The difference between the compressed and uncompressed image is
40 bytes. So i tried to load the image at 0xa0800000 and tried
to give entry point address as 0xa0800040 but then i get
BAD MAGIC ERROR.
Which means there is not proper image at that address
(or rather, that is not the proper start of the image file).
So how do i look up for the proper load address and entry point
As per the CFG_LOAD_ADDR parameter in /include/configs/pxa255idp.h
load address should be 0xa0800000
but how do i figure out,what is my entry point address.
Please help me resolve this error.
