weird "unresolved symbols remain" error in CCSv4

Have you included the DSP2833x_common\source\DSP2833x_DefaultIsr.c file into your project?

This is where these routines are defined.

The fact that source code is provided gives you flexibility if you think you need to modify it.  That said, I firmly believe it is important for you to have a repository of software on your workstation that is viewed as the "prestine copy" which should be unmodified.  This is the version of software as obtained from the vendor (in this particular case, the exact contents of SPRC530 as obtained from TI).

When questions or support is requested of this software, it should be associated with the prestine copy as obtained by the vendor, not any particular modified version.
EDIT : I should clarify this statement a bit.  I don't want to sound like we will not help, or support, you on changes or other code not provided by us, but it should be clearly identified up front in the discussion that the sources are either modified or not modified.  It helps in the understanding of the starting point.

You may very well need to modify the sources for your particular application so having source code is very helpful in that environment.

I know I talking both sides of the equation, but there isn't a single answer.  Bottom line, care needs to be taken when using these resources as to not create unnecessary workload.

I am having a very similar issue.  I am running the trial version of CCS v4 on windows xp.  I imported a 3.3 project to a 4 project.  I recieve the errors below which appears as if the .h files cannot be located but they are all included in my search path.  I've noticed that the errors occur when a variable defined in dsp280x_xxxx.h files are referenced.  Any ideas would be more than helpful.

Kelly,

The first set of undefined symbols such as AdcRegs, CpuTimer0Regs, ECanaLAMRegs are typically defined in a source file named DSP280x_GlobalVariableDefs.c. Can you check that this source file or something equivalent is included in the project?

For the remaining symbols, they should be defined in a library. I see IQmath related symbols, so you probably need the IQMath library and possibly other libraries as well. Please check the  libraries that were part of your CCS 3.3 project and make sure they are all added into the CCSv4 project.

i have same problem with liking files.... help me ... thanks in advance 

Hi,

I'm programming in 28335 and am getting the following error message in the console while building:

<Linking>
warning: creating output section ".ebss" without a SECTIONS specification

error: unresolved symbols remain
error: errors encountered during linking; "Driver.out" not built

>> Compilation failure
gmake: *** [Driver.out] Error 1
gmake: Target `all' not remade because of errors.
Build complete for project Driver

I have included "DSP2833x_GlobalVariableDefs.c" and also "DSP2833x_DefaultIsr.h". Although, the specific ISRs defined in the "DSP2833x_DefaultIsr.h" file have  not been defined except that the following is the content within each function definition:

interrupt void INT13_ISR(void)     // INT13 or CPU-Timer1
{
  // Insert ISR Code here

  // Next two lines for debug only to halt the processor here
  // Remove after inserting ISR Code
  asm ("      ESTOP0");
  for(;;);
}

As we can see, this if required in the program, will not work. I have updated my copy but it gives the same code in the file definition. Please help me with my problem.
