"Introducing the BeagleBoard-xM

"The BeagleBoard is a pocket-sized reference board containing a Texas Instruments Open Multimedia Application Platform (OMAP) 3 system-on-a-chip (SoC) processor, which includes an ARM Cortex-A8 core, Texas Instruments C64x+ digital signal processor (DSP), and onboard graphics engine, as well as integrated dual data rate (DDR) random-access memory (RAM). The BeagleBoard is an inexpensive platform for hobbyists, academics, and professionals who are learning Linux and small systems. Figure 1 shows the BeagleBoard-xM.

"In a previous developerWorks article, I explored booting Linux on BeagleBoard revision C, which hosts a 600MHz OMAP3530 processor, 256MB RAM, and 256MB NAND flash memory. Revision xM is more robust with a 1GHz OMAP3730 processor and 512MB RAM. It boots from the microSD card with no flash memory and hosts new interfaces, including a DB-9 serial connector, integrated 4-port Universal Serial Bus (USB) hub, and integrated Ethernet port. The BeagleBoard-xM retains many revision C features, including Digital Visual Interface (DVI)-D output, S-video, audio, Joint Test Action Group (JTAG), and a large expansion header."
