How to Boot to a Shell with Processor SDK Linux for Sitara Processors

The single shell boot is about bypassing a full user space initialization. Booting to a single shell or thread allows a minimal environment application setup from which any impact from user space on performance issues can be isolated. This technique is a quick alternative, as it uses the out-of-box components of Texas Instruments’ Processor SDK Linux without having to configure and build a utility such as BusyBox. This video demonstrates how to change the kernel user initialization to boot to a shell or single thread using Processor SDK Linux on SItara AM335x, AM437x, and AM57x embedded processors.
