DSTREAM-HT Getting Started Guide
To connect a DSTREAM-HT system to a target without affecting its current state, you must:
1. Power up the DSTREAM-HT system. Allow the DSTREAM-ST and HSSTP probe to boot up.
2. Connect the HSSTP trace cable to the target.
3. 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-HT system. Otherwise, if the DSTREAM-HT
system 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-HT system to a target. For more information on TAP resets, see
