1 Introduction

In embedded systems, external flash memory is widely used to store bootloaders and application code. Sitara processors such as AM64x, AM62x, AM62P and AM62Dx support multiple serial interfaces such as OSPI and QSPI for connecting external NOR/NAND flash devices. During custom board bring-up using MCU+SDK, users often face challenges while interfacing a new flash device, such as configuring SysConfig parameters, reading device IDs, or enabling PHY mode.

This application note explains how to configure flash parameters using SysConfig, interpret common error logs, and resolve issues during flash identification and PHY enablement.
