CCS/TMS320F28377D: CCS v720: Build warning code 99922

Hideaki Nambu

Part Number: TMS320F28377D

Tool/software: Code Composer Studio

Hello,
My customer experienced the following warning message and asked me the explanation and solution. Could you please advise?

>>>
Description Resource Path Location Type
#99922 C:\Users\Y539C~1.AAA\AppData\Local\Temp\{97BB1AE6-821C-4D55-8538-A56AD92B3B80}: Invalid CIE reference 0xffff0000 for the FDE at offset 0x00007466 in the .debug_frame section() AAA_AAA_AAA C/C++ Problem

<<<

(Note: "AAA" was customer-specific strings.)

- Background:
- From a successful project, some source files were selected to be converted to a library.
- A new project was created, the source files were put in, built. None of concerned problems here.
- The newly generated library file came back to the original project.
- The original project was built again -- Then the warning was generated.

- The error code 99922 -- None of clear hits on E2E and CCSv730 help.

To understand what happened, I need to reproduce this diagnostic ...

I presume it is emitted during the link step. That being the case, the best way to reproduce the diagnostic is with the CCS project. Please submit it. See the article Project Sharing for the details of how to create a zip file. Then attach that file to your next post.

Thanks and regards,

The closest thing I can find is CODEGEN-2399, but that involves mixing object files generated by the TI compiler with object files generated by another vendor. I'd need to see the object files in question to analyze the issue further.

George and Archaeologist,

Thank you for your replies.

I duplicated the warning code and uploaded both the lib and main() projects.

CCS ver is 720 for my customer, 730 for me. Please tell me if it concerns.

The original project was blinky_cpu01.

The warning message in my CCS:

warning #99922:

C:\Users\123\AppData\Local\Temp\{8E77B2DA-FDA0-44BB-8345-63DCBAC9D8B3}:

Thank you for submitting a test case. I can reproduce the problem. I filed CODEGEN-4311 in the SDOWP system to have this investigated. You are welcome to follow it with the SDOWP link below in my signature.

Note the diagnostic is a warning, and not an error. An executable .out file is created. I'm sure it works. Though there might be some minor problems with debugging it.

Thanks and regards,

-George

George,
Thank you for your inputs.
We would wait for the investigation result.

p.s. I corrected the title: CCS v720: Build {error warning} code 99922

Tell the user to upgrade to the TI C2000 compiler version 16.9.6.LTS or higher and check if the problem persists.

The problem here is that the user is feeding at least one object file compiled with C2000 16.9.6.LTS into the 16.9.4.LTS linker, which is not a supported use case. Part of the fix for CODEGEN-2399 was to fix the alignment and size of CIE and FDE entries in .debug_frame. This change is forward-compatible, but not backward-compatible. Thus, because one of the object files was compiled with 16.9.6.LTS, linker version 16.9.6.LTS or higher must be used.

Archaeologist,
Thank you for your input.
It solved my projects. My customer will try also.
