CCS/CC1350: SDFatFS Linker Unresolved symbol

Carlos Velez23

Part Number: CC1350

Tool/software: Code Composer Studio

Hello,

I'm trying to use the third party SDFatFS library to write/read an external SD card, but every time I build my project, I get errors saying:

unresolved symbol disk_register, first referenced in C:/ti/simplelink_cc13x0_sdk_2_40_00_20/source/ti/drivers/lib/drivers_cc13x0.aem3<SDFatFS.oem3>

unresolved symbol disk_unregister, first referenced in C:/ti/simplelink_cc13x0_sdk_2_40_00_20/source/ti/drivers/lib/drivers_cc13x0.aem3<SDFatFS.oem3>

I'd appreciate some help on this one.

Thanks

Please look into this post: e2e.ti.com/.../766011 and see if that solves the issue.

I tried but it does not solve my issue.
I tried something different.
I started with the empty example. I just added the following lines:
-"#include<ti/drivers/SDFatFS.h>"
-SDFatFS_init();

And I get these two messages:
unresolved symbol SDFatFS_config, first referenced in C:/ti/simplelink_cc13x0_sdk_2_40_00_20/source/ti/drivers/lib/drivers_cc13x0.aem3<SDFatFS.oem3>
unresolved symbol SDFatFS_count, first referenced in C:/ti/simplelink_cc13x0_sdk_2_40_00_20/source/ti/drivers/lib/drivers_cc13x0.aem3<SDFatFS.oem3>

I'm a bit confused.

Did you get exactly the same compilation errors when you added the changes I recommended in the thread I linked to?

Yes, I got the same errors. The linker still identifies it as unresolved sysmbol.

One of the errors indicate that the definition for SDFatFS_config is missing.

Could you show where you included

	
SDFatFS_Object myObj;

SDFatFS_Config SDFatFS_config[] =
{
    { &myObj },
    NULL
};

in your code?

I tried to include in different places. As I mentioned, I used the EMPTY example for CC1350-LAUNCHPAD. I included it before the int_main(), later inside the main before initialization. I would really like to use this SDFatFS libray. Where should I include these definitions??

"Include different places" is not a good problem description. Please provide code that fully shows how you have included the required lines of code.

Thanks for the help. I exported again the example and included step by step everything and now I don't get any problem.
