I am working on a project where we would like to connect 2 cameras and a serial connection (for communication with a PandaBoard). Is the DuoVero able to use USB cameras, or can it only connect via the 2xCSI-2 ports?
We are currently using the Ubuntu Core 12.04.2 build, with TI's Ubuntu-omap4-extras package installed. That being said, if we were to connect the cameras to the USB bus (or the CSI-2 ports), what all needs to be done in order to receive the video/image feeds? Are there other drivers or special kernel modifications that need to be done?
This is my first embedded Linux project so this is fairly new to me, so I'm just trying to figure this all out.
I can answer your questions (and hope you can answer mine)!
The DuoVero is a computer and operates as if it was any other computer. You
can connect USB cameras to it (I am using the DuoVero with a USB2 Point Grey
Chameleon camera). I'm not sure what expansion board you are using although.
I'm using the Gumstix Parlor and have to use a USB Hub for all my
We have Ubuntu Core 12.04 as well (no omap4-extras), and have no problem.
You might want to apt-get install usbutils to get a utility lsusb to tell
you what USB devices are connected. I have had some issues with current
being drawn through the Parlor, so I have made my USB hub powered
externally. You might want to consider this depending how many devices you
would like to use.
On a side note, may I inquire you about your efforts to get the omap4-extras
package installed? Did you use Steve Sakoman's kernel and then installed
omap4-extras? Did you use the kernel from Ubuntu? If you could perhaps tell
me the process you went through to get this installed, that would be great!
