Testing Your Board
Verifying Picolo U4 H.264 PCI-104 Board Installation
In the /proc folder, a text file named U4H264PCI104Info lists the detected Picolo U4 H.264 PCI-104 boards. For example, if one Picolo U4 H.264 PCI-104 board has been detected, the U4H264PCI104Info text file contains the following line:
CardCount=1Card/0/VFSType=U4H264Card/0/Version=2.0.0.3 Card/0/BoardType=PicoloU4H264Card/0/SerialNumber=U4000012Card/0/PartNumber=00001234-56
Notes
- This file also contains the Virtual File System driver version.
- Before revision 2.0 of the driver, the file was named /proc/UxH264. This file is still available for backward compatibility only.
Checking the Video Signal Presence
The following procedure checks the presence of a valid PAL video signal on the video input 1 of the Picolo U4 H.264 PCI-104 board:
- Browse to the folder/mnt/my_board/visual/source0/
- Open the file config.xml
The file content is displayed as follows:

- A detected video signal is reported by the presence of the VideoPresent XML element. No detected video is reported by the presence of the VideoAbsent XML element.
- A PAL standard video signal is detected on the video input 1 when the DetectedVideoStandard_PAL XML element is present.
To check the presence of other standard video signals, the DetectedVideoStandard_xxxx XML element in the config.xml file is set in accordance with the video signal standard detected (i.e. xxxx = NTSC or CCIR or EIA).
