I am using the JTRACE PRO on an NRF52 (Cortex-M4). When connecting it to JTRACE and Ozone, Ozone returns back timestamp for every assembly instruction traced. I tried using the JLINKSDK Python package and it returns all the traced instructions but only a selected number of timestamps. For 200 instructions traced, only 4 had timestamps.

My questions are:

1- Based on what is the assembly instruction traced getting a timestamp or not?

2- Is there a way to retrieve the timestamp for every assembly instruction in JLINKSDK Python package to have a similar behavior as Ozone?

Thanks in advance!
