Yes I have the device node. Besides, calling 'fbset' prior to copy operation
works as expected. However, after copy operation device node is overwritten:
root@jd:~# ls -l /dev/fb*
-rw-r--r-- 1 root root 48766976 Jan 1 00:00 /dev/fb0
crw------- 1 root root 29, 1 Jan 1 00:00 /dev/fb1
crw------- 1 root root 29, 2 Jan 1 00:00 /dev/fb2
crw------- 1 root root 29, 3 Jan 1 00:00 /dev/fb3
How can this be possible?
