I’m interested in using the DuoVero in a camera system, but I have a few concerns I need to address.
1.) Is there an estimate on when a Caspa type camera will be available for it? I love the fact that the MIPI/CSI is on the two connectors versus a less than ideal flex cable (at least it’s less than ideal for our application).
2.) Does anyone know the practical length limitation of MIPI/CSI using a shielded twisted pair cable with the correct impendence? My only issue with MIPI is really understanding how far I can drive the signal. In our current solution I use LVDS for about 20inches before it gets converted back into Parallel and then into the DM3730/OMAP3530. The current solution works well aside from the fact I have to use a digital filter to prevent EMI/ESD events from throwing off the ISP/Previewer, and the frame rate limitation by the ISP parallel interface. MIPI is the easiest way to overcome both of those headaches, but I've never seen anyone use it more than a few inches at most. I do have a test fixture setup to test the AR0330’s signal over HDMI cable (for 20inches), but I have no idea how well that will work (don’t have drivers yet). I've only recently managed to even get a working MIPI system (Variscite has one based on an Omnivision sensor, and the Pandaboard finally has one). I assume the Caspa type camera will use the same Omnivision sensor because the drivers are already available for it, but it would be neat if they used something else.
3.) Does the current version of the Ubuntu for the DuoVero have proper power management and heatsinking so it doesn’t scale back the clock when at 100% cpu usage for an extended length of time? Maybe I’m not looking in the right place, but I don’t see any photos of the heat sinking for the DuoVero. I do see where it shows the weight of the available heatsink, but not what it looks like or the specs for it. Whether it’s designed so we can continuously utilize the full 1GHz at 100% CPU utilization. I ask this because one of my goals is to have it work with the PtGrey Chameleon camera. PointGrey has drivers, and instructions on how to get it working on the Pandaboard. It’s only major downside is the limited frame rate, and the fact that its caused every OMAP4 solution I’ve used to scale back the clock even with heatsinking.
4.) Will there be a faster 1.5 GHz version to compete against the Variscite VAR-SOM-OM44? Or is a 1GHz OM4430 as fast as one can reasonable expect from something as small as the gumstix.
