I am using ccs4.1 to debug PADK board which has c6727B on board. I use latest c6727 csl tool but not dsp/bios. I find a problem that sometimes when i try to use csl function csl_mcasphwcontrol, the program will go to unexpected address. This phenomenon occurs when the .test section is allocated with small address than .far section.

Greetings,
I suggest you start by applying the following particles of TI's patch to your project
-l$(Install_dir)\sprc203\SystemPatch\applySystemPatch.obj
-l$(Install_dir)\sprc203\SystemPatch\c672xSystemPatchV2_00_00.lib
since it does not appear in your memory map.
I believe this patch is needed for all C672x devices. It is under sprc203 on TI's web site.
If you you do get anywhere, then I suggest you run the example project ...\PADK 2.0\DSP\examples\SimpleAudioEffect on your setup to clarify your hardware is good.
Good Luck,
