Figure 2–27 shows how the OMAP5910 ETM is used in a system setup for

capture of trace data.

The TI Code Composer Studiot Integrated Development environment (IDE)

software, trace port analyzer (TPA), and the emulation probe hardware are

used for tracing and displaying the MPU operation.

Agilent provides two types of trace port equipment:

Dedicated trace port analyzer (TPA) (E5903A #301)

A 16700A series logic analyzer used with an analysis probe

(E9595A#002)

The Code Composer Studio IDE provides support only for the TPA setup.

The Code Composer Studio IDE provides a complete interface to the ETM,

including the setup of the trace registers, trigger points, and sequencing of

trace operations. When a trace trigger occurs, Code Composer Studio IDE

decompresses and formats the trace information for display. In addition, when

the TI software development tools are used, Code Composer Studio IDE can

also correlate trace data back to the source code, thus providing complete

symbolic trace capabilities. All of the ETM functions operate in parallel with the

standard debug features provided by Code Composer Studio IDE, such as

breakpoints, single-stepping, etc.
