Re: Linking against armlink produced ELF for armv6-m (thumb only) CPU

[Matthew Gretton-Dann <matthew dot gretton-dann at arm dot com>]

Hi,

The root cause of the issue is that the linker is assuming the wrong 
defaults for an object which does not have a .ARM.attributes section.

There is no one particular build attribute causing the error, it is the 
defaults ld assumes.

One workaround may be to strip all the .ARM.attributes sections out of 
the objects before passing them to the linker:
  arm-none-eabi-objcopy -R '.ARM.attributes' tst.o -o tst.stripped.o

Thanks,

Matt
