PPS-GPIO on Rock64 with Armbian legacy (4.4.X) kernel

About

This gist covers how to enable PPS input via GPIO for Rock64 SBCs running Armbian legacy (4.4.X) kernels. It may also be applicable to Pine64 SBCs and other kernel versions but I have not personally tested them.

This gist will not cover configuring ntpd or gpsd to utilize the PPS signal, only enabling pps-gpio via modifying the device tree. For help configuring ntpd or gpsd I recommend the links under Motivation

Motivation

A PPS (Pulse Per Second) signal allows a time server to improve its clock accuracy and therefore achieve Stratum 1 status. Typically a PPS signal is provided via a GPS receiver attached to the server. The GPS receiver also provides a coarse time via USB or serial connection.

About

This gist will show how to setup Raspbian Stretch as a headless Bluetooth A2DP audio sink. This will allow your phone, laptop or other Bluetooth device to play audio wirelessly through a Rasperry Pi.

Motivation

A quick search will turn up a plethora of tutorials on setting up A2DP on the Raspberry Pi. However, I felt this gist was necessary because this solution is:

• Automatic & Headless - Once setup, the system is entirely automatic. No user iteration is required to pair, connect or start playback. Therefore the Raspberry Pi can be run headless.
• Simple - This solution has few dependencies, readily available packages and minimal configuration.
• Up to date - As of December 2017. Written for Raspbian Stretch & Bluez 5.43
