Device drivers as part of kernel
I am using the iMX25 PDK to which linux-2.6.31 is ported.I have developed parport_arm using GPIO pins.If I build the kernel with lp,parport and parport_arm as modules.
In the pdk, i will give
cat somefile > /dev/lp0 - It is working fine.
If I try to configure parport,parport_arm and lp as part of kernel, I can see /dev/lp0.But when I try I to print ,Its not printing.I think some dependencies are missing for these device drivers.
please suggest me where i am going wrong.
