Why can I not trace with a 4-bit or 8-bit data port width?

Applies to: RealView Development Suite (RVDS)


RealView Debugger (RVD) v3.0 and RVD v3.0.1 have a bug which prevents trace from being enabled unless your target's ETM implements a 16-bit data port width. On targets which only support 4-bit and/or 8-bit data port widths, you will receive Error V20017 Logic Analyzer is not setup when attempting to connect the trace analyzer and configure RealView Trace (RVT):

To remedy this problem, please install the RVD v3.0.1 build 321 patch.


This build of RVD allows you to connect to ETM targets that only support 4-bit and/or 8-bit data widths.  Please note that this patch can only be applied if you have already upgraded to RVDS v3.0 Service Pack 1.
