Hi Emanuele,
Thanks for your input. Pls let us know how to go about with Kernel
media/video drivers? If you have any suggestion pls let us know.

Hi,
I think that if you want acquire from a ccd (more correctly CMOS) you
must modify media/video kernel drivers. Now, I think, are to much vertical
versus TVP5146 in the DVEVM. I have created a driver for MT9M001C12STM but I
can't test it because the hardware should arrive. In every case it is
difficult to remain completely inside the v4l2 spec. For example my sensor
is 1280 x 1024 x 10 bits... and this format it is out of v4l standard.
If someone is interested to this, just ask.
Emanuele

Hi Yogesh,
Thanks for your interest. I am herewith attaching the V4L2 code
which we have modified to acquire CCD data. We are getting some garbage
data..
Pls let us know where the problem is??

Hi,
I've been skimming through all the posts that talked about
Interfacing CCD sensor (MT9T001P12) to DaVinci
I got bits here and there from all you posts but I'm still confused
and unclear as how to do it.
if anybody has completed please helpme out,or if sombody is
developing i would like to join hands for the development.
thanks

Hi,
Yes, you are right about that "SPRAA52".
By following all the information as mentioned in "SPRAA52", I
suppose you can connect this DaVinci DVEVM with Mt9t001 CIS. And I already
did it successfully!
And regarding those Linux drivers (I2C, CCDC...), I have contacted
technical service guys in ti and they replied that, "they are working for a
demo device driver and will release it 1Q07. They remove a lot information
in the VPSS data sheet if you have old version and compared it with current
version.
I also have a prototype drivers for my project so far but the
performance still need improvement. And I am working on this ?
2007/2/16, Chezhya\ P <[EMAIL PROTECTED]>:
Thanks for yor feedback. I would like to know the following
Have you interfaced this CCD sensor to DM642 or DaVinci because
the application note "SPRAA52" is for interfacing with DM642.
Do we have the patch for MT9T001P12 with respect to
1. I2C driver
2. Video capture driver

P.Chezhyan

Hello,
I use the same CIS chip as you described.
You can check ti's document:
"SPRAA52 "
for more detailed information include schematic.
If you have more questions, please let me know.
Also you have to pay attention to DC4 pin 2.
That's all.
