Many thanks for the link, but now I've got other strange errors during u-boot compile:

I use following precompiled toolchain from marvell:

Do you know how I can solve this problem?
(I've read the two given mail threads but found no hint to this problem, so maybe my toolchain is broken?)

Many thanks, Dieter
