* Trace memory consists of three part.
|
|
*
|
|
* 1. Trace memory header: This describes the layout of trace memory,
|
|
* and latest activities.
|
|
*
|
|
* 2. Exception memory: This is an array of exception entries. Each
|
|
* entry describes an exception occurred in the firmware.
|
|
*
|
|
* 3. Event memory: This is an array of event entries. This is implemented
|
|
* as a ring buffer.
|
|
*
|
|
* The next index gets updated when new messages are committed to the
|
|
* trace memory. The next index points to the entry to be written to
|
|
* at next occurrence of the exception or event.
