Right. Small changes in the source image (which is not a linux kernel)
can lead to a corrupted image. lzop under linux can decompress the image
successfully. I also checked if it is possible to compress the image and
make an u-boot image out of the compressed data under linux. This also
worked without problems but when decompressing that image the error is
the same.
lzo1x_decompress_safe from the current linux kernel is the same as that
one used in u-boot.
Any ideas?
