I have just begun to use Code Composer 4. I have been trying to use the Data Breakpoint/Watchpoint functions in it. I need to have it break when certain addresses are being written to or read from.
From what I have been reading watchpoints don't appear to work on CCS4 when using a C2000. Am I right in thinking this? If this is true can you see any possible solutions to being able to break when RAM addresses are being written or read?
I don't know if this is pertainent, but I am currently using the 30 eval version of CCS4.
Thanks you.
The data watchpoint/breakpoint capability is currently not supported in CCS v4. It is supported via the C28x Emulator Analysis in CCS 3.3 but this support is not yet in CCS v4 but is planned to be in the near future, although I don't know the exact timeframe.

A follow-up on this, the data watchpoint is now available for C28x in the CCS 4.1.3 release. I put a short Wiki page together to get folks started. I'll add more to it as I have time.

I meant 4.1.2 :)

Cheers,
Is it possible to set a watchpoint on a range of addresses? Basically I want to mask some of the address bits so the watchpoint will trigger within a range of addresses. I think this is possible in CCS3.3 but I can't see how to do it from the properties window in CCS4.

Reuben,
The hardware supports it, but CCS4 does not as of the moment. the functionality is similar to that on a 55x, where you can specify a mask for specific bits. There are no range comparators like there are on the 64x.

I couldn't find a CQ # for this, so I've submitted SDSCM00037743
