CCS/TDA3XEVM: lost function

Part Number: TDA3XEVM
Other Parts Discussed in Thread: SYSBIOS

Tool/software: Code Composer Studio

I am transferring DSS example from PDK to CCS7 form. Linker says:

Undefined reference to 'ti_sysbios_hal_Cache_inv__E' in file ./bsp/bsp_osal.obj

This function appears on BIOS header

C:\ti\bios_6_50_01_12\packages\ti\sysbios\hal\Cache.h

as extern point to empty interstellar:

/* inv__E */
#define ti_sysbios_hal_Cache_inv ti_sysbios_hal_Cache_inv__E
xdc__CODESECT(ti_sysbios_hal_Cache_inv__E, "ti_sysbios_hal_Cache_inv")
__extern xdc_Void ti_sysbios_hal_Cache_inv__E( xdc_Ptr blockPtr, xdc_SizeT byteCnt, xdc_Bits16 type, xdc_Bool wait );

And there is no any c-file with proper function source. Does anybody know how to work with such obstacles?
