Is there any example of running a module with barebox?

Cheers,
Renaud.

No, currently no example. It's similar to the kernel: enable module
support (depends on experimental), build barebox as usual and do
a make modules afterwards. There currently is no modules_install target,
you have to pick the .ko files manually and transfer them to your board.
Note that you will probably hit some 'undefined' errors, you would have
to add the missing EXPORT_SYMBOLs to some functions.

Hi,

	I'm trying to comunicate some parameters from kernel to a module.
	I define a new function somwhere in kernel and after rebuilding
the version of my function is something like :

c027b7f0 function_R__ver_function (# cat /proc/ksyms | grep function)
(somewhere in *.ver files I can see the correct version)
And if I want to insert my module in kernel I get an error :
func.o: unresolved symbol function (because of the wrong function version)

Something is wrong, but I don't know what ...

You can help me ?

Best Regards
Adrian Stanila

P.S. I'm a newbie in kernel hacking and I don't want to disturb you but
if you can help me ... please answer to my email :)))

If you're using module versions, then you need to do the necessary build
stuff correctly.

In that case you should be reading http://kernelnewbies.org and posting
to kernelnewbies@nl.linux.org

Always read the FAQ before asking questions.  You will find this
question answered in the lkml FAQ which appears at the end of every
mail on lkml.

Module

[Sourav Sen]

Hi,
	I am facing problems in loading a module under 2.2.16. The actual
kernel is 2.2.14 and it loads in it without any trouble, but when I run my 
unmodified kernel 2.2.16(I only patched the kdb patch with it and
configured with all kernel hacking options on) and try to do a insmod, it
says that it could not find the kernel the module was compiled for. I put
the CONFIG_MODVERSIONS on(ie, included modversions.h) also included the
specific version.h file. (I declared the __NO_VERSION__ before including
module.h so that it does not  include version.h). But still it does not
work. Any idea whats going wrong?
