Can't Set Breakpoint at 0x3d87cd: Error 0x00000008/-2047 Error during: Break Point,  Unable to set hardware breakpoint at 0x003D87CD. All hardware breakpoints are already in use. Some hardware breakpoints may be used by analysis.   Sequence ID: 7 Error Code: -2047 Error Class: 0x00000008 

Invalid CIO command (142).  Can't read memory at address (0x8dc0), please check the memory map.

出现上述问题，是因为：When debugging from internal flash memory hardware breakpoints must be used. The 28x devices have only 2 hardware breakpoints. By default, Code Composer Studio automatically sets two breakpoints for end of program and C I/O preventing you from having any breakpoints for debugging.

解决方法：These breakpoints can be disabled by navigating to CCS menu Option -> Customize -> Program/Project/CIO and enabling the two checkboxes titled Do Not Set End of Program Breakpoint At Load and Do Not Set CIO Breakpoint At Load. Close and restart CCS and now you should have access to the 2 breakpoints.
