Blunk's TargetTools includes a debug monitor, TargetMon, that connects
to the debugger (Insight/GDB) via Ethernet.
http://www.blunkmicro.com/tools-cf.htm
Currently, when a breakpoint hits, all tasks are stopped and only the
debug monitor runs, in polled mode with interrupts masked and still
communicating over TCP/IP, but we've had this running in an alternate
mode that just suspends the task that hit the breakpoint and lets other
tasks continue running.
We've had other requests from this, from customers doing motor control
as you are, and will be productizing this mode. If you are interested
in trying our software, we can supply this mode for you.
Best regards,
Tim
