* Neuros Technologies OSD2 board support
|
|
*
|
|
* Modified from original 644X-EVM board support.
|
|
* 2008 (c) Neuros Technology, LLC.
|
|
* 2009 (c) Jorge Luis Zapata Muga <jorgeluis.zapata@gmail.com>

|
|
* The Neuros OSD 2.0 is the hardware component of the Neuros Open
|
|
* Internet Television Platform. Hardware is very close to TI
|
|
* DM644X-EVM board. It has:
|
|
* DM6446M02 module with 256MB NAND, 256MB RAM, TLV320AIC32 AIC,
|
|
* USB, Ethernet, SD/MMC, UART, THS8200, TVP7000 for video.
|
|
* Additionally realtime clock, IR remote control receiver,
|
|
* IR Blaster based on MSP430 (firmware although is different
|
|
* from used in DM644X-EVM), internal ATA-6 3.5” HDD drive
|
|
* with PATA interface, two muxed red-green leds.
|
|
*
|
