The DSTREAM logo on the top of the unit illuminates and the STATUS LED begins to flash
when you power up the DSTREAM-ST unit. The DSTREAM logo flashes when you press the
Identify button in any of the debug hardware tools provided with DS-5.
Illuminates to show that DSTREAM-ST is in its ready state. If a critical error is detected, the
STATUS LED illuminates as continuous red. You must reset the DSTREAM-ST unit to the
factory settings before you can continue using it. See
on page 4-30 for additional information.
Illuminates when the unit is accessing its internal flash storage.
Illuminates when a valid target VTRef is detected.
Illuminates when debug data transfer takes place.
Indicates that DSTREAM-ST is attempting to capture data and synchronize with the trace
stream.
Indicates that a trigger is detected.
Indicates that trace synchronization is complete and DSTREAM-ST is capturing trace data.
Indicates an error condition during trace capture. An error might occur when it has not been
possible to stream trace data to the host workstation at appropriate speeds, for example, if the
USB port of the host PC is only operating at USB2.0 speeds or if the Gigabit Ethernet (GbE)
bandwidth is not sufficient.
