Page 24: Hot-Plugging And Unplugging The Debug Cable
You might want to connect the debug cable if you have a target that is operating without a DSTREAM unit connected and you want to examine the target to find out why it is behaving in a particular way. To do this, you must power-up the DSTREAM unit and configure the connection without affecting the state of the target. -
Page 25: Tracing With Dstream
DSTREAM to capture trace. DSTREAM is capable of capturing trace data into a cyclic buffer, and you can define the buffer size up to a maximum of 4GB. When a sufficient amount of trace data has been captured to fill the buffer, the FULL LED illuminates.
