Implementation of Bus-off attacks

New_controller — Tue, 11 Jun 2024 12:19:50 GMT

Hi everyone,

I'm currently working on a internal project that involves implementing a bus-off attack in hardware, and I need some guidance on a couple of points.

I'm using Arduino and MCP2515 for this experiment. The goal is to create a scenario where two or more devices send frames with the same ID simultaneously on the CAN bus to induce a bus-off scenario.

Questions:

1. How can I configure two or more devices to send frames with the same ID at the same time? Are there any specific register settings or configurations in the CAN controller that I should be aware of to achieve this?

2.What is the tolerance level or time interface between IDs when two devices send frames with the same ID simultaneously? How precisely do the timings need to be synchronized to ensure the frames collide and cause a bus-off condition?

Any relevant configurations or code snippets would be greatly appreciated.

Hi,

I am not sure you are on correct community.

This is S12(X) and Magni V community.

Best regards,

Ladislav
