In future please set your email client to not wrap, or to wrap at 255 columns,
when sending logs.  Also, please paste part of the real log, not a screen scrape of
it.  It is hard to read doubly wrapped logs.

Sounds like you have a compile mismatch.
How'd you compile u-boot?  When sending
logs like this, please include the configure line
for the app that's failing.
The latest ptxdist can link u-boot for softfp, have a look at that.
Also, be aware that printf("%f", 1.0) will fail on arm softfp at the
moment.
