圖2. 快速設(shè)計智能應(yīng)用藍(lán)圖(SABRE)平臺外形圖 This document is the Hardware Reference Manual for the i.MX53 Quick Start board based on the Freescale Semiconductor i.MX53 Applications Processor. This board is fully supported by Freescale Semiconductor. This Manual includes system setup and debugging, and provides detailed information on the overall design and usage of the i.MX53 Quick Start board from a Hardware Systems perspective. The Quick Start Board is an i.MX535 platform designed to showcase many of the most commonly used features of the i.MX535 Applications Processor in a small, low cost package. The MCIMX53-START is an entry level development board and a near perfect subset of its larger sister board, the MCIMX53SMD, which is available as a full, near-form factor tablet. Developers can start working with code on the Quick Start board, and then port it over to the SMD Tablet if additional features are desired. This gives the developer the option of becoming familiar with the i.MX535 Applications Processor before investing a large amount or resources in more specific designs. i.MX53快速入門板主要特性:
