9 Summary

By reducing the number of enabled peripherals and reducing their functionality, a minimal configuration can be created for an SoC as an initial test for bringing up a custom board. This application note aims to ease the process of board bring up by outlining a step-by-step process to use the minimal configuration as a starting point to setup a custom board configuration. The minimal configuration streamlines this process and reduces the time of the initial bring up process from days or weeks to hours.
