You know why I recommended U-Boot :-)

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
(like 0x400000 or so).

forget that, to within half a percent, pi seconds is  a  nanocentury.
