It seems so, that your kernel is corrupted! Check the Kernel and your
bootargs!

You are trying to extract your kernel to the same address which it is
downloaded to (0x30008000).  This will not work, as it will overwrite
itself as you try to extract it.  You need to either a) change your
download address or b) change your load address/entry point.  Solution
(a) is most likely the correct answer.

Well, are you sure? The image is marked as XIP, but I have  to  admit
that  I  don't know what this means on ARM; but there seem to be more
things wrong - image  size  is  706  kB,  which  would  allow  for  a
compressed  2.4 Linux kernel - but AFAIK there was no support for XIP
in 2.4 fro ARM, and  especially  there  cannot  be  any  XIP  from  a
compressed image.

I guess the main problem  is  that  this  is  no  plain  code  but  a
compressed image despite the header information; and if the load / EP
addresses are correct is yet another issue.

Best regards,

Wolfgang Denk
