STM CircleOS forum / SWV

Hello,

I recently purchased an EvoPrimer. I have tried the TestSWV example, and as far as I can see, no data is transmitted over SWO.

I have enabled SWO in Rlink->advanced options, and also enabled software traces in Ride7.

Sometimes seems that ITM_SendChar() is getting stuck in the while loop (the port is full), and other times the ITM registers are not correctly programmed (the if statement fails and the port is not written)

I have tried combinations of
RKit
1.36.11.0285
1.38.12.0027

Ride7
7.36.11.0280

STM32F103VG
STM32F107VC

Could this be a problem with the embeded RLink in my EvoPrimer? I assume the ITM is configured by RLink over the SWD interface?

Thanks
Paul

It seems you enable ITM channels in the corresponding menu, but did you start the trace in the trace view ?
Take a look at the "Getting Started with Ride 7 for ARM" document available in the Help Menu.
Last question : which license level did you get ? Normally this functionality is only available with "Entreprise" license

Hi,

You are correct! I only have a Lite license.

Thanks!
