Texas Instruments BeagleBoard T2/Linux

The USB-powered Beagle Board is a low-cost, fan-less single board computer based on a OMAP3530 ARM processor.

• over 1,200 Dhrystone MIPS using the superscalar ARM Cortex-A8 at up to 600 MHz
• 256KB L2 cache
• 128MB DDR RAM
• OpenGL ES 2.0 capable 2D/3D graphics accelerator capable of rendering 10 million polygons per second
• HD video capable TMS320C64x+ DSP for digital signal processing at up to 430MHz
• USB powered
• DVI-D / HDMI for connecting digital computer monitors
• MMC+, SD, SDIO interface for memory or wireless connectivity
• S-Video out for connecting NTSC or PAL TV equipment
• stereo audio in and out for a microphone and headphones or speakers

Notes

In contrast to many other embedded boards the BeagleBoard does not come with a classic network interface (e.g. no Ethernet). For network connectivity either a USB implemented Ethernet dongle or a Wi-Fi (WLAN) SD-card could be used.

Due to stability, and reliability problems the initial 2008 boards do not come with the second, EHCI USB 2.0 port soldered to the PCB. It's said that rev. C boards shipping in 2009 will have a functional EHCI USB 2.0 port. At the time of writing the USB OTG port is the only functional USB port and so thus the device can not act as host and device at the same time.

As usual for Imagination Technologies PowerVR based graphics, there is no open source code to drive the 2D/3D acceleartor. There exists only a bare-minimum mode-setting Linux kernel (OMAP) FB driver. Proprietary binary-only libraries are circulated to provide a rather rogue OpenGL ES environment for accelerated 2D/3D.
