7 Summary

This application note provides a practical debug reference for developers integrating custom xSPI flash devices with TI Sitara processors using the MCU+ SDK. This document outlines systematic methods to diagnose and resolve boot failures, flash read/write/erase issues, and overall device bring-up challenges. Step-by-step checks, configuration guidelines, and validation tips are included to help engineers quickly isolate the root causes and accelerate system bring-up on custom DUTs. By consolidating common failure scenarios and proven debug workflows, this guide aims to reduce integration effort and enable reliable operation of custom NOR or NAND flashes.
