Work with your DSTREAM-ST
To connect a DSTREAM-ST unit to a target without affecting its current state, you must:
1.
Power up the DSTREAM-ST unit. Allow the DSTREAM-ST unit to power up.
2.
Connect the debug cable to the target.
Hot-plugging: disconnecting
When unplugging the debug connector, you must be aware that:
•
If you are using a Return Test Clock (RTCK) system, make sure that no communication is taking
place between the system and the DSTREAM-ST unit. Otherwise, if the DSTREAM-ST unit is
waiting for a return clock, it might lock up.
•
If you are not using an RTCK system, the debug software can handle this situation. However,
you must perform a Test Access Port (TAP) reset using the debugger when you next connect
the DSTREAM-ST unit into a target. For more information on TAP resets, see Reset signals.
