[ts-7000] Driver on 7800

["manu_bourse" <>]

Hi,

 

I would create a driver on Linux Board TS-7800.

 

I have build my driver to another Linux RedHat (2.6.9-5.EL) with the
Source code (linux-2.6.21-ts-src-oct102008.tar.gz).

 

See my driver bellow:

------------------------------------------------------------------------------------------------------

#include <linux/module.h>

#include <linux/init.h>

#include <linux/kernel.h>

 

MODULE_LICENSE("GPL");

 

int gCpt = 0;

 

static int __init Eip_init(void)

{

  gCpt = 100;

   printk(KERN_DEBUG "EIPTIMER Driver \n");   

 return 0;

}

static void __exit Eip_exit(void)

{

    printk(KERN_DEBUG "EIPTIMER exit 2  _module, gCpt = %d\n",gCpt);

}

module_init(Eip_init);

module_exit(Eip_exit);

------------------------------------------------------------------------------------------------------

 

My Makefile is:

------------------------------------------------------------------------------------------------------

obj-m += EipTimer.o

 

EXTRA_FLAGS += -D__KERNEL__ -DMODULE

 

default:

            make -C /home/jybeaugrand/Linux_Board M=$(PWD) modules

 

clean:

            make -C /home/jybeaugrand/Linux_Board M=$(PWD) clean

 

The command to launch the makefile is:

 

 LinuxDriver] make ARCH=arm
CROSS_COMPILE=/usr/local/opt/arm-none-linux-gnueabi/bin/arm-none-linux-gnueabi-

 

The result is "EipTimer.ko".

 

I copy the file on the Linux Board TS-7800.

And I write: 

            insmod EipTimer.ko

 
The lsmod show the driver -> OK, but the "dmesg" doesn't see my printk
"EIPTIMER Driver"  
 

If I remove this driver : rmmod EipTimer

I see the message "EIPTIMER exit 2  _module" !
 
I doesn't understand why I don't see the Eip_init message ? I would
appreciate any help from you.

 

Best Regards
