Abstract

This application note details the Linux-based configuration of key display interfaces on Sitara™ AM62P processors, including Display Parallel Interface (DPI), Display Serial Interface (DSI), and OpenLDI/LVDS. The AM62P System-on-Chip (SoC) is built with two Display SubSystems (DSS), each containing two Video Ports (VPs), which can be flexibly routed through integrated DSI and OLDI bridges. This document explores the various supported output configurations, demonstrating how to drive up to three displays simultaneously. Furthermore, since the DSS module in related Sitara processors (AM62x, AM62A, AM62L) is a subset of the AM62Ps, mastering the configuration enables engineers to efficiently implement display solutions across the broader Sitara AM6x product line.
