Chapter 13: Xilinx Microprocessor Debugger (XMD)
R
supports non-intrusive debugging using hardware breakpoints and hardware single-step,
without the need for a ROM monitor like xmdstub.
MDM Target options
When no option is specified to the mbconnect mdm, xmd will automatically detect the
JTAG cable, chain and the FPGA device containing the MicroBlaze-MDM system. If xmd is
unable to detect the JTAG chain or the FPGA device automatically, users can explicitly
specify them, using the following options.
mbconnect mdm [-sim] [-cable <JTAG cable options>] [-configdevice <JTAG chain
options>] [-debugdevice <MicroBlaze options>]
JTAG cable options
x type <cable type>
Valid cable types are: xilinx_parallel3, xilinx_parallel4,
xilinx_svffile
In the case of xilinx_svffile, the JTAG commands are written into a file specified by
the fname option
x port <parallel port name>
