How can we set pl011 uart with transmit fifo and receive fifo enable in raspberry pi?

You don't have to do anything.

The PL011 UART is enabled by default as device /dev/ttyAMA0. The Linux driver handles the FIFOs and has additional buffering.

  • Also...I believe if you disabled it at some point and want to re-enable it you can do so via sudo raspi-config under advanced options in the newest version of Raspbian?. – NULL Jun 8 '15 at 13:33
