I would like to ask some questions when I using ETM on Juno Board. It is really appreciated it if can give me some answers or tutorials.
What is the ETM Timestamp granularity? Whether it is a nanosecond-granularity timestamp Counter?
whether all ETM of CPU cores share the same time counter to generate a synchronization timestamp?
How can I configure ETM registers to generate maximum timestamp packets as much as possible, and can I generate a timestamp packet before each branch instruction?
Thanks so much for your help and time.
Are you still looking for help with this, or did you manage to find a solution to your question?
