6.5. Trace synchronization in ETMv2

For large trace captures it is likely that the first trace sample is lost from the TPA (overwritten by a newer trace sample) by the time that the trigger event occurs. For this reason it is necessary to periodically output synchronization information so that the decompression of the trace can be accomplished successfully. The ETMv2 trace synchronization mechanisms are described in the following sections:
