Getting linker error with CCS v6.1.3 and CC2564 Audio SNK source

Is there a place where i can download COFF version of libBluetopia?

C:\ti\Connectivity\CC256X BT\CC256x MSP430 Bluetopia SDK\v1.5 R2\MSP430_Experimentor\Bluetopia\lib\CCS\LargeMTU\coffabi\libBluetopia.a

C:\ti\Connectivity\CC256X BT\CC256x MSP430 Bluetopia SDK\v1.5 R2\MSP430_Experimentor\Bluetopia\lib\CCS\LargeMTU\eabi\libBluetopia.a

Here even tough i have set to ELF, below message shows still COBF.

1) In the CCS General -> Advanced Settings properties change the Output format from "legacy COFF" to "eabi (ELF)":

The output format tells the compiler and linker to use EABI when build the program.

2) In the CCS Build -> MSP430 Linker -> File Search Path -> library search path properties edit the two ${ProjDirPath} paths to use "eabi" rather than "coffabi":

That makes the linker find the EABI versions of the pre-compiled Bluetopia libraries.

However, when the above two changes were made to the A3DPDemo_SNK project then got different linker errors:

I think these errors are due to the A3DPDemo_SNK lnk_msp430f5438a.cmd linker command file and the pre_init.c source file being written for the sections used by the COFF run-time library, and require changes for EABI.

Given that the A3DPDemo_SNK example was created using the MSP430 v4.0.0 compiler for COFF format, suggest that you install a v4.0.x compiler in CCS 6.1.3 and leave the A3DPDemo_SNK example as using COFF initially and check that works before trying to change to a later compiler and/or EABI.

I was able to install the v4.0.1 compiler into CCS 6.1.3 and build the unmodified A3DPDemo_SNK example without any linker warnings or errors.
