I bought a BeagleBone Black in order to create easy network services. First of all a DNS

First steps

Get the miniroot iso

Copy to external SD card

First step: erase the entire SD and put the iso :!: Goodbye data :!:

dd if=miniroot-am335x-57.fs of=/dev/mmcblk0

:!: Example taken from linux :!:

Connect the board

Insert the SD, connect the board with a special USB cable ( like this one)
With this cable you MUST NOT connect the red cable (+5V will grill your nice tool!)
Connectors are in this order:
Power up the board holding down the boot button.
Connect to /dev/ttyUSB0

 sudo screen /dev/ttyUSB0 115200

When you boot you arrive on:

cpsw0 at omap0: version 1.12 (0), address 1c:ba:8c:a2:4f:0d
ukphy0 at cpsw0 phy 0: Generic IEEE 802.3u media interface, rev. 1: OUI 0x0001f0, model 0x000f
scsibus0 at sdmmc0: 2 targets, initiator 0
