Hello,
Note that the documentation you are following all reference old versions of CCS and DSP/BIOS. The 54x DSP/BIOS User's Guide looks like CCSv2 or earlier. It is also for an old DSP/BIOS version... probably v4.8 or earlier. You should not be using that guide with CCSv5 and DSP/BIOS v5.4 (which is the version that comes with CCSv5).
For a more updated user's guide, see:

Thanks
