I'm not sure exactly what kind of cameras you want to get working, but if you are looking to get CSI2 cameras going through the ISS, Sergio Aguirre has been working on support. He also works on the media-ctl tool, which is used for configuring the media framework pipeline. The latest versions that I am aware of are here: git://gitorious.org/omap4-v4l2-camera/omap4-v4l2-camera.git I've also added Sergio on the CC list.

My kernel can see the camera OV5650 and set up the pipeline. I am able to grab the raw SGRBG10 data but I'd like to get the ISS to convert this to a more usable UYVY format. Here's what I tried: media-ctl -r media-ctl -l '"OMAP4 ISS CSI2a":1 -> "OMAP4 ISS ISP IPIPEIF":0 [1]' media-ctl -l '"OMAP4 ISS ISP IPIPEIF":1 -> "OMAP4 ISS ISP IPIPEIF output":0 [1]' media-ctl -f '"ov5650 3-0036":0 [SGRBG10 2592x1944]' media-ctl -f '"OMAP4 ISS CSI2a":0 [SGRBG10 2592x1944]' media-ctl -f '"OMAP4 ISS ISP IPIPEIF":0 [SGRBG10 2592x1944]','"OMAP4 ISS ISP IPIPEIF":1 [UYVY 2592x1944]' Sadly, I can't get the IPIPEIF element to take SGRGB10 in and put UYVY out (my reading of the manual implies that this _should_ be possible). I always see this pipeline setup: - entity 5: OMAP4 ISS ISP IPIPEIF (3 pads, 4 links) type V4L2 subdev subtype Unknown device node name /dev/v4l-subdev2 pad0: Input [SGRBG10 2592x1944] <- 'OMAP4 ISS CSI2a':pad1 [ACTIVE] <- 'OMAP4 ISS CSI2b':pad1 [] pad1: Output [SGRBG10 2592x1944] -> 'OMAP4 ISS ISP IPIPEIF output':pad0 [ACTIVE] pad2: Output [SGRBG10 2592x1944] -> 'OMAP4 ISS ISP resizer':pad0 [] Am I missing something?

How can I make this conversion in the ISS? The core problem is that, i haven't published any support for RAW10->YUV conversion, which is part of the IPIPE module (not the IPIPEIF, like you mention). I had some patches, but sadly it is unfinished work. :/ Now, there's a main non-technical problem... I no longer work at TI since end of June this year, and I don't have the right HW setup available anymore. Those sensors were company's asset, and I couldn't keep any. Now, we can make this work with cooperation of someone who has the right setup, and me sharing my patches and some advice on my experience. What do you think? > > Note: if this is not the appropriate place to ask these questions, please > redirect me (hopefully to a useful list :-) As I'm the main person who has been actively developing this, I'm your guy to ask questions :). By the way, this development has been my initiative the whole time, and not an official TI objective, so, to be honest, asking TI for official support won't help much right now.

Tell me how I can help make this happen. I'll be glad to apply patches, figure out bugs, etc, I just need a little help with getting started. I have access to the hardware and it's really important that I make some progress on this soon. Can you share your RAW10->YUV patches and some guidance on how to proceed? I have been able to capture RAW10 data, but often the whole thing just sits there (hangs). Restarting the process sometimes works, sometimes not. Looking at the registers and the actual signals on a scope do not show any difference that we can find. Any ideas what might cause this? Have you seen it as well? Thanks for the help - Please let me know how I can get this working... -- ------------------------------------------------------------ Gary Thomas | Consulting for the MLB Associates | Embedded world ------------------------------------------------------------ ^ permalink raw reply [flat|nested] 9+ messages in thread

That part's good. However, just like before, with either RAW10 or UYVY, the grab process does not start more times than it does (it only starts about 1 out of 10 tries). If I just ^C and try again, it may start, it may not. The single time I was able to get the UYVY capture to work, I got an error after the first frame: # grab-uyvy Device /dev/video3 opened.
