Sorry. I have to get used to googlemail first. My former mail doesn't
handle replys in  a proper way.

I recompiled after clean everything. I could see hash.o is inside libcommon.a.
I just add the make lines of hush and libcommon (see below)
I also checked the compile date of the flashed uboot.
So I have no idea what is missed to get it working.
Best regards
Arno
