Hi,

Do you have 2 linker cmd files in your project build?

Regards,

Veena

Yes, I have two .cmd files. I am trying to port the code from the universal motor controller lab SDK ,which is written for a f28002x controller. I am trying to replace the  f28002x controller with a F2838D. For porting the code, I am using the this TI document. In the porting instructions (page 70,section 3.3)
, they ask the user to copy the linker CMD files as it is and just rename the linker file. 

After disabling the 2nd linker file for the 2838x, I got the rid of memory overlap errors but now I am getting multiple unresolved symbol errors. 

Hi,

This is not a linker cmd file issue. Please check if you have these function definitions are present in the project, either in .c files or .lib files

Regards,

Veena

What version of the FAST .lib file do you have in your project? Are you seeing any warnings or errors about it? I don't think we support an FPU64 version of the FAST lib, so you may be running into some linking issues because of that.

Do you need FPU64? Could you change your compiler settings to FPU32 and see if that helps get rid of some errors?

Whitney

Hi Whitney,

I don't have FPU64 anywhere, everything is FPU32. See following snippet from my .projectspec file.

The FPU64 was causing this issue. Thanks for the precise and immediate assistance.
