oh.... well that was bloody timely information I can tell you.

so... err. toolchain options are limited therefore to Linaro <= 2012.04
(as later ones REQUIRE hardfloat to work on buildroot)

I do have one question about that? Isn't that like... really stupid? I thought ARM8,9 LOVED hardfloat... why would they use a softlfoat one?

sigh. (goes off to reconfig buildroot)


YES:
Quote:
Linaro toolchain for the ARM architecture. It uses Linaro
GCC 2012.04 (based on gcc 4.7), Linaro GDB 2012.04 (based on
GDB 7.4), eglibc 2.13. It generates code that runs on all
Cortex-A profile devices, but tuned for the Cortex-A9. The
code generated is Thumb 2, with the softfp calling
convention, and uses the VFPv3-D16 FPU instructions.
And

To use this toolchain, you must disable soft float usage.
got you. thanks
