 Thanks for all the suggestions, but nothing seems to have worked so far.

 It looks like X picks up all sorts of configuration settings
 automatically, since xorg.conf is essentially full of 'default internal
 device' options.  What I can't figure out is how it decides on the
 requested resolution.

 The defaults, with omapfb.rotate=1 in bootargs, result in omapfb
 selecting a virtual resolution of 640x480, but Xorg on boot still tries,
 based on dmesg, to get a 480x640 overlay somehow (at least that's what
 my interpretation of the situation is).  I've tried adding a screen
 subsection to xorg.confg, with virtual 640 480 - no effect.  I've tried
 adding in a modeline for 640x480, no effect.  I tried rebuilding
 Angstrom with a few extra lines in /conf/machine/omap3evm.conf
 (MACHINE_DISPLAY_WIDTH_PIXELS=640, etc), with no effect.

 Does anyone know exactly how Xorg autoconfigures the default panel in
 this sort of a situation?  My current guess is that it's getting 480x640
 from some panel driver somewhere, but I haven't been able to find the
 source.

 For compleness, I've attached the Xorg log, xorg.conf, and the kernel
 log when I try to boot up Xorg (just Xorg, no gpe anything).
 
   
 check the settings for fb0, fb1 and fb2 with fbset.

 FB2 is suspicious, since that's what Xorg uses, I believe.  Attempting
 to set it to something like fb0 and fb1 with:
 fbset -fb /dev/fb2 -g 640 480 640 480 16 -t 52083 1 28 1 1 2 1
 made no difference to Xorg, however.  I tried upping the amount of
 memory allocated to fb2 (I'd forgotten to give it any on the bootargs),
 with no luck.  So fb0 and fb1 are getting defaults from somewhere, but
 fb2 isn't.

 Bootargs currently:
 mem=128M console=ttyS0,115200n8 noinitrd rw root=/dev/mmcblk0p2
 rootfstype=ext2 rootwait omapfb.rotate=1 omapfb.vrfb=y omapfb.debug=y
 omapdss.debug=y vram=32M omapfb.vram=0:8M,1:8M,2:8M

 Thanks for the suggestion!
   

Just in case it would be of use to others later, I did finally find a
resolution to this problem.  The short story is that the current
xf86-video-omafb driver can't handle VRFB rotation, even if it's defined
on the kernel command line, because the driver assumes that the output
framebuffer is contiguous, which is very much not true with VRFB. 
There's also a problem with the order in which it reads and writes
framebuffer parameters, because with the omapfb driver, the frame buffer
fixed info will have to be reread after changing rotation settings or
pixel type, as the stride can change. 

I've hacked up enough of the xf86-video-omapfb driver to get X running
in the proper orientation with VRFB and rotation defined on the kernel
command line, on the OMAP3 EVM (so X runs at 640x480 on the built-in
480x640 LCD).  I haven't gotten the XV extension part of the driver
working right yet.  If anyone wants the ugly results, I'm happy to
share, but I doubt I'll have time to clean them up anytime soon.

Unless you're using an OMAP-based ARM processor, this is probably not
the right list to be asking this.  You're also not giving sufficient
information for anyone to help you much - what processor and what
hardware platform are you compiling for?

In any case, have you run the proper defconfig for your board - see, for
example, the discussion below:

Have you seen this post on N95 camera using linux by Stanford Team -
http://news.cnet.com/8301-17938_105-10345557-1.html

Is this running on OMAP?--



The board in the youtube video looks a lot like the omap3evm, so I 
guess it's safe to say it's omap3 based.

I'm one of the graduate students at Stanford working on this project.

Yes, we're using an OMAP3 EVM (needed the camera interface pins) 
connected to a small custom daughtercard that interfaces to an Elphel 
10338 camera tile, with an Aptina MT9P031 on it.  Plus a bunch of other 
off-the-shelf hardware, but the OMAP3 is at the heart of it.

Re: Problems configuring OMAP35x ISP driver

2009-07-14 Thread Eino-Ville Talvala

Zach,

We've gotten a Aptina MT9P031 driver working with the latest ISP 
patchset, both with YUV and RAW data.
I don't know what the problem might be with YUYV data - we get useful 
YUYV data without any changes to the ISP defaults.
However, to request RAW data, that simply uses the CCDC and bypasses all 
the processing in the ISP, request the pixelformat of 
V4L2_PIX_FMT_SGRBG10.  This will give you two bytes per pixel, at least 
in our case (although we have a 12-bit sensor cut down to 10 bits), so 
be prepared to throw out every other byte.


Hope this helps,

Hello Sergio,

I spoke with you earlier about using the ISP and omap34xxcam drivers with a 
micron mt9d111 SOC sensor.  I have since been able to take pictures, but the 
sensor data is not making it through the ISP data-path correctly.  I know the 
problem is in the ISP data-path because I am configuring the sensor the exact 
same way as I have been on my working PXA system.  I am expecting 4:2:2 packed 
YUV data, but all of the U and V data is no more than 2 bits where it should be 
8.  I know the ISP has a lot of capabilities, but all I want to use it for is 
grabbing 8-bit data from my sensor and putting it in a buffer untouched using 
the CCDC interface (and of course clocking and timing).  What are the key steps 
to take to get this type of configuration?

Other Questions:

Is there any processing done on YUV data in the ISP driver by default that I am 
missing?
Has any one else experienced similar problems while adding new sensor support?

Any help here would be greatly appreciated.

Thank you,

Zach LeRoy

bitsperlong.h missing in asm-arm?

2009-07-14 Thread Eino-Ville Talvala

Hi,

I'm not at all familiar with the way the asm-* include directories are 
handled, but with the current linux-omap tree, I'm getting a user-space 
compilation error with the CodeSourcery 2009q1 release:


In file included from 
/CodeSourcery/arm-gcc-2009q1/bin/../arm-none-linux-gnueabi/libc/usr/include/asm/types.h:
linux-omap-2.6/include/asm-generic/int-ll64.h:11:29: error: 
asm/bitsperlong.h: No such file or directory


It doesn't look like just a CodeSourcery issue, since the missing 
reference is actually in asm-generic/int-ll64.h.


Am I doing something incorrect, or is something missing in 
include/asm-arm  ?


Thanks,
