This section describes the steps to use a third party debugger on the ARM926EJ-S within the device. The

debug capabilities and features for ARM are as shown below.

ARM:

•

Basic Debug

– Execution Control

– System Visibility

•

Advanced Debug

– Global Start

– Global Stop

•

Advanced System Control

– Subsystem reset via debug

– Peripheral notification of debug events

– Cache-coherent debug accesses

•

Program Trace

– Program flow corruption

– Code coverage

– Path coverage

– Thread/interrupt synchronization problems

•

Data Trace

– Memory corruption

•

Timing Trace

– Profiling

•

Analysis Actions

– Stop program execution

– Control trace streams

– Generate debug interrupt

– Benchmarking with counters

– External trigger generation

– Debug state machine state transition

– Combinational and Sequential event generation

•

Analysis Events

– Program event detection

– Data event detection

– External trigger Detection

– System event detection (i.e. cache miss)

– Debug state machine state detection

•

Analysis Configuration

– Application access

– Debugger access
