Dear Sam Carter, Maybe you have not "mknod" , so the /dev/myDevice could not be found.
Sincerely yours, chiachen [email protected] 2010-01-08 ======= 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 = = = = = = = = = = = = = = = = = = = =
