SocketCAN Bridge demo based on Nucleo H743ZI platform
|
||
|
|
=====================================================
|
||
|
|
|
||
|
|
This demo showcases host integration for CAN.
|
||
|
|
|
||
|
|
Host requirements
|
||
|
|
-----------------
|
||
|
|
|
||
|
|
On the host side you'll need to create a virtual CAN interface.
|
||
|
|
|
||
|
|
For this, ensure that the ``vcan`` module is loaded::
|
||
|
|
|
||
|
|
# modprobe vcan
|
||
|
|
|
||
|
|
To setup a virtual bus, named ``vcan0``, run the following commands::
|
||
|
|
|
||
|
|
# ip link add dev vcan0 type vcan
|
||
|
|
# ip link set up vcan0
|
||
|
|
|
||
|
|
Running the demo
|
||
|
|
----------------
|
||
|
|
|
||
|
|
With the host prepared, running the script will generate some traffic on the ``vcan0`` interface::
|
||
|
|
|
||
|
|
(monitor) start @scripts/complex/socketcan_bridge/nucleo_h743zi-socketcanbridge.resc
|
||
|
|
|
||
|
|
All packets from ``vcan0`` will be routed to the ``canHub`` object inside Renode,
|
||
|
|
which is a simulated CAN bus with the Nucleo's CAN controller, ``fdcan1``, connected to it.
|
||
|
|
|
||
|
|
You can see the packets using Wireshark or the ``candump`` tool.
|
||
|
|
|
||
|
|
To send a test packet from host to Renode you can use the ``cansend`` tool, e.g.::
|
||
|
|
|
||
|
|
$ cansend vcan0 "123#00FFAA5501020304" # classic CAN frame
|
||
|
|
$ cansend vcan0 "213##F444546474849505152535455" # FD CAN frame
|
||
|
|
|
||
|
|
Note that FD and XL CAN frame routing depends on the host supporting it.
