BeagleBone (White)
To allow BB to identify appropriate pin headers configuration, Click Cape have an onboard EEPROM programmed to make the use of the Cape “plug and play”, just insert the Cape and reboot the BB.

BeagleBone Black
From adoption of Linux kernel 3.x a new method to configure pin headers was introduced, at the boot time an in-kernel utility named “capemgr” dynamically load Device Tree definitions to configure an appropriate pin headers and bus initialization.

As in the case of the White, reading the information stored in the onboard EEPROM, the use of Click Cape is “plug and play” but needs that the user (just one time) put the *.dtbo file (downloadable from here) in /lib/firmware and reboot the system.
