TMS320F28035: Error after adding EPWM and GPIO

robin gangopadhya18

Hello Experts

It had three EPWM and GPIO used in the actual code. For my application, I have added another 4 EPWM and 4 GPIO. That's the only change I have made. Even In the include option, all paths are the same as earlier code; also not change in the ".out" file. But after that, when I tried to build it, I have these errors. can you please tell me why these errors appear? and how to resolve it?

Thanks

Robin,

I see no errors. Not knowing the error, here is my advice:

Start with a clean or rebuild the project, this can get rid of old stuck errors.

If that doesn't work, I've had some success removing the project from and adding the project back to CCS.

Could be a real error though, that will need to be addressed, please describe the error.

Regards,
Cody

Robin, you have undefined symbols, probably a variable name or structure.

This is commonly related to linking, but if you made no changes then its probably unrelated. Look back at the build console and it should indicate what symbols are undefined, define them or correctly like to files which define them and you should be good to go.

Cody,

I didn't change anything just change in the main file (epwm and gpio added) nothing else, still get the errors. How it can be possible with the linker.

The errors may be erroneous, I would try starting a new workspace and importing the project to see if the errors go away.

If you want to know what is actually being marked as undefined then you need to go look at the build console, the information found there may point you to an error you didn't expect to exist.
