Why I can't set hardware breakpoints in the CCS3.3 project program?

Bryan,

Assembly vs C shouldn't matter.  There are limited resources to set hardware breakpoints.  You can set 2 hardware breakpoints - but this did not change between CCS revisions (it is a silicon feature).  

Something to try is to go into the CCS setup and disable the end of program breakpoint:

• Go to Option -> Customize -> Program/Project/CIO.
• Check the two boxes titled "Do Not Set End of Program Breakpoint At Load" and "Do Not Set CIO Breakpoint At Load".

Hi, all     

         In my recent project with CCS 3.3 and TMS320F2812, it is very strange that I can't set breakpoints in the CCS project program. My program was written in assembly language,  when I flash the program into ROM and found that I can't set the hardware breakpoint in ROM. I did the following test to verify the problem:

        1、In CCS2.2, I could set the hardware breakpoint in ROM, no matter whether the program was written in C or assembly language.

        2、In CCS3.3, I could only set the hardware breakpoint in ROM when the program was written in C language.

       So, my question is does the CCS3.3 support hardware breakpoint in ROM when the program is written in assembly language?
