Video capture driver for TMS320DM6446

Sakshar

Hello,

I have downloaded the TI DM644x 1.0.0 BSP Experimental from QNx site which includes a graphics display driver.

Can anyone provide me with video capture driver sources  to help me understand the framework and architecture of a QNX 
video capture driver and later develop the same for DM6446?

Thanks & Regards,
Sakshar

    Sakshar,

    QNX OS is supported thru QNX. I am not sure if anyone from QNX is active in this forum, but your best bet would be to contact them.

    You can probably write a simple driver (sort of character driver on linux) on your platform to read the data from device and verify the CCDC configuration. Seems you will have to write a framegrabber from scratch on your platform.

    Unfortunately as Juan mentioned we do not provide support for QNX directly from TI, and so this is probably something you would have to ask them. If you are looking for some driver code that may serve as an example for developing a QNX video capture driver than if you install the DVSDK software included with the DVEVM board you can find some capture driver sources within your lsp\drivers\media\video\davinci. Of course these drivers are for Linux and would likely take significant porting effort to work within QNX.
