Hi Newbee,
ROV is part of CCS and you dont need to separately install it. Here's a screenshot of how to launch ROV:
Check the Tools menu again for ROV.
Once you have ROV open, you can halt the C28 and open Timer view's device tab. This tab shows the current and remaining timer count. This count should change each time you run the core for a while and halt. The Timer ROV view will be helpful in debugging any timer related problems.
Best,
Ashish
