    Hi,

    What OS is used on your laptop? Which SDK did you use to develop your C6748 code?

    Best Regards,
    Yordan

    Try using the latest CCS version. Or at least the recommended by Processor SDK RTOS: CCS v7.4

    Hi All

    We tried migrate to Starterware - C6748_StarterWare_1_20_04_01

    run into problems with linker got:

    "./configPkg/linker.cmd", line 137: error #10099-D: run placement fails for

    object ".far", size 0x639f1 (page 0). Available ranges:
    >> Compilation failure
    L3_CBA_RAM size: 0x20000 unused: 0x12a7a max hole: 0x12a6c
    error #10010: errors encountered during linking; "NanoScan2Debug.out" not
    built

    looking at the map file

    we see:

    where far.1 looks undefined and giving the length

    of 00056380

    thanks

    There are probably some files missing from your NanoScan2Debug project.. Recheck your project configuration for missing headers & c files.

    Maybe the CCS messed up the project paths when you installed the new version of Sysbios and you did not clean the old one first. I've had similar problems when doing this with RTOS sdk. The easiest way to fix it was to delete everything (backuping my custom projects beforehand) and install it from scratch.
