SystemView parallel to a debugger

matt75 · Nov 21st 2016, 3:49pm

It was written that 'SystemView can run in parallel to a debugger'.
But I encounter problems using debugger and SystemView.

My environment is Ubuntu 14.04, IDE Rowley Crossworks, SystemView (systemview_2.40.1_x86_64.deb), target ARM cortex M3 using SV 2.40.

When I use debugger and than I start SystemView I get:

SystemView window:
Failed to start recording. Could not connect.

terminal:
*** J-Link V6.10m Error ***
Second debugger connection to the same J-Link detected.
J-Link currently uses target interface SWD while current debugger tries to select target interface JTAG.
Should interface be changed?
*** J-Link V6.10m Error ***

Debugger:
Rowley CrossWorks - halts the program
and also tested JLinkDebugger which also halts the program

But when I start program using JlinkExe and then SystemView, it works perfect.

What can be a reason?

Hi,

As the message indicates the debugger connection in Rowley uses JTAG,
while you selected SWD in SystemView.
Could you make sure the debugger interface is identical for both connections and try again?

Best regards
Johannes
