Tracing

Depending on the chip the C5000 trace can either be directly output on dedicated trace pins or sent into a
Coresight trace bus using an

ADTF

component. Another option is to store the trace onchip in trace buffers

(e.g. ETB). For further information about Coresight component configuration please refer to

“Setup of the

Debugger for a CoreSight System”

(app_arm_coresight.pdf).

For information about trace hardware setup refer to the

“AutoFocus User’s Guide”

(autofocus_user.pdf).

Controlling the Trace Capture

On the C5x cores the trace capture setup is controlled by the

AET

command group.

Trace Breakpoints

The following breakpoint examples use AET resources:

Broadcast only the execution of the instruction at address 0x4dd84.

; Broadcast only the execution of the specified instructions

Break.Set

<range>

/Program /TraceEnable

; Broadcast only the instructions that perform the specified data access

Break.Set

<address>

<range>

/ReadWrite

/Read

/Write /TraceData

Break.Set

0x1234ABCD

/Program

/TraceEnable
