CODECOMPOSER: Replacing a bundle compiler 7.4.14 of an installed CCS 6.1.1 package with an older compiler 6.1.21 - Is it safe?

Is it possible to get a blessing from TI for doing this hybrid CCS setup?

Is there any official comment from TI for this topic?

Hi Ki,

Please provide comments for these cases:

1. CCS 6.1.1 - User Environment Variable not configured by the installer

    "XDAIS_CG_ROOT" - Manually added!

    This patch is required to rebuild some libraries.

2. CCS 6.1.1 + bundle compiler 7.4.14 vs CCS 6.1.1 + stand-alone compiler 6.1.21 - File size difference

   I had problem loading up the second file, here's the contents:

 ---Compiler 7.4.14------                       ----Compiler.6.1.21------

Date       File Size         Lib Name     Date           File Size   Lib Name

8/19/2025   2,236,150    lib1              10/1/2015 3,84`,478   Lib1

                   124,498       lib2                                   152,184 Lib2

                   242,280       lib3                                   315,444 Lb3

Based on my experience and trust TI's IDE tool, compiler 7.4.14 is the obvious choice.

What is this variable pointing to? Is XDAIS being used in your project?

The difference could be related to the debug symbol generation. COFF vs ELF or even differences between the DWARF versions. The key thing is the size of the actual binary loaded to the target.

One particular project has this setting:
Properties > Build > C6000 Compiler > Include Options

"$(CDAIS_CG_ROOT)/packages/ti/xdais"

I assume that the above setting is referring to this folder:
C:\RTN\xdctools_3_31_00_24_core

XDAIS and XDC are different tools. You can get XDAIS from:

https://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/xdais/index.html

Note that XDAIS has been obsoleted long ago and I don't have much expertise on it so I will not be able to provide much support for XDAIS related questions.
