Hi, I want to evaluate Timestamp Generator and conduct an investigation into Timestamp Generator in Vybrid(VF6XX).
In Vybrid F-Series, is the clock frequency of 'Timestamp Generator' same as 'platform bus clock '?
Vybrid contain A5 with ETM from ARM so it is really ARM question. Nevertheless in ARM Information Center in CoreSight ETM-A5 Technical Reference Manual in chapter 2.3.1. Clock signals is written "This must be the same clock as that wired to the CLKIN input of the Cortex-A5 processor." So we can say that timestamp is clocked by Vybrid A5 clock not platform clock.
ETM general info http://arm.com/products/system-ip/debug-trace/trace-macrocells-etm/index.php
Coresight on A5 link http://arm.com/products/system-ip/debug-trace/coresight-for-cortex-a.php there is button to get more information.
