2009-05-06 09:35:06     Problem with the simple driver.

I wrote a simple driver, as mentioned in the driver development in the docs. I am using uClinux-dist-2008R1.5-RC3.

 

I wrote an application to open and close the driver. Everything got built properly. I used mknod to create the device. The application ran with its printf messages and no error, but I didnt see the kernel messages of printk in the var/log/messages file.

 

Further, I could not see the device initialization in the kernel boot log. The driver has been built into the kernel and is not a module. Have I done some mistake? How else can I know that the driver APIs were indeed executed?
