I am trying to build Linux on a Red hat host and then load it onto a target board. My dev nodes are not getting created properly on the target. Specially the keypad device. The device node for keypad /dev/input/event0 gets created in the target, but when I do a cat on the node, it says "no such device".

# ls -al
drwxr-xr-x 2 7069 100 4096 Dec 13 2007 .
drwxr-xr-x 6 7069 100 4096 Dec 13 2007 ..

# pwd
/dev/input
# cat event0
cat: event0: No such device

Please help me as I am new to Linux.
