About this document
This document provides recommendations for new designs based on the P2041. It may also be useful
in debugging newly-designed systems by highlighting those aspects of a design that merit special
attention during initial system start-up.
Each section has a pin termination checklist or a system-level checklist, or sometimes both.
Before you begin
Ensure you are familiar with the following Freescale documents before proceeding:
• P2041 QorIQ Integrated Processor Hardware Specifications (P2041EC)
• P2041 QorIQ Integrated Processor Reference Manual (P2041RM)
• P2041 Chip Errata (P2041CE)
• QorIQ Data Path Acceleration Architecture (DPAA) Reference Manual (DPAARM)
