Re: [microblaze-uclinux] insmod: Not configured to support old kernels

[Giulio Mazzoleni <giulio.mazzoleni@xxxxxxxxxxxxxxxxxxxxxxx>]

Hi David,

I would also suggest checking the compiled driver with "/sbin/modinfo
test.ko", just to be sure it was compiled against the right kernel.
modinfo is from the developer machine modutils and should be already in
place.

By the way, I think it may be an issue with my build system, but I had
to change a line in
PetaLinux/tools/linux-i386/microblaze-uclinux-tools/bin/microblaze-uclinux-ld:
- exec $LINKER "$@"
+ exec $LINKER "$@" -melf32microblaze
to be able to compile a kernel module in PetaLinux.

Just my 2 cents suggestion.

Thanks for all your interest and support!
Giulio
