2 | * Neuros Technologies OSD2 board support | |
3 | * | |
4 | * Modified from original 644X-EVM board support. | |
5 | * 2008 (c) Neuros Technology, LLC. | |

9 | * The Neuros OSD 2.0 is the hardware component of the Neuros Open | |
10 | * Internet Television Platform. Hardware is very close to TI | |
11 | * DM644X-EVM board. It has: | |
12 | * DM6446M02 module with 256MB NAND, 256MB RAM, TLV320AIC32 AIC, | |
13 | * USB, Ethernet, SD/MMC, UART, THS8200, TVP7000 for video. | |
14 | * Additionaly realtime clock, IR remote control receiver, | |
15 | * IR Blaster based on MSP430 (firmware although is different | |
16 | * from used in DM644X-EVM), internal ATA-6 3.5” HDD drive | |
17 | * with PATA interface, two muxed red-green leds. | |
18 | * | |
19 | * For more information please refer to | |
