I have a program that stopped working. When I build it I get two warnings:

Tech mapping ...

Info: mpr.M0037: Unused pieces of the design have been optimized out. See the Tech mapping section of the report file for details. (App=cydsfit)

Analog Placement ...

Info: apr.M0002: Analog signal "\ADC_DelSig:Net_690\" is connected to one terminal only. (App=cydsfit)

Analog Routing ...

When I place a breakpoint in my interupt routine it is disabled and I can't enable it. Breakpoints elsewhere in my code work fine. The interupt routine is connected to the DMA. This used to work just fine. Any suggestions?

 Could you please attach your design so that we can have a look? To do so, go to 

File--> create workspace bundle -->archive -->attach the zip file

I'm getting this warning

"Warning: Cannot set breakpoint: 'C:\Users\Andy\Documents\PSoC Creator\AA_PP1.cydsn\Generated_Source\PSoC3\ISR_DMA_Done.c:136'.  Encountered error (No debug symobols for file 'C:\Users\Andy\Documents\PSoC Creator\AA_PP1.cydsn\Generated_Source\PSoC3\ISR_DMA_Done.c'.)."

I've included the bundle of my code. I removed some of the files, but the problem persists.

 Hi Andy,

I had issues in opening your project, hence created a new one and added your files to this new project. Also since I had issues in building the project, I had to modified your files (moved functions on top in fft_main.c file and local declaration on top in main.c file). When I tried to debug by adding the breakpoint at line 136 (which is not valid; it moves to line 141), I did not find any issues. Please try with the updated project attached (AA_PP1-000.Bundle01_updated.zip).

Thanks, Aniruddha 

 Sorry, project did not get attached.

 Attaching the project on behalf of anir.

Are you sure?

Bob

 n the touble of attaching project continues!!!! :(

Byte your teeth! Hold on!!!

A (small) hint: Before achiving the project, run a "Clean Project"

Bob

Attaching the project after cleaning.

Thanks Bob. It worked.

Yes... those small hints...

I had a look into the project and there is NO code in the DMA_Done interrupt! So there is no place to put a breakpoint to.

I STRONGLY(!!!) recomend to use a different approach for ISRs: Use the ISR_StartEx(MyIntRoutine) API and have declared

CY_ISR_PROTO(MyIntRoutine);

and defined

CY_ISR(MyIntRoutine)

{

   // Routine Body

}

This always gives you full control and the ISRs are residing in one of YOUR files (main.c) and not buried deep in one of the generated ones.

Happy coding

Bob

CY_ISR will help you out in solving and framing code of interrupts

for example:

CY_ISR(sw_interrupt)
  {
  // blink led here
  }
