: VxWorks bootloader PowerQUICC II, Booting the kernel
Ruedi:
Any luck? Jon Diekema (a coworker) solved the problem for us with a
Makefile patch. For details, see the summary of the May messages,
which includes Jon's proposed patch:

Hi Jon Gerald
Thanx for the patches. The kernel compiles now well and even the download
to the SBC8260 seems to work. It downloads 2 sections, perfect.

After having copied parts of embed_config.c to my kernel I get:

Starting at 0x40...

Want to try an experiment that I have been intending to try but haven't
gotten around to? The following is a message detailing my theory that
objcopy can fix up the .image section so that the vxWorks loader _will_
load it. In fact, it may already load it... but at location 0x
Hi Jerry
I did as you mentioned:
# ppc_82xx-objdump -x zvmlinux | grep _end

00406000 g O *ABS* __setup_end

Hi,
I try to boot the Linux kernel on a SBC8260 evaluation board using
the VxWorks bootloader.
In order to be able to load the whole kernel at address 0x90,
I had to modify the ELF header of the zImage file. I basically changed
the length and the start address.
Question:
1. Why is the

Somewhere (and you can look through the archives as well as I can :-),
I posted a program that will hack a zImage so the VxWorks boot loader
will properly load and start
