|
|
<p>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</code> interface to the board. By default
|
|
<code>xmd</code> uses port <code>1234</code>. (While it is possible to change
|
|
this default port, it requires the use of undocumented <code>xmd</code>
|
|
commands. Contact Xilinx support if you need to do this.)
|
|
</p>
|
|
<p>Use these GDB commands to connect to the MicroBlaze target processor.
