Hello,
I am not sure how it works dirrectly from S32DS as I was not able to get it working.
But I never used S32DS to start Trace32 powerview,
Simply start the powerview from T32 folder and then execute programming script from menu.
Here you will find programming script. Just execute it in Powerview and program the device.

I will check meantime if I can get it up and running trough S32DS.
Best regards,
Peter
