Ok, if you do an arm-linux-nm on this, find the address of the following symbols,
eg:
10008000 T _start
10013420 D input_data
Find the offset between input_data and _start, ie 0x10013420 - 0x10008000 = 0xb420
Then, use dd to extract the gzipped data from the zImage, eg:
dd if=zImage of=zImg.gz bs=1 skip=46112
Using gunzip, gunzip the resulting zImg.gz file. If the gunzip is successful,
the zImage file contains a valid gzip, else it doesn't.
Try this both with -Ttext and without, however I believe that you will find
in all cases a valid gzip file in there.
I don't believe that there is anything wrong with the binutils, since I'm
now using the same as other people with this problem, and I have none of
these. I believe that the only tool left to consider is egcs (unless you
can prove otherwise).
