Introduction

This document describes how to connect the QorIQ
LS1021A Tower System Module (TWR-LS1021A-PB) board
and verify its basic operations such as the switches,
connectors, jumpers, push buttons and LED settings, and the
instructions for connecting the peripheral devices.
It is assumed that you are familiar with the LS1021A device
and the content of the TWR-LS1021A Reference Manual
(document TWR-LS1021ARM).
The prototype part number of the LS1021A tower board
system is X-TWR-LS1021A-PB and the production part
number is TWR-LS1021A-PB.
The figures listed below show the main features of the
secondary and primary sides of the TWR-LS1021A-PB
board.
