TMS320F28375S: Problem in attaching library in code.

Hi Muzammil,

Did you check the build settings and the included files for the flash programming example project provided in C2000Ware at C2000Ware_5_01_00_00\device_support\f2837xs\examples\cpu1\flash_programming\cpu01 ?

Thanks and regards,
Vamsi 

Hello Vamsi,

I check the example project earlier but i was not able to understand the build settings and how the flies are included. so I started this thread. can you please give some more clarification about how the include flash library and how the libraries and files are included ingeneral?

thanks and regards

Hi Muzammil,

When comparing the screenshots of your project build settings with the build settings of the flash programming example, there are a few differences to note. 

• In the "Include Options" view of the C2000 Compiler, you should be including the Flash API filepath: C2000Ware_Install_Location\libraries\flash_api\f2837xs\include
• In the "File Search Path" view of the C2000 Linker, you should add the C2000Ware_Install_Location\libraries\flash_api\f2837xs\lib filepath
• You don't need to create the Flash API folder in the "device" folder 
• Note: The "../" you see in the filepaths of the flash programming examples are indicating to move "up", or to the parent directory, of that relative location. For example: Path_A/Path_B/Path_C/../../ would result in the final path being Path_A/. Hopefully this clears up any confusion about how the flash programming example includes paths/libraries.

Kind regards,

Skyler

Hello skyler,

I made the changes as mentioned by you in my project but still it is giving the error when i include the <F021_F2837xS_C28x.h> library.

the snapshot of error is shown below

can you please help me solve this error?

is this compulsary to do this in my project also?

Hi Muzammil,

What do lines 67-73 look like in the Types.h file that the error occurs in? I suspect there could be a mismatch in what is defined in your project vs the example. Is __TMS320C28XX__ defined in your project?

Muzammil Qureshi said:

No, as long as your filepaths result in the same destination, there is no need to include the ../ unless you need to navigate "up" a level.

Best,

Skyler

do you mean in predefined symbols options in project settings??

these are the predefined symbols in my project.

I have not defined __TMS320C28XX__   but if I define it in predefined symbols, it gives me more errors.

please help me to solve this problem.

thanks and regards,

Hi Muzammil,

It looks like the ATTRIBUTE_PACKED that was originally marked as an error is defined, so I'm not sure why it shows up as invalid. Don't define __TMS320C28XX__ in the predefined symbols, I was just verifying that it was defined so the ATTRIBUTE_PACKED macro would be defined in Types.h. What compiler are you using?

Kind regards,

Skyler

Hello Skyler,

I am using C2000 Compiler.

Compiler version : TI v22.6.1.LTS.

thanks and regards

Hi Muzammil,

Can you send an updated image of your project structure and the filepaths included? I am unable to recreate this error on my side. 

I am including these Flash API paths in my project and am able to compile with #include <F021_F2837xS_C28x.h> in my main file.

Kind regards,

Skyler

linker ->.

can you please reply by today itself please?

Hello skyler,

I have made separate hal_flash.c and hal_flash.h files for flash operation. i have made the functions which include Fapi library functions in hal_flash.c and declared that functions in hal_flash.h file.

i also include "F021_F2837xS.h" file in my hal_flash.h file.

till then it compiles successfully but when i try to call that functions in main file, it gives me error.

note that i have also included "hal_flash.h" and "F021_F2837xS.h" in my main file.

thanks,

Muzammil Qureshi

Hi Muzammil,

Can you try adding the F021_API_F2837xS_FPU32.lib file to your project directory? Right click the project, select Add Files, navigate to C2000Ware_Install_Location\libraries\flash_api\f2837xs\lib, and select F021_API_F2837xS_FPU32.lib.

Kind regards,

Skyler

Hello Skyler, 

I tried adding the library file as you mentioned above, but still the result is same. still i am getting the error i mentioned above.

is it possible that the error is in linker .cmd file?
