This may be a stupid question, but is that setting somewhere in the
buildroot toolchain config, in the kernel config, or somewhere else
entirely? I've looked for it, but I can't seem to find it.
I'm pretty sure the Cirrus Labs cross toolchain uses software floating
point, because in the guide for setting it up, you have to run this
command:
$ sudo mkdir -p /opt/buildroot/toolchain_build_arm_nofpu/ccache-2.4/cache
I thought that was pretty funny when I noticed it. I may be
misinterpretting that, because I'm pretty sure the EDB9302 does have a
FPU, but it may be something wierd about the Qwerk, or I may just be
an idiot. That instruction is found at
http://terk.svn.sourceforge.net/viewvc/terk/embed/trunk/share/docs/QwerkDevelopmentGuide.html#SettingUpTheARMCompiler
