|which CSI-2 MIPI cameras are supported?||1||13:26, 9 July 2014|
At the recommendation of this wiki, I purchased a Logitech C615 USB web cam to use with my NVIDIA TK1. My TK1 has Ubuntu 14.04.1 LTS
The camera is capable of 1920x1080, which I have verified using Cheese, as well as: sudo apt-get install luvcview luvcview -d /dev/video0 -L
However, when I run my Python code using OpenCV, the most I can get is 800 x 448. I've tried using the embedded OpenCV that comes with L4T (2.4.13), but several websites specifically indicate that the resolution is fixed at 640 x 480 and that since Feb 1, 2016 NVIDIA is still "working on a fix". https://devtalk.nvidia.com/default/topic/913233/jetson-tk1/-opencv4tegra-changing-camera-resolution-solved-/
Next, I tried a native compile of OpenCV (2.4.8) but I still can't get higher resolutions. http://elinux.org/Jetson/Installing_OpenCV
I tried enabling USB 3.0, but that didn't make a difference. I bought a USB 3.0 hub <-- no luck either. I also tried adding usbcore.usbfs_memory_mb=1000 to the end of extlinux.conf <-- no luck. I also tried adding vmalloc=384M to the end of extlinux.conf <-- no luck. I also tried patching lib4vl as described at this site <-- no luck! https://www.e-consystems.com/Articles/Camera/opencv-jetson-using-13MP-MIPI-camera.asp
I'm running out of options. Has anyone figured out a way to get max resolution out of a USB webcam plugged into the TK1 so that it can be used with Python / OpenCV? I'm a bit disappointed that NVIDIA has all the hype of being the "go-to" platform for computer vision, yet a simple plug-and-play webcam doesn't work right out of the box.
Thanks in advance for your help!

Sorry to undo your edit, but it looks like while doing your 1 small change, you removed all the changes I did in a previous edit a few days ago. So I undone your edit yesterday to bring back all of my changes (eg: adding many photos to the page). If you look at "http://elinux.org/index.php?title=Jetson/Cameras&action=history", your "minor" edit removed 516 characters, even if you only wanted to make a minor edit. But it looks like it is all fixed now, it currently has my 516 characters of changes as well as your 8 characters of changes so it is good now :-)
Please could we have a list of supported cameras? with links to suppliers would be handy...
I've bought into a few boards over the years, which had CSI-2 MIPI connectors, but no cameras were supported.
it seems clear that currently not one CSI-mipi camera is known to work with Jetson,
Hi, I've asked people at NVIDIA if anyone has used a CSI camera yet on Jetson TK1. I know we have used various CSI MIPI cameras with the chip (Tegra K1) since that is what we having been using for our Tegra K1 based smartphones, tablets and automotive systems. But I'll check about Jetson TK1 specifically.
