BIOS section warning..

Other Parts Discussed in Thread: CCSTUDIO

Dear All,

 

I am currently working on a project using a DSP/BIOS on CCS V3.3 and Cg Tools V 4.3.6......

And also my BIOS version is 5.31.02.

 

When compiling the project i get the following warning.

warning: Section ".bios" is found in
   "C:/CCStudio_v3.3/bios_5_31_02/packages/ti/bios/lib/bios_NONINST.a55L<fxn_c.
   o55L>", this could cause potential compatibility problem. Please use 4.1.x
   tools or update your DSP BIOS

 

Can some one help me to clear the warnings?

Regards,

Dinesh Davuluru

    Dinesh --

     

    The 4.2.x version of the linker had some different behaviour for the BIOS-generated cfg.cmd file.  BIOS was using some linker.cmd syntax that was not spec'd well and worked differently in 4.1.x from 4.2.x.

     

    5.31 and 5.32 will work with 4.1.x and older linkers.  We have tested with 3.2.x -> 4.1.x.

     

    5.31 and 5.32 will *not* work with 4.2.x and newer linkers.

     

    Bottom line is that we updated our generated .cmd file in BIOS 5.33 to work with linkers from 3.2.x -> 4.2.x.   And we are still clean with 4.3.x.


    You have 2 choices:

     

    (1)  revert your codegen to 4.1.x.

    (2)  update your BIOS to 5.33.00 or newer.

     

    I would recommend the latest 5.41.0x.  Migration should be easy.  Existing .tcf and code should work without change.  Just rebuild your configuration and application.  You will need to update your CCSv3 component manager to point to this release after you install it.
