Hello All ,



 I compiled a driver module  using cross compiler for MPC8247 , now when
I try to insert the module in to the target  I give me an error like



root@10.0.0.2:/home# insmod linux-kernel-bde.o

Using linux-kernel-bde.o

insmod: unresolved symbol devfs_register

insmod: unresolved symbol vsprintf

insmod: unresolved symbol kmalloc

insmod: unresolved symbol create_proc_entry

insmod: unresolved symbol __get_free_pages

insmod: unresolved symbol __save_flags_ptr

insmod: unresolved symbol ioremap

insmod: unresolved symbol free_irq

insmod: unresolved symbol high_memory

insmod: unresolved symbol devfs_unregister

insmod: unresolved symbol iounmap

insmod: unresolved symbol mem_map

insmod: unresolved symbol simple_strtoul

insmod: unresolved symbol sprintf

insmod: unresolved symbol __restore_flags

Hi Srideep,

 

Can anyone show me how I can overcome below problem?

I have searched mailing list but I can not find any answer for that problem.

 

[test ~]#insmod linux-kernel-bde.o 

Using linux-kernel-bde.o

Using linux-kernel-bde.o

insmod: Warning: kernel-module version mismatch

        linux-kernel-bde.o was compiled for kernel version 2.4.20_dev

        while this kernel is version 2.4.21-pre5

insmod: unresolved symbol devfs_register

insmod: unresolved symbol devfs_unregister

 

Thanks.

William.

I can find the option for /dev filesystem in 2.4.x kernel.
Thanks.

This most likely means you dont have devfs built into your kernel or  
the module for devfs isn't loaded.
