I am having a similar issue configuring watchpoints in CCS V5.5.
I tried setting up the watchpoint by setting "Memory Data Bus", but this appears to stop execution whenever a the data bus has a certain value, no matter what the memory address is.
I am trying to break whenever the value at a certain memory address is altered. When I watch the tutorial video, I notice that the "add breakpoint" button in the Breakpoint View has 3 small blue dots, whereas my setup only has a single blue dot. Is this determined by target device, or by code composer version, or by some other configuration parameter?
