CAN Bus

Introduction

This article shows how to set up a CAN network between two boards. This assumes you are working with a product which supports CAN such as EDM1-FAIRY (with EDM1-IMX6), or PICO-NYMPH (with PICO-IMX6, PICO-IMX7, or PICO-IMX6UL/ULL).

Board connections

Set up two boards so that they can exchange CAN information.

Set up CAN on both boards

Initialize and bring up the CAN interface on both boards.

# ip link set can0 up type can bitrate 125000

On board A, start candump in order to show any received CAN data;

# candump can0

On board B, send some data:

# cansend can0 500#1E.10.10
