+communicates with the target board using the JTAG interface and
+presents a @code{gdbserver} interface to the board.  By default
+@code{xmd} uses port @code{1234}.  (While it is possible to change 
+this default port, it requires the use of undocumented @code{xmd} 
+commands.  Contact Xilinx support if you need to do this.)
+
+Use these GDB commands to connect to the MicroBlaze target processor.
+
+@table @code
+@item target remote :1234
+Use this command to connect to the target if you are running @value{GDBN}
+on the same system as @code{xmd}.
+
+@item target remote @var{xmd-host}:1234
+Use this command to connect to the target if it is connected to @code{xmd}
+running on a different system named @var{xmd-host}.
+
+@item load
+Use this command to download a program to the MicroBlaze target.
+
+@item set debug microblaze @var{n}
+Enable MicroBlaze-specific debugging messages if non-zero.
+
+@item show debug microblaze @var{n}
+Show MicroBlaze-specific debugging level.
