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 the u-boot, kernel image, and Devuan root filesystem I built.
On the J3 connector (3 pins male 2.54mm, next to the Ethernet connector, pin 1 on the board edge) :
pin 1 - GND : Black
pin 2 - UART RX : Orange
pin 3 : UART TX : Yellow
SD card boot
The OrangePi Zero 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
Extension ports
The OrangePi Zero board has two extension ports using common 2.54mm (0.1inch) pitch:
con4 : 2x13
con5 : 1x13
