Introduction

BeagleBoard came out with a new iteration called PocketBeagle in late september 2017. The new Beagle is minimalistic in nature, consisting primarily of an SD Card Reader, a Micro USB Interface, and the Octavo Systems OSD3358 1GHz ARM® Cortex-A8 System-in-Package (SIP).
The getting started page for the BeagleBoard truly gets you going quick with Linux. However, those of us looking to learn embedded systems, are left high and dry. The resources on uses of the PocketBeagle/BeagleBoard for "bare metal" programming are much fewer in number than those for getting started with Linux.
When I bought the PocketBeagle, it was still very new. There were few resources online for "bare metal" booting/programming. This gist will hopefully document some of the problems I encountered while learning how to boot the PocketBeagle into my own code.

The Manual

The manual for the AM335x is 5000+

	local path = vim.split(package.path, ";")
