The BeagleBone Black board has been created by Gerald Coley.

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.

UART debug port

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

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).

The BeagleBone Black board has two extension ports using common 2.54mm (0.1inch) pitch:
