Part Number: TMS320C6748
Other Parts Discussed in Thread: SYSBIOS

Tool/software: TI C/C++ Compiler

Hello Champs,

Customer installed NDK, NSP as follows. 

                    D:\ti\nsp_1_10_03_15
                    D:\ti\ndk_2_25_00_09
                    D:\ti\bios_6_35_04_50
                    D:\ti\xdctools_3_25_03_72

He failed to build the D:\ti\nsp_1_10_03_15\packages\ti\ndk\examples\ndk_evm6748_elf_helloWorld in CCS v5.5.

He had added the os.ae674 library to project. 

Is there something else he missed to configure?

Thanks.

    The os.ae674 library is not the one that contains the ti_sysbios_knl_Task_*() and ti_sysbios_knl_Semaphore_*() function definitions.  The SYS/BIOS library contains these symbols.

    Your customer shouldn't need to manually add

    -l"D:\ti\ndk_2_25_00_09\packages\ti\ndk\os\lib\os.ae674"

    to the command line.  That library reference is contained in the configPkg/linker.cmd file.  The SYS/BIOS library should also be referenced in the configPkg/linker.cmd file.  Since these undefined references are cropping up, I suspect that they don't have that SYS/BIOS reference.

    In the project's Properties, there is a RTSC tab on the General page.  That tab contains a "Products and Repositories" tab, and in that tab is a list of products and repositories.  Does the customer have a SYS/BIOS entry checked?

    Regards,

    - Rob
