DSTREAM-HT trace probe configuration

As part of configuring trace for your hardware, you can configure HSSTP trace.

Configure the DSTREAM-HT trace probe using the Trace Configuration settings available in the Platform Configuration Editor (PCE).

In PCE, select the configuration file, and then click Debug Adapter > Trace Configuration > Trace Type > HSSTP
