Tiny6410 U-Boot fix?

deltaT
Hi all,
just wanted to check if there's already a new version of uboot available
for the tiny/mini6410?

I remember stumbling over a thread where it was said that the current
(1.1.6 / 2011-03) uboot is buggy.

In my version (1.1.6), nothing works except the "q" command and some
console commands.
Formatting, downloading or whatsoever doesn't work, it just displays the
menu again -_-
