2. Generating the ‘inodes’ (as Superuser)
For VME-CAN2:
cd /dev
mknod --mode=a+rw can0 c 50 0
mknod --mode=a+rw can1 c 50 1
For VME-CAN4 :
cd /dev
mknod --mode=a+rw can0 c 50 0
mknod --mode=a+rw can1 c 50 1
mknod --mode=a+rw can2 c 50 2
mknod --mode=a+rw can3 c 50 3
3. Loading the CAN Driver (as Superuser)
Example for VME-CAN4 (for other boards see table above):
insmod ican4
(3A. Unloading the CAN Driver
)
The CAN driver has to be unloaded, e.g., after an update of the local firmware in order to
reset the processor of the CAN module. The CAN driver of the VME-CAN4, e.g. can be
unloaded by the following command:
rmmod ican4
