AWR1843AOPEVM: Error #1965 cannot open source files

Hi,

If you are trying to create a standalone CCS project that uses some of the mmwavelib functions I recommend that you copy all required files locally in the CCS workspace.

Thank you

Cesar

If I understood correctly, for every source file error like above I am to find said file, copy paste it to the workspace and then rebuild. I have done this until I arrive at the same error but now with the file c6x.h and when attempting the same method of copy pasting I then receive a multitude of errors. The first error is the same kind just with another file named mmwavelib_fft.h however everything after that are when the IDE attempts to build other C files that cannot be built because there are multiple identifier errors centere aruond "__int40_t" being undefined I will include a screenshot of the errors. I'm not sure what other header or source file I would have to include as looking through c6x.h I only see one include file being vect.h which is already included in the workspace and adjusted accordingly in c6x.h. Is there anything else I should try or if I even have to include all of these files before beginning my code? 

P.S. I have also included a screenshot of my workspace with the files (and folder) that I have included thus far. 

Hi,

What is the mmwavelib function you try to use? I don't see src code for mmwavelib function included

Thank you

Hello, I'd like to apologize for the late response to this. I have copy and pasted the entire code of what I was working on before this error had popped up on CCS 7.

Hi,

Thank you for the additional information.

Here is what I recommend.

1) Start with an existing test available in

C:\ti\mmwave_sdk_03_06_00_00-LTS\packages\ti\alg\mmwavelib\test

2) Rebuild the test using provided makefile and information in the SDK User Guide

C:\ti\mmwave_sdk_03_06_00_00-LTS\packages\ti\alg\mmwavelib\makefile

3) Modify one of existing tests (or create a new one - in this case you will need to update the makefile as well)

4) Build updated test with makefile

After these steps, we can create a ccs projectspec for this test

5) Create ccs projectspec for this test

The following thread could be useful. It provides information on how to create a ccs projectspec for spi driver.
