How do I debug multiple instances of MicroBlaze at the same time?

Solution

Up to eight MicroBlaze processors can be debugged simultaneously utilizing a single MDM Core.

Refer to the "Debugging in EDK" chapter of the Platform Studio User Guide at:
http://www.xilinx.com/ise/embedded/edk_docs.htm

There is no specific section on debugging multiple MicroBlaze processors. There is information on how to debug a multi-PPC system. Open several XMD windows, one for each processor. There is a TCP port for each MicroBlaze processor. From GDB, connect to the appropriate processor using the different TCP ports. This procedure is the same for MicroBlaze.

However, this still does not allow you to synchronize stepping of all the processors at the same time. Xilinx does not have a Common Control Interface from which you can issue a Common Command that allows you to control all the processors simultaneously. You can control only one processor at a time when using either GDB or XMD per processor.
