Devkit8500D/A Board Overview

Embest DevKit8500D Evaluation Board takes full features of the 1GHz Texas Instruments' DM3730 ARM Cortex-A8 DaVinci™ digital media processor and supports up to 512MByte DDR SDRAM and 512MByte NAND Flash as well as a reserved iNAND design to expand the flash storage capabilities. The board has exposed many other hardware interfaces including serial ports, LCD/TSP, DVI-D, S-Video, Ethernet, USB, TF, keyboard, camera, SPI, I2C and JTAG. The board is able to support for Linux 2.6.32 and WinCE 6.0 operating systems. It has two methods to boot Linux and WinCE systems from either TF card or NAND flash. Besides, it is provided with Android 2.2 demo with driver source code. Embest gives instructions on how to boot Android demo image from NAND flash with TF card.

The board supports using XDS100v2 USB JTAG Emulator for debugging which is available from Embest. Embest also offers 4.3-inch or 7-inch LCD with touch screen and various modules for options including VGA, WiFi, Analog Camera, GPS, GPRS, 3G and Digital Camera modules which greatly extends the functions of the board and would be flexible for customer selection to meet their own needs.

The TI's DM3730 processor is pin-to-pin compatible with TI's AM3715 processor, Embest also supplies the board with the AM3715 CPU and this board is called DevKit8500A.
