Dear Sam Carter,
Maybe you have not "mknod" , so the /dev/myDevice
could not be found.

======= 2010-01-07 09:31, your
message: 'No such device or address' when writing to device driver=======
Hi all,
I'm trying to write a simple char driver following the
'Linux Device Drivers' book from O' Reilly. My driver appears in /proc/devices
and under lsmod. I've been trying to register the device fops table so I can
read/write to it, however when I try to cat some data to it in /dev/myDevice I
get the error 'No such device or address'.. The device does appear on the list
with ls /dev/.
Can anyone help me find the source of this problem? Thanks
in advance.
Sam
