The debug host software provides the interface between your debugger and the DSTREAM
hardware that controls the target devices. It translates debugger commands, such as start, stop,
and download, into control sequences for a particular processor. The debug software provides
support for debugging on a wide range of ARM processors. To see a list of supported processors,
open the installed Update utility, connect to your debug hardware, and expand the Templates
tree and sub-trees. A list of templates for all supported processors is displayed.
The debug software can address each target device individually, without affecting other devices
on the board. It uses this ability to create virtual connections for each of the JTAG devices on
the board. Your debugger can attach to one of these virtual connections, and perform debugging
operations with no knowledge of the other devices on the board.
The debug software enables multiple concurrent connections. You can debug multiprocessor
systems. The software can also perform a synchronized start or stop of processors, for
debugging multiprocessor systems where the processors interact with each other. For more
information on debugging, see the documentation that accompanies your debugger.
The debug hardware and software supports multiple concurrent connections from single or
multiple clients. You can debug or control multicore systems from a single client debugger or
you can debug or control distinct devices in the system from separate client debuggers.
Depending on the system, the software can also perform a synchronized start or stop of
processors. For more information on the capabilities of multicore debug and synchronization,
see the documentation that accompanies your debugger.
The debug software also supports connections across a network, so that you can run the
debugging software on several different computers.
