You need to install the TI DDK version that is compatible with your DM642EVM board version. There are three versions of DM642 EVM board that differ in a number of areas, including the CPU speed and the video decoders used.
- For version 1 DM642 EVM boards, install DDK Version 1.10.
- For versions 2 & 3 DM642 EVM boards, install DDK Version 1.11.
Here is how to identify the board version:
DM642 EVM board versions 1 and 2 are essentially the same except for the CPU clock speed which was upgraded from 600 MHz on version 1 to 720 MHz on version 2.
Versions 1 and 2 use the Phillips SAA7115 video decoders. Version 3 is a redesign with TI TVP51xx video decoders and a CPU clock speed of 720 MHz. Note that version 3 requires updated TI video drivers (included with TI's Device Driver Developer's Kit (DDK)) to match the new decoders.
Here is how you can identify the version number of your board:
Version 1--Original board with 600 MHz DM642, Philips SAA7115 video decoders. ASSY 506840 Rev. D on back of board, 50 MHz oscillator.
Version 2--Original board with 720 MHz DM642, Philips SAA7115 video decoders. ASSY 506840 Rev. D on back of board, 60 MHz oscillator.
Version 3--Revised board with 720 MHz DM642, TI TVP5146/5150 video decoders and HD filters. ASSY 507340 Rev. B on back of board, 60 MHz
oscillator.
The audio.I64 library is included only when you use the DM642 Video ADC block in the model and when the decoder type for the Video ADC block is selected as SAA7115. This set of conditions indicates that you are using the Version 1 board. If the you have a version 2 or 3 board, set the Video ADC block decoder type to TVP5146.
