Re: inflate returned FFFFFFFD - what does this error exactly mean ?

You know why I recommended U-Boot :-)

Now I am getting "controlled" failure (during the same decompression as

what does this error exactly mean ?

Most probably it means that the areas where the compressed  image  is
stored   and   to  where  you  copy  the  uncompressed  code  to  are
over-lapping. Try storing the compressed image at  a  higher  address

Best regards,
