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.
You can get the images here: Images for Orange Pi 3 board (Not yet available as my ADSL upload would not support it :( ).
Connection and startup
USB-UART serial console connection
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
