Complex HW Watch Point

Nick Borton

Hello,

I'd like to implement a few relatively complex hardware watchpoints. Somehow when an interface is running at high speed, the source address for a DMA is incorrect. I need to watch the source address pointer and only break when it is outside of a particular range.

I'm working on a C6472, which has an AET unit. Do I need to use the AETlib? or can I specify something like this through code composer? So far I haven't found a way to do this in code composer.

Thanks

No. You only need AETlib if you want to program AET via the running application.

Yes, you can do this.

Digging into the breakpoint / watchpoint properties does provide more options. But I'm looking to implement a "with data outside of range" style of watchpoint. I don't think I can specify that with just data and an OR mask. Maybe I'm not thinking about it correctly.
