I am currently working on my soc-camera patch queue, which I shall clean up, complete and push upstream. Then, on top of it, I'll update the mx3-camera driver. My current version contains a few improvements and fixes over the original version. You should be able to start with the original version too, but if you can, maybe it is better to wait a few days for an updated version. > I would need USB (both host and otg) too (and why not SDHC storage, but this > is less needed for now), it would help my development flow a lot.

I used Bayer, as this is the only format, that mt9t031 can produce. Answering your question from another email, you can use gstreamer, it has a bayer plugin. You probably will get funny colours, because the start pixel is wrong, you could use my patch for gstreamer from here http://bugzilla.gnome.org/show_bug.cgi?id=571976 and then specify on gst-launch command line which starting pixel you want. E.g., my command line looked like gst-launch v4l2src ! video/x-raw-bayed,width=240,height=320 ! \ bayer2rgb start-pixel=green_red ! ffmpegcolorspace ! fbdevsink where the "start-pixel=green_red" parameter is provided by the aforementioned patch. You can also view Bayer images as monochrome, they will look checked, but unless you have very special colour patterns, images should be recognisable. > > I am using branch "mxc-devel" from > > git://git.pengutronix.de/git/imx/linux-2.6 > > > > I am trying to use your patches from > > http://gross-embedded.homelinux.org/~lyakh/i.MX31-20090124/: > > 0001-plat-mxc-define-CONSISTENT_DMA_SIZE-to-8M-needed.patch > > 0002-soc-camera-camera-host-driver-for-i.MX3x-SoCs.patch > > 0003-soc-camera-board-bindings-for-camera-host-driver-fo.patch > > ... as apparently everything needed is already present on that branch, since > > you submitted your latest IPU & IDAC DMA patches to the Linux ARM kernel > > list. > > > > However, this mx3_camera implementation does not fit the IPU/IDMA API > > present in the aforementioned tree, and before asuming the required > > rewritting effort I must ask: > > > > Am I using the right tree, branch and patches for the task? Sorry, I am afraid, you'll have to wait. I only have 24 hours a day...
