Re: FPU problem urgent

I am not 100% what the problem is, but for a first try, I see some very
strange things in your code. You initialize your FPU inside main, which
looks like a very bad thing to me, because you have some floats in the
stack, some of them even initialized! (i=0). Another side note, you should
initialize it to 0.0, or 0F. I encourage you to read in some book implicit
an explicit variable initialization. Anyway, so the compiler will initialize
a float without you even having your FP unit working yet. Looks like an
exeption fault to me. As I've mentioned in my last email, you should
initialize your FP unit earlier (I do it during processor intialization,
when you initialize your PLL, memory controllers, etc, before your static
data gets initialized)! 

I am not sure how CW works with asm functions (saves registers) and I don't
remember either if r3 is a scratch register or something important. Check
this out, otherwise your fpuaku function might corrupt your r3. (someone
else please help on this one).

Last but not least, it is very unlikely that CW generates bad code. So if
your disasembly looks bad, your are most likely either looking at it in the
wrong way, or you are experiencing memory corruption.
