The list here describes common causes of failure found on boards returned to Diamond Systems for repair. This information is provided as a source of advice to help you prevent damaging your Diamond (or any vendor‟s) embedded computer boards. -
Page 4: Introduction
1. INTRODUCTION The CME-Atom is a highly integrated computer-on-module (COM) based on the low power, high performance Intel® Atom processor clocked at up to 1.6GHz. The module is equipped with up to 2GB of soldered-on DDR2 SDRAM and provides interfaces for high-resolution CRTs and LVDS-interfaced LCDs, gigabit Ethernet, SATA drives, USB peripherals, and audio. - Page 5 Note: The COM Express specification is available from the PICMG organization (http://www.picmg.org). The COM Express Tutorial and COM Express Design Guide are available for download from the PICMG organization COM Express website located at: http://www.picmg.org/v2internal/COMExpress.htm CME-Atom User Manual 1.2 www.diamondsystems.com Page 5...

2.3 Bus and Interface Connector Summary The CME-Atom has two 2x110-pin interface connectors, as listed in the tables below which are defined in accordance with the PICMG COM Express Specification. Signal functions relating to all of the module‟s interface connectors are discussed in greater detail in Section 4 of this document. -
Page 10: Getting Started
3. GETTING STARTED This section of the CME-Atom User Manual covers basic hardware setup, power connection, system boot-up, and initial software configuration. First-time CME-Atom users normally receive the product in conjunction with one of Diamond‟s Development Kits, which provide everything needed to ensure rapid application development. -

Linux and Windows operation, and full documentation. 3.2 Preparing the Hardware If it is not already installed on the baseboard, carefully plug the CME-Atom into the baseboard‟s COM Express bus connectors. Place the heatsink or heat-spreader supplied with the CME-Atom on top of the module, carefully positioning it so that its mounting holes line up with those of the module. -
Page 12: Booting The System
Power-up the display, then power-up the system power supply. The CME-Atom module should begin its boot-up sequence immediately, as evidenced by BIOS messages on the connected display. You can use the BIOS Setup utility and install an operating system on the boot drive just as you would on a normal desktop PC. -
