I am having the same issue with my BBB. Modifying the device tree with values that should run the I2C clock to 400 kHz does not seem to change the speed upon rebooting. I validated that the .dtb was modified by unpacking it into a .dts again to check if the value was 400 kHz.
Is this method of modifying the device tree not effective anymore in the latest images of Debian? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
