linker problem with large CCSv5 C2000 SYS/BIOS project

Andreas

Hello,

I created a relatively large project, including I²C, SPI and Ethernet UDP communications, Clock fuctions, Hwis and Swis. Everything works quite well.

Now, I want to add SD Card FatFs data storage functionality, which needs to include

SDPollDriver.h (e.g.).

The corresponding path is added in the Include Options of the project, but when trying to compile my code, there's a linker error:

undefined          first referenced
symbol                in file
---------          ----------------
SDPollDriver_start ./HAILsensMAINapp.obj

But this can't be because the path should be known to the linker (#include <ti/drivers/SDPollDriver.h>)!?

What's the problem? Are about 30 #includes in the first lines of the main *.c too much?

I tried other functions of the drivers directory with the same result...

What can I do to get it working as it should?

Thanks a lot in advance for your help, best regards:

Andreas,
you need to add a library that defines the symbol SDPollDriver_start to your linker command line. Which product contains SD Card functionality? Is SDPollDriver a RTSC module?

Andreas,

Did you add the following into your .cfg file?

var SDConfig = xdc.useModule('ti.drivers.SDConfig');

or if you are using the graphical method, drag the SDConfig into configuration outline

If yes, can you confirm you can build the "FatFS File Copy example"

Todd,

thanks a lot! I feel a bit ashamed. I added the FatFs, but didn't see the SD option...

Now it compiles without errors.

By the way: The examples are really great and of good help.

Best Regards:

Andreas

PS:

Thank you too, Sasha. I forgot to mention that it worked in the given example and that I added the corresponding linking path.
