On the BeagleBone Black, it's not all of the /dev/i2c-* devices that are enabled by default. Then, connect the BeagleBone Black hardware to the I2C device. Physical address of the hardware blocks, for example, the I2C block on the BeagleBone is supported by the same driver as the one on the original Beagle boards. But while inserting the driver into the kernel, I see the probe function being called. Also check that on the Beaglebone side the you don’t have any cape connected to I2C and that the I2C drivers are correctly installed and configured.

However, for some. linux gpio driver for beagle bone. org GSoC 2013 : Minix I2C Drivers for the BeagleBone Black BeagleBone debugging with OpenOCD The original BeagleBone (White) comes with a built-in JTAG emulator which allows you to debug your code without needing to go out and buy an expensive JTAG debugger.
