Hi,
Thanks a lot everybody, the "-m68000" was missing and require!

What CPU are you running on?

That MULS.L instruction is definitely wrong. The source effective
address mode specified, is not supported in the longword variant of MULS.
Is it just me, or does that whole disassembly look strange?

instruction is causing your illegal instruction trap.
I would suspect that the CPU you are running does not support
multiplication instructions? You can look into the gcc man page to find
out if there are any options you can p
Hi
Ok I do that:
/opt/m68k-uclinux-tools-20060615/bin/m68k-uclinux-objdump -D xx.o
ucAsserv.o: file format elf32-m68k
Disassembly of section .text:
:

Hi,
try to use "objdump -D xx.o"
You should see the disassembled section of module_init.

Hi Stéphane,
can you also generate an objdump of the module and post it?

Hi Stéphane,
looks like you are compiling your code with compiler flags that generate
instructions that the processor does not support. That's why you see the
illegal instruction trap.
The reason that it all works if the variables are local is probably that
you also use an optimization flag
Hi,
I have a bug that I can be resume as:
