Greetings! I've been working for a while now on capturing images from the
LI-5M03 without much luck. I've tried a few different approaches:1. Tried building kernel version 3.7 from BB's github. Applied patches and
used the beagleboard defconfig included from github. The kernel worked (as
it loaded correctly), and the device was apparently available in video0, but
image capturing was not possible directly on this device using mplayer. Is
this at all possible with this image sensor, or do I have to use media-ctl /
yavta?
Correct, i've not seen any other way either....
2. The other approach was to use Max Galemin's Buildroot 2012.02. With
"magic commands" (media-ctl / yavta) run as shell scripts I was able to
capture images, but at <7 fps and a color scheme with heavy yellow tint.
(Strangely, changing the number of images to capture also changed the color
/ hue).A couple of extra questions: Has anybody successfully used this imaging
sensor with these kernel versions (3.7.x or 3.2.x), is another kernel
version recommended, or is the problem entirely unrelated to the kernel
version?
Is there some important detail or key information that may have eluded me in
my crusade for amazing image-capturing?
Honestly, beyond getting it to work (take a picture) with v3.2.x,
v3.4.x -> v3.7.x based kernels, i haven't done much with the sensor..
Here's a link to the 2 scripts i use, when testing..
https://github.com/RobertCNelson/tools/blob/master/pkgs/aptina-media-ctl-n-yavta.sh
https://github.com/RobertCNelson/tools/blob/master/pkgs/aptina-test-capture.sh
That's all i got on the subject...
The hardware is the BeagleBoard xM rev C and the Leopard Imaging LI-5M03
with mt9p031 sensor. I feel kind of silly asking about this, because there
is SO much information out there on this already. Somehow, I still can't get
it to work. Need help!If anyone has any ideas or thoughts, they would be greatly appreciated!
Regards,
