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