Hi,

>happycactus at cammello:~/buildroot> grep SOFT_FLOAT */*/Config.in
>toolchain/external-toolchain/Config.in:config BR2_SOFT_FLOAT

double a;
...
a = 1.40;
a = a / 23;

If the cpu doesn't provide an fpu unit, you must add the soft float emulation
in your kernel config e/o in your toolchain.

Kernel just resolve the illegal instruction using a soft float unit.
