Redeem to Klipper
Klipper, like Redeem, relies on specific communication libraries to run properly on a Replicape-based setup.
There are differences in these libraries and kernel versions, however. If you can reach the Beaglebone's SD card easily, your best bet is to flash a ReFactor image. This means, of course, you'll have to re-set the networking parameters and the passwords to login will have been changed.
