3. Work on Linux

3.1 Driver and conﬁguration

Mainline Linux has supported the Korlan USB2CAN converter since version 3.9. It works with Linux

distributions like Ubuntu and Debian with no additional driver installation. For Raspbian, the driver must be

built manually. Instruction on building CAN driver for Raspbian can be found on 8devices WIKI pages.

https://www.8devices.com/wiki/korlan:compile-raspberry

Recommended Linux distributions:

•

Ubuntu 18.04 or later

•

Debian 8 (Jessie) or later

•

Raspbian Bullseye

You can verify if Korlan USB2CAN device is recognized by the system and drivers loaded correctly

using the usb-devices command. In the output, you will see your device:

usb-devices

If you use several Korlan USB2CAN devices, you will see all of them in USB-devices output with diﬀerent

SeriaNumber values. The ﬁrst device in the output will correspond to the can0 socketcan interface, the

second - can1, etc.

If the driver is loaded correctly, the CAN interface should be seen by issuing the

ip link show

4: can0: <NOARP,ECHO> mtu 16 qdisc noop state DOWN mode DEFAULT group default qlen 10

link/can

Set can0 interface speed to 125 Kbps:

sudo ip link set can0 up type can bitrate 125000 sample-point 0.875

Bring the can0 interface to UP state (INFO LED lights on, STAT LED lights oﬀ):

sudo ip link set can0 up

To bring down the interface (STAT LED lights up, INFO LED lights oﬀ):

sudo ip link set can0 down

To get more information about conﬁguration options type:

sudo ip link set can0 type can help
