The BeagleBone Black board has been created by Gerald Coley.
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 the u-boot, kernel image, and Devuan root filesystem I built.

Connection and startup
USB-UART serial console connection
On the J1 connector (6 pins male 2.54mm, next to P9 connector, pin 1 on the Ethernet side) :
- pin 1 - GND : Black
- pin 4 - UART RX : Orange
- pin 5 : UART TX : Yellow
= SD card boot
- If the internal Flash (emmc) is empty the board automatically boots on the µSD card.
- Otherwise, you must hold the S2 push button (above µSD card) when powering up the board.
- You can also solder two of the S2 push button pins on one side (no need to do it on both sides of the push button).
