Loading srec imagine problem.

Loading srec imagine problem.

Hello ,

I have now the following cross toolchain
binutils 2.10.1 - egcs.1.0.3a - glibc-2.0.6.

I manage to cross compile the kernel for mips and when I try to load the
srec imagine on the mips I get the following error.

For this srec imagine I used mips-linux-objcopy -O srec vmlinux
srecimagine.

Wouldnt this use the original load address of the vmlinux as the srec
address ? Wouldnt this mean you are probably overwriting your monitor
while loading the srec ? Ususally you would load the image via srec to
a different location with a small copy and run type code in front.

Without a memory map etc one cant help here ...

     Why is it called "common sense" when nobody seems to have any?

I do not know if this is the problem. I made objdump on this srec imagine and
it looks like the sections begin somewhere below 0x80100000 address and for
the srec imagine ( the one that I can load on ) the sections begin after
0x8010000 address. So the problem is here , something with setting the write
address for this srec imagine. Maybe from objcopy ( but I do not think so )
or from linker.
