Using Breakpoints During Debugging
Q: Why can't I set more than 2 breakpoints and single stepping does not work properly while debugging from internal flash?
A: When debugging from internal flash memory hardware breakpoints must be used. The TMS320F28xxx devices have access to 2 hardware breakpoints. Stepping also requires setting a breakpoint. Code Composer Studio automatically sets two breakpoints for end of program and CIO preventing you from having any breakpoints for debugging.
