Hi Malay,

 

Erase or rename the ./ltib/rpm/BUILD/hello-mod-1.2 folder and let LTIB build and install the complete module into the rootfs (just in case something was edited).

Use NFS to mount the root fs to your board, then try installing and removing the module.

 

address@hidden /]# cd /lib/modules/2.6.34/misc/

address@hidden misc]# ls

modexample.ko

address@hidden misc]# modprobe -v modexample

Loading module modexample

Using /lib/modules/2.6.34/misc/modexample.ko

say hello

address@hidden misc]# lsmod modexample.ko

Module                  Size  Used by    Not tainted

modexample 603 0 - Live 0xbf018000

address@hidden misc]# rmmod modexample.ko

wave goodbye

address@hidden misc]#

 

My kernel was built using gcc-4.1.2

Linux version 2.6.34 (address@hidden) (gcc version 4.1.2) #61 PREEMPT

 

You can always try insmod –f to force load the module (good luck). You can also try running modinfo on the module on your host machine to get the module versioning info.

Mine is below..

address@hidden misc]$ modinfo modexample.ko

filename:       modexample.ko

description:    This is a very simple example

author:         Stuart Hughes

license:        GPL

depends:       

vermagic:       2.6.34 preempt mod_unload ARMv5

address@hidden misc]$

 

thanks,

Kevin

Subject: [Ltib] i need some help..pls

 

Hi Everybody,

Though i am new to his forum i have been receiving help constantly from you all. Thanks a lot. But i need a little more favor.

I am simply trying to build hello_mod example and run it on my PHY3250 but every time i use insmod at directory misc, it shows me the error "cannot insert 'modexample.ko': invalid module format".
I have followed all the steps given in README file inside the hello module folder. Also i have selected the option of 'Leave the sources after building'. I have tried this module on both 2.6.27 and 2.6.34 kernel, but cannot find out what the real problem is. So please help me find the solution because i am stuck on it for a couple of days now.

I really appreciate your help.

Thanks,
Malay
