CANBUS driver for native_posix board #21
Conversation
This initial version supports SocketCAN. The driver passes CANBUS data between Linux vcan virtual CAN driver and Zephyr. You also need to use can-setup.sh script from the net-tools project in order to make communication work with Linux vcan driver. Signed-off-by: Jukka Rissanen <[email protected]>

Hello, I'm trying to work on the native_posix board with can bus lately and came across your pull request zephyrproject-rtos#14196 in zephyr repo. I was wondering if you still have any plan to merge this feature into the upstream or if you have any suggestions on how to make use of this feature with more recent zephyr releases. Thank you very much! |

This was an experiment but I did not had time to finalize it. I am fine if you want to continue this work, currently I do not have plans to continue with this PR. |

Just for anyone who might be interested. I rebased jukkar's work to v2.4-branch and updated the code to make 2 vcan work with the native_posix board. I'm planning to use it in our project for a while in case further adjustments are required. Hopefully, a pull request to the latest master can be made sometime later. Thanks again for jukkar's work. The code can be found here: https://github.com/westonrobot/zephyr/tree/can_native_posix Two additional commits made in addition to the existing 2 commits listed here. |
Thanks, it would be great if you can create a PR for this. |

I am now able to receive and send CAN packets in Zephyr. The Linux vcan virtual interface is the peer in this case. My earlier problems were because filters were not set properly. Currently this only supports Socket-CAN interface in Zephyr, we can add support for Zephyr native API later.
In Linux one can use cansend to send CAN packets like this:
./cansend zcan 001#11.2233.44556677.88
To receive CAN packets do this:
./candump zcan,1:1
The candump and cansend are part of the can-utils package https://github.com/linux-can/can-utils
You also need the can-setup.sh script from Zephyr net-tools repo, I will send new version for it shortly.
