DVP Evaluation Software


This is a short FAQ about DVP Evaluation Software (former XRC software) that comes together with boards such as:






1. What is DVP Evaluation Software?

   It is a software that allows for evaluation of ADI video parts.

   In configuration where evaluation board is connected to PC/Laptop using USB connector.

   Evaluation boards have an USB chip that works effectively as a I2C to USB converter,

   so I2C registers from all devices can be read using software on a PC. See screenshot below.

2. What DVP Evaluation Software is capable of?

   It allows for accessing registers, downloading scripts, reading back data etc.

   Additionally DVP Evaluation Software shows values of registers

   associated with their names (see screenshot). Additional feature that is worth

   mentioning is a fact that it allows for Python scripting. User can write any piece

   of software that reads/writes registers in any algorithmic order (loops,

   condition statements, etc) ; outputting/inputtnig data from files; building GUI

   blocks (with wx python) showing any data and interpretation of user is interested in;

3. What operating systems are supported:

   Windows XP

   Windows 7

4. Notes regarding Windows 7.

   In older version of DVP Evaluation Software - script files and boards files

   are installed in Program Files folder. Windows 7 by default doesn't allow

   application itself to modify own files in those folders, therefore it is

   recommended to run DVP Evaluation Software as an Administrator.

5. How to upload/add new boards into DVP Evaluation Software?

   To add new boards into DVP Evaluation Software you will need:

   a) board specific files

   b) DVP Evaluation Software installed on your PC.

   "Board files" (or board specific files) is a directory structure that contains

   set of specific .xml , script files, and board_info files files.

   .xml file - contains XML description of register maps and registers of device (let say ADV7611)

   script files - is usually a single .txt script file that contains number of scripts to set part

            into particular working mode (e.g. signle script that configures ADV7611 and ADV7511

            on a one board to receive HDMI on ADV7611's side and output it from ADV7511).

            Script files must have following name: [NAME_OF_DEVICE]-VER.X.A.txt

            (Where Name_of_device - e.g. ADV7611, X - major version number; A - minor

            version number that can be ended with letter; there must be no more dots or hyphens

            in name; example correct one is: ADV7611-VER.2.9c.txt)

   board_info.txt file - additional installation file telling DVP Evaluation Software how

            board should be installed (e.g. receiver board).

   Example board files ADV7611:

   >>ADV7611 (folder that contains following):

      ADV7611.xml (file)

      board_info.txt (file)

      >> Script (subfolder, which contains):

           ADV7611-VER.2.9c.txt (script folder).

   To upload new board:

   Place whole board files structure (including top folder e.g. ADV7611) into:

   Where_DVP_Evaluation_Software_is_installed\xml\New Boards\[HERE],



   Where_DVP_Evaluation_Software_is_installed\xml\New Boards\ADV7611

   Run your DVP Evaluation Software and click "Upload boards".

   Note: that in case of Windows 7 you may need administrator priviliges to allow program

   for modification of board files.

6. After powering up board - DVP Evaluation Software shows an I2C error.

   There might be few possible problems:

a. I2C map addresses are not set in your video part:

   Video components by Analog Devices contain number of I2C map

   (such as CP Map, IO Map, HDMI Map and other).  Only main maps (such as

   IO Maps are programmed at start). Therefore when powering up board

   and opening CP Map - you may get error. Go first to Main Map (or IO Map)

   and configure CP Map address to desried (registers to set slave addresses

   are on very bottom of IO Map/Main Map -> between 0xF0 ... 0xFF)

b. Repeater driver running and keeping I2C bus busy

    Some of video boards come with microcontroller that is preloaded with software.

    This software may keep I2C bus busy and not allow your PC to communicate

    with board. Make sure software driver is disabled (SW Enable switch on your board)
