21.3.4 MicroBlaze
-----------------
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 'gdbserver' interface to the board. By default 'xmd' uses port
'1234'. (While it is possible to change this default port, it requires
the use of undocumented 'xmd' commands. Contact Xilinx support if you
need to do this.)
Use these GDB commands to connect to the MicroBlaze target processor.
'target remote :1234'
Use this command to connect to the target if you are running GDB on
the same system as 'xmd'.
'target remote XMD-HOST:1234'
Use this command to connect to the target if it is connected to
'xmd' running on a different system named XMD-HOST.
'load'
Use this command to download a program to the MicroBlaze target.
'set debug microblaze N'
Enable MicroBlaze-specific debugging messages if non-zero.
'show debug microblaze N'
Show MicroBlaze-specific debugging level.
