Orange Pi 3

Description

Official website : orangepi.org/Orange Pi 3/ (Backup)

The OrangePi 3 board is an Open-source Single Board Computer (SBC) of 93x60mm created and sold by Xunlong.

Base system

• Create initial system from scratch (sources): all the steps, using u-boot and Linux kernel sources.
• Rootfs guide to create either a minimal system using Busybox or a full Devuan GNU/Linux system.
• The "SD card creation" section from the "from scratch" page : also provides information to use u-boot, kernel, and Devuan root filesystem I built.

UART debug port

On the J3 connector (3 pins male 2.54mm, next to the power button and micro USB port, pin 1 on the power button side) :

pin 1 - GND : Black

pin 2 - UART RX : Orange

pin 3 : UART TX : Yellow

SD card boot

The OrangePi 3 board boots from the SD card which has to be prepared following specific steps. Follow the "SD card creation" section from the "from scratch" page
