Hi,
Could you not have searched for them rather than giving up as soon
as they were not where you thought they should be. It took seconds
to find them.....
cd linux-2.6.10_mvl401
find . -name mt9t001.[ch]
./drivers/media/video/davinci/mt9t001.c
./include/media/davinci/mt9t001.h
./include/config/video/mt9t001.h

Subject: Where can I find mt9t001.c
Hi,
I have checked the following folder:
\home\icer\workdir\lsp\ti-davinci\drivers\media\video\
\home\icer\workdir\lsp\ti-davinci\include\media\
and I can not find either mt9t001.c nor mt9t001.h file.
I did all of the setting as this literature:
LSP 1.20 DaVinci Linux CCDC Driver
User's Guide
Literature Number: SPRUEP7
<*> Video for Linux option
--> <M> Davinci Video Capture
Could anybody tell me how to find those files or mail me a copy as
attachment? Thank you !

Vim,
I've checked yet those folders. The I2C address of my physical
device should be 0x21 (videocam OV7670), so I would expect to find a
device file
/sys/bus/i2c/devices/1-0021
But I don't see it.
Instead I see the installed driver
/sys/bus/i2c/drivers/ov7670
I'm wandering if anybody knows how to speed down the I2C bus.

Oggetto: Re: I2C bus probe utility
Hi Gabriele,
I used the device and driver files in /sys/bus/i2c/devices and
/sys/bus/i2c/drivers to help debug my i2c problems. You can see
which devices are registered and what drivers are available.
I did not have to change the bus speed, so I haven't looked into that.
Hope that helps,
-Vim

Hi,
I'm facing with some problems on the I2C bus.
In the u-boot command list there is a specific command to probe all
valid addresses on the I2C bus (iprobe), but I'm not sure it is
working good.
1. Is there any similar utility within the kernel?
2. How can I reduce the bus speed?
Regards,
Gabriele

Vim,
I've solved eliminating a couple of 22 ohm resistors I placed in
series on the bus lines.
Thanks
