problem about c6727b csl

bo peng1
Prodigy 30 points

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,
