DRV8301-69M-KIT: Warning null: cannot resolve archive

Mofu Drives

Part Number: DRV8301-69M-KIT
Other Parts Discussed in Thread: C2000WARE

Hello TI,

We are working on 28069F MCU, we compiled the ECAN example code (Example_2806xECanBack2Back) from C2000Ware. Program build with no error but I'm facing a Warning with " null: cannot resolve archive".

In the Console area, these lines are highlighted as a warning.

remark: linking in "IQmath_fpu32_coff.lib" in place of index library
"IQmath_fpu32.lib"
warning: cannot resolve archive

Made changes in the C2000 Compiler and C2000 Linker section from the properties window but not able to solve the issue.

Kindly help in resolving this issue.

Thanks

Hi,

Please refer to this thread: https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/943328/ccs-tms320f280041-tms320f280041-could-not-resolve-index-library-iqmath-lib-to-a-compatible-library

Let me know if you still face issues.

Hi Shanty,

Still, I'm facing the same issue.

remark: linking in "IQmath_fpu32_coff.lib" in place of index library
"IQmath_fpu32.lib"

warning: cannot resolve archive

C:/ti/c2000/C2000Ware_3_04_00_00/libraries/math/FPUfastRTS/c28/lib/rts2800_f
pu32_fast_supplement.lib to a compatible library, as no input files have
been encountered; build attribute information from input files is needed to
determine library compatibility

Thanks

Hi,

Please try the following and revert back:

1) Check if the project is in coff and the rts2800_fpu32_fast_supplement.lib has been built for the coff format. You can change to coff by importing the FASTRTS library and building for COFF.

2) Check if MATH_TYPE is IQ_MATH in IQmathLib.h

3) Check if fpu32 is enabled.

The issue is mostly one of compatibility of object file formats.

Hi Shanty,

Thanks for the reply,

1. Default the project was in coff format only. But should I need to include the rts2800_fpu32_fast_supplement.lib in "linker command file" or should be adding in "runtime supporting library" in the General section from the properties window.

2. MATH_TYPE was IQ_MATH in IQmathLib.h by default.

3.Added fpu32 lib to the project.

But still, I'm seeing the same problem.

If I made any mistakes in steps 1 and 3. Kindly guide me in detail.

Below I will attach the snippet at where the changes are made.

Setp1

setp3.

Thanks,

Hi,

1) You must include rts2800_fpu32_fast_supplement.lib in the C2000 LInker -> file search path -> add lib file. (Please make sure that this lib file is in coff format)

3) I meant FPU32 in processors options.

Thanks, Shanty

Just now verified that fpu32 was enabled.

I include rts2800_fpu32_fast_supplement.lib in the C2000 linker section but how to verify that is in coff format. Kindly help me with that.

Thanks,

Vivishekh

Regarding coff format

0 Shanty over 5 years ago in reply to Mofu Drives

TI__Expert 5410 points

The rts2800_fpu32_fast_supplement.lib is generated by compiling the project found in <FastRTSPath>/c28/ccs/fpu32. Import and compile for coff format, link the lib file that is generated.

In case the issue persists, please share your project files (.project, .cproject files)

Hi,

I was able to replicate your issue. rts2800_fpu32_fast_supplement.lib is an index library that is generated to help pick the correct library versions. This will only happen if you add the compatible library files to the project.

So you need to delete rts2800_fpu32_fast_supplement.lib and add rts2800_fpu32_fast_supplement_coff.lib. I was able to eliminate the warning after this.

Thanks, Shanty

Yes, Now the warning is eliminated after changing the rts2800_fpu32_fast_supplement.lib to rts2800_fpu32_fast_supplement_coff.lib.

Thanks,
