Hi, I develop kernel module from c code given in mini2440 kernel/driver/char folder. I got .ko file for that kernel program in host pc system. Also I create object file for user space application. Both of them I transfer to mini2440 board through serial port. But when I give insmod command or modprobe command for .ko file (kernel module) it gives error "could not find kernel module". I use mknod command for creating special char device in host pc, but I wan'nt able to transfer it mini2440 board. Also I don't know where & when I use mknod command? Please explain me the procedure of inserting kernel module and execution of the program. Thanking in advance, Rahul.
