How to use already allocated GPIO pins


I want to use the uart of beagleboneblack. I want to use the RTS and CTS pins for that, but the those to pins already allocated to i2c2.

How can i disable them for i2c2 and How can i use it?

Thanks in advance.

You can use libpruio to re-configure the pins. Are you really sure that you want that? AFAIR i2c2 is used for the communication between the CPU and the power control device.

The CPU has six UART devices. You can use ie. UART2 on P9, pin 21 and 22 (in mode 1) without disabling i2c2.
