Overview

---

This snippet allows to configure Controller Area Network (CAN) samples with Linux SocketCAN support on :zephyr:board:native_sim.

By default, the native simulator expects a SocketCAN network device called zcan0 (specified in :zephyr_file:boards/native/native_sim/native_sim.dts). This name can be added as an alternative name for an existing SocketCAN network device (here, a newly created virtual CAN network device vcan0) using a command like the following:

.. code-block:: console

sudo modprobe vcan sudo ip link add dev vcan0 type vcan sudo ip link property add dev vcan0 altname zcan0

The SocketCAN device must be configured and brought up before running the native simulator:

.. code-block:: console

sudo ip link set vcan0 up
