The DSTREAM host software
The DSTREAM 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 DSTREAM 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.
•
Enables multiple concurrent connections. 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 debugging multiprocessor systems where the processors interact with each other. For
more information on the capabilities of multicore debug and synchronization, see the DS-5 Debugger
documentation.
•
Supports connections across a network, so that you can run the debugging software on several
different computers.
The DSTREAM hardware and software supports multiple concurrent connections from single or multiple
clients.
