Thanks. Unfortunately, nothing stands out, but I do see a difference
between the output of your linker from mine.
Yours:
Idx Name Size VMA LMA File off Algn
0 .text 00005ef8 00000000 00000000 00010000 2**5
CONTENTS, ALLOC, LOAD, READONLY, CODE
Mine:
Idx Name Size VMA LMA File off Algn
0 .text 00005f00 00000000 00000000 00010000 2**5
CONTENTS, ALLOC, LOAD, READONLY, CODE
That has the effect of moving the addresses of the following
sections in your vmlinux down by 8 bytes. However, I don't think
that's the cause of this - but it does hint at something being
different in binutils in the way sections are processed in the
linker.
Please add to your linker script after the assignment of _edata:
.image_end (NOLOAD) : {
_edata_foo = .;
}
relink the decompressor, and see what value _edata_foo ends up with
compared to _edata? They should be the same, but I suspect using
your linker, they will be different.
Also try adding
BYTE(0);
after the _edata_foo assignment as a separate test, and see whether
that makes any difference - with that you should end up with the
.image_end section in the output image.
