UART Notes~

This document provides specific installation procedures for configuring the UART on a Raspberry Pi version 1 or 2.

On the Raspberry Pi 2 and later, the UART is handled differently due to the addition of Bluetooth, so different setup instructions are required. If you are installing AoT on a Raspberry Pi 3 or later, perform the following steps to configure the UART:

Run raspi-config

sudo raspi-config

Go to Advanced Options -> Serial and disable it. Then edit /boot/config.txt.

sudo nano /boot/config.txt

Find the line "enable_uart=0" and change it to "enable_uart=1", then reboot.
