Hi,

Thank you very much for your help, I have now managed to insert my module.

Small remark, so I used the command ''mknod ...''

to create the special file ( ''/ dev / mydriver''), only I had the following error:

''read only file system''.

So I create the special file on my PC with ubuntu HOST in the directory ''romfs'' and I do a ''make image''.

Looks like it worked, thank you again for your help!

Hello Cédric,

Your driver should be build as a static module (compiled within the kernel) module loader doesn't support thumb relocation.

You can put your driver under ''drivers/xxxx/yourmodule.c'' where xxxx is the driver sub category, and yourmodule.c is your driver module.

Under drivers/xxxx/ update ''Makefile''/''Kconfig'' files to compile the new module.

/*******************************************************/

in Kconfig :

config XXXX_MY_DRIVER

       bool ''Select my driver to be compiled or not''

        depends on XXX_OTHER_MODULE_IF_IT_DEPENDS_ON

       help

         Your module description ......

/*******************************************************/

in Makefile :

obj-$(CONFIG_XXXX_MY_DRIVER)                +=  yourmodule.o

/*******************************************************/

From the kernel configuration menu you can now select your driver to be compiled.

Rebuild the kernel and run it.

Good luck.
