BIOS integration question.

Hello,

I have CCS3.3 installed on my computer with bios versions bios_5_31_08 and bios_5_41_10_36.

I have an environment variable named BIOS_INSTALL_DIR and it points to the directory of bios_5_41_10_36 in the CCS3.3 parent directory. 

I installed CCS5 with its newer bios_5_41_10_38. Does CCS5 rely on environment variable BIOS_INSTALL_DIR  or does it use its' bios_5_41_10_38 for building bios projects?

How can I point the CCS5 to use the older version of bios defined by BIOS_INSTALL_DIR ?

    Anatoly,

    For CCS5 you need to set BIOS_INSTALL_DIR only if you are building with makefiles, or are building other products that use DSP/BIOS.  If you are just building with CCS projects it does not need to be setup. 

    When you are building a CCS5 project the version of DSP/BIOS to use is selected via project Properties->General, selecting the proper version from the “DSP/BIOS version” drop down list.

    I don’t know the details, but from the release notes, version 5.41.00.36 does not list that it is compatible with CCS5.  Is there some reason you must use that older DSP/BIOS version with your CCS5 install?

    Thank you for the answer.

    Yes, we have our product on CC3.3, as far as I know the newest version of BIOS for that IDE is 5.41.00.36.

    I need the same project to be compatible in CC5.

    I added the BIOS 5.41.00.36. to CCS5 by going to Window->Preferences->Code Composer Studio->RTSC and added it as a new product.

    In the same window of RTSC I can put a checkbox corresponding the version of a plugin/software I want to use with my CCS5, am I right?

    If I choose other version of BIOS than 5.41.00.38 (which comes with CCS5) and create a new BIOS project from the examples, the CCS5 still creates it with the 5.41.00.38.

    If I change it i Project->Properties->General, the directory the TConf Script Compiler uses is BIOS_CG_ROOT and it is still pointed to  5.41.00.38.

    How can I change the default BIOS version my CCS5 creates projects with, without typing this directory manually for each project?

    Sorry, my mistake. 

    When I change the BIOS version via Project->Properties->General in the dropdown list, the path of the variable BIOS_CG_ROOT changes properly.

    Can you explain the purpose of checkboxes in the Windows->Preferences->RTSC ?

    Thank you.

    Anatoly,

    The properties in Windows->Preferences->CodeComposerStudio->RTSC are general workspace options that are used when no specific project is selected. 

    For example, if one is building SYS/BIOS apps via makefiles (not CCS projects), a CCS debug session can be launched directly, and then these settings can be used for defaults by the RTSC-based tools, for example, for defining a new repository to be used by the runtime object viewer (ROV) tool.  They can be used by other RTSC-based tools as well (like the XDAIS algorithm wizard) that can be launched from the Tools menu.
