The DSTREAM-XT system
TRACING
Indicates that DSTREAM-ST is attempting to capture data and synchronize with the trace
stream.
TRIGGER
Indicates that a trigger has been detected.
DATA
Indicates that trace synchronization is complete and DSTREAM-ST is capturing trace data.
Trace synchronization is when the DSTREAM-ST unit detects a full synchronization packet
and aligns with the trace data stream.
OVERFLOW
Indicates an overflow-condition during trace capture. An overflow condition occurs if it
has not been possible to stream trace data to the host computer at a high enough rate. For
example, if the USB port is only operating in USB 2.0 mode, if the Ethernet port is only
operating at 100Mbps, or if other applications on the host computer are using too much USB
or Ethernet bandwidth.
When streaming trace data, the best practice is to keep usage of other applications, on the
host computer, to a minimum.
TRC CLK
This LED is for parallel trace only.
If the
TRC CLK
LED is
green
, it indicates that a valid trace clock is detected. This is the normal
condition when capturing trace data from a target.
If the
TRC CLK
LED is
off
, then no parallel trace clock signal is detected.
If the
TRC CLK
LED is
red
and flashing, it indicates that the received trace clock frequency is
too high or too low to be captured.
