AM3352: Multiple cameras with QuickLogic CSSP

Louie

Part Number: AM3352

I am working to try and connect more than one camera to the AM335x. I have found a solution from QuickLogic which connects their CSSP to TI's AM335x. However, I have also noticed that it does this through the single 16bit GPMC. Is there any possible way to connect a second camera working simultaneous but independent of the first camera? If so how will this affect the performance of the AM335x?

With the QuickLogic solution I don't think this will be possible, as it takes almost the entire GPMC bandwidth.

And if I am not mistaken, without Quicklogic's CSSP, it will not be possible to interface with even 1 camera correct? It looks like CSSP by Quicklogic for Camera interfacing does all of the heavy lifting and then writes the data into the memory of the TI AM335x.

AM335x devices have no video inputs. It's either the Quicklogic solution or USB cameras.

In my product I am using one CSSP for finger print sensor. But now I have to connect sensor +camera. Can I connect two cssp with AM335x. Does driver supports? with different chip gpmc chip select. What about performance? At a time only one will work and both camera and senor with QVGA with 30FPS.GMPC can work 100 MHz. I am thinking with two cssp interface with AM335x. I don't about driver supports or not and also configuration dual CSSP.
