Hi Jerry

I did as you mentioned:

# ppc_82xx-objdump -x zvmlinux | grep _end
00406000 g     O *ABS*  00000000 __pmac_end
00406000 g     O *ABS*  00000000 __setup_end
00406000 g     O *ABS*  00000000 __prep_end

00406000 g     O .data.init     00000000 __vtop_table_end
#
# ppc_82xx-objcopy --set-section-flags=image=contents,alloc,load,readonly,data \
>  --adjust-section-vma=image=0x0040b274 zvmlinux zvmlinux2
BFD: zvmlinux2: warning: allocated section `image' not in segment
#
#

.. but I get this strange warning!

Therefore, the section image somehow doesn't become loadable:

# ppc_82xx-objdump -x zvmlinux2 | more

What's wrong with my image? Do you have an idea?

Thank you
