VGA Video Capture Driver for GIT kernel 2.6.29

The VGA Video Capture Driver is implemented in a patch for the GIT kernel 2.6.29. It contains mt9t113 sensor driver, as well as the davinci VPFE video capture driver. The demo requires VGA imager board LI-LBCMVGA.

Important notes:

• Network is not working reliably on the Leopard Board, in kernel version 2.6.29. There's a patch available to improve the network performance on this kernel, for more information visit the Applying the DM9000 patch for kernel 2.6.29 page.
• The best way to test the driver is to run file system on an SD CARD.
• The sensor data lines are connected to CCD13 to CCD6, and it outputs YCbCr data.
• To capture YCbCr data correctly, the CCDC is configured to take RAW Bayer format, and it shifts the data 6 bits to the right, then pack it to 8 bits mode. Therefore, data captured in SDRAM is YCbCr format, and it can be fed to IPIPE for further processing, or sent to display driver.
• The mt9v113 sensor driver supports VGA output only.
• The mt9v113 datasheet is not open to public.

Download the files:

• Image Capture Demo Software: demo code that saves image to a file.
• uImage: kernel image binary file.
• VGA Video Capture Driver patch on Linux version 2.6.29
• YUV/RAW image viewer software: free raw_viewer.exe provided by Leopard Imaging. It requires Microsoft .net framework.
• vga_driver_install.txt

To see the steps needed to apply the patch and use the video capture demo, go to vga_driver_install.txt or visit the Using the VGA capture demo for Leopard Board DM355 page. For more information on this demo, visit Leopard Board Support site

IP net cam demo

• Runs on Linux Kernel 2.6.10 (Monta Vista Linux 4.0)
• Requires 5M imager board LI-LBCM5M1 or LI-5M03 to run 720p at 30fps HD DEMO

It requires the following files:

• Linux Kernel & IPNC demo program
• U-boot for Leopard board (source)
• Ramdisk
• U-boot for Leopard board (binary)
• uImage (this is binary file, please, save it without any extension)
