[U-Boot] Toradex Colibri, PXA-270 (ARM)

2012-01-23 Thread Daniel Mack 

Hello,

i recently stumbled upon a compile-error which appears after trying to 
compile via


/./MAKEALL --arch arm --cpu pxa --vendor toradex/

, it appears U-Boot uses software-FP whereas the native XScale-libs use 
hardware-FP, see for yourself please :


/[dmack@Blizzard ~/workspace/u-boot]$ ./MAKEALL --arch arm --cpu pxa --vendor 
toradex/

Is there a solution for this, am i missing something?

This is a tool chain problem.  You should get one that supports
soft-FP, especially on processors that don;t have a FPU in the first
place.

GCC 3.4 has always been (in)famous for causing issues, especially on
ARM. And it is so old that you can consider it unsupported.

 Is there a solution for this, am i missing something?

I guess you did not bother to check the mailing list archives?  You
should.

Best regards,
