Optimization level gives Data verification failed at address 0x10000

Andy Kong1

I need to do debug of an existing project using TMS320C32. The chip ran ok.

I tried to watch some variable but the value seemed wrong. I saw the project optimization level was LEVEL 1 - local. I assumed the wrong variable value was because of the optimization. (correct me if I'm wrong). I changed the optimization to DISABLE and rebuilt the whole project. But when I loaded the program to the board, it kept giving me this warning. Is it normal? Thanks

Data verification failed at address 0x10000. Please verify target memory and memory map.

And then, another warning at address 0x102D7

After pressing Yes of all these warning (10 minutes), when I tried to run the program, There was another warning

"Warning! No valid program is currently loaded into memory. Do you still want to run?" Any help will be great, thanks.

If I change back the optimization option to LEVEL 1 - local, everything was fine. Why is that? Thanks. For me, I just need to set breakpoint and look at some variable, nothing much.

Hello,

It could be that disabling optimization impacted your code allocation in memory. My first question is if 0x10000 is a valid, writable memory region on your target and if the debugger memory map allows writes to it.
