New Camera driver for AM437x

Jan Moravec

Hi TI,

we are trying to connect the camera TAU2 ( http://www.flir.com/cores/display/?id=54717 ) via parallel CMOS protocol to camera interface of Rico Board (http://www.myirtech.com/list.asp?id=510).

The problem is that there is no Linux driver for camera TAU2. So I guess we have to write a new one.

The camera TAU2 image interface should match the interface of processor AM437x VPFE (http://processors.wiki.ti.com/index.php/Linux_Core_VPFE_User%27s_Guide). There is even functional driver for different camera ov2569. The main difference is in communication protocol: TAU2 uses UART, ov2569 uses i2c.

I would like to ask you: What is the relationship between camera driver and VPFE driver? Should we modify the VPFE driver to work with TAU2, or just write a camera driver like the ov2569?

Thank you for answers

Hi Jan,

I have forwarded this to the VPFE experts.

Please just write the camera driver like ov2659. No need to modify VPFE driver.

Thank you for your last answer.

I found following information:

A VPFE instance can only be connected to a single input source at a time. In the case of a decoder if multiple input ports are available, one must be selected before the capture operation can take place.

So is it possible to switch between camera inputs rapidly to get video from 2 cameras? What would be the maximum FPS?

Thank you
