Configuring CAN/Serial Capes
Various capes (extension boards) are available for the BeagleBone Black in order to extend the range of functions. A cape is plugged in to the expansion slot of the BeagleBone Black and itself provides an additional expansion slot. A BeagleBone Black can be expanded with a maximum of four capes.
This chapter describes the general configuration of a BeagleBone Black which is extended with a CAN cape.
The requirement for extending the cape is kernel version 4.1. The descriptions may vary slightly for other kernel versions.
Tip
You can use the following commands in the command line to determine the kernel version (for example, via an SSH connection):
uname -a
uname -r
