Hi there,
We have a Cortex-M33 and the coresight module is configured such that ITM traces are output on 2 pins of trace port TRACECLK and TRACEDATA[0], rather than the more traditional SWO pin.
So I have two questions please:
Is there any way (trace window or GUI) to capture ITM traces in ARM Development Studio using DStream for example? Or can this only be done on Keil MDK (uvision IDE) using Ulink-pro?
How do we configure the IDE trace capture to use only one bit (i.e. TRACEDATA[0]) of the four-pin trace port (on the connector)?
Thanks
Sarah
Hi
Sorry, but SWO is not supported by Arm DS or DSTREAM.
To use SWO, you will need to use the Keil MDK and one of the uLink-family probes instead.
