As another means of checking that the Device Tree Overlay from this example is working, I changed the clock-frequency to 200kHz to ensure the same output can be seen on the oscilloscope.
After loading the device tree overlay and running i2cdetect, I had the following output on my scope. <https://lh5.googleusercontent.com/-OExs5be9KhI/VDrddvgAokI/AAAAAAAABv4/SovY_CPaGm8/s1600/F0004TEK.JPG> Notice in the image above that my scope is now reading 147.2kHz on the clock line as opposed to the previous measurement of 86.35kHz when the clock-frequency was set to 100kHz. Why it's reading 147kHz rather than 200kHz is a mystery to me. But at least it proves it's changing as I alter & reload the device tree overlay. As always, any input to this is much welcome. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
