In this post, I presume from the context that you mean the "User data area boot partition" (I.E: The one you can read as part of the rest of the user storage area.)
The eMMC of the K3 has two other, hardware, boot partitions.
The device end (client end, kindle, RAM kernel, whatever you call it) does not have the code to access the eMMC control registers required to access the hardware boot partitions.
Something on one of my many todo lists. Extend the downloaded command processor ("RAM kernel") with some general purpose eMMC utilities.
May never happen, I may die before I get around to it.
