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.

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 On Sep 17, 2008, at 5:56 AM, Gabriele Filosofi wrote: 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?
