Unsupported ELF flags in MAC library from MKW2xD MCR20A Connectivity Software

Question asked by Joris Vergeer on May 9, 2016


Hi,

 

The new "MKW2xD MCR20A Connectivity Software 1.0.0" contains libraries that IAR 7.30 cannot handle.

 

 

The error I got from IAR during linking was: Internal Error: [CoreUtil/lGeneral]: Illegal value for Tag_ABI_VFP_args

 

I investigated the issue and it looked like the libraries in the "MKW2xD MCR20A Connectivity Software 1.0.0" have

Tag_ABI_VFP_args: compatible

in their ELF File Attributes

In earlier versions of the library this flag was absent and was only added to object files when the FPU was set to something else as None

 

It seems like IAR 7.30 does not understand the "compatible" option.

 

Can the libraries be patched so that I can use the libraries.

 

Kind regards,

 

 

I try to compile an example project from the new MKW2xD_MCR20A_Connectivity_Software_1.0.0 but linking closes with:


Internal Error: [CoreUtil/General]: Illegal value for Tag_ABI_VFP_args

 

I use IAR 7.30

 

Is this an issue with more people and can I solve it?

 

Kind regard
