For anyone who wants to use a Debian based image for Replicape,

For anyone who wants to use a Debian based image for Replicape, you need to download and compile the device tree:

https://bitbucket.org/intelligentagent/replicape/src/efa48a03b533f45cc241543f255e86edafde8122/Device_tree/3.8/?at=Rev-A4

Place it in /lib/firmware/

compile the DT with:
dtc -O dtb -o BB-BONE-REPLICAP-0A4A.dtbo -b 0 -@ BB-BONE-REPLICAP-0A4A.dts

If you want to use Redeem, you also need tty0tty: https://github.com/freemed/tty0tty

Thanks to @James_Armstrong for finding this out!

A further note for the device tree on debian. If you are still having issues after doing the above, as I did, have a look at:

http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Loading_custom_capes

In brief add “CAPE=BB-BONE-REPLICAP:0A4A” (without the “”) to /etc/default/capemgr. Note the : between the cape name and the version. Otherwise it will try to load version 00A0.
