Abstract

A method of tracing a data processor upon reset of the data processor. A data processor reset signal resets the data processor, part of trace collection hardware and does not reset remaining parts of trace collection hardware. The data processor reset signal may be not owned, owned by an application program or owned by a debugger. The partial not reset of the trace collection hardware occurs only upon a data processor reset signal owned by the debugger. A trace logic reset signal resets both the data processor and the trace collection hardware when not owned. This trace logic reset signal resets the data processor only when owned by the debugger and resets the trace collection hardware when owned by an application program.
