Hi Chunyan,
Data trace is not generally available on A profile cores - the A5 & A7 cores are the exception and these use ETMv3.5. The remaining v7 A profile cores use PTM (which has no data trace). All v8 A profile cores use ETMv4 - the ETMv4 architecture specifically excludes data trace support on A profile cores.
ETMv3/4 data trace is being implemented for the cores that do support it, which are in general R & M profile cores as you said.
Regards
Mike

Hi All,
I remember that Mathieu and Al said that data trace is no longer supported on A profile cores except A7 (i.e. ETMv3). But I noticed that the ETMv3/v4 data trace was mentioned again in README [1] - "Support to be added". What does the "data trace" in [1] refer to. Is it only for the ETMv3/v4 on M / R profile cores?
Thanks, Chunyan
