Getting started with BeagleBoard-xM

1. Use a 5V external power supply

Powering your BeagleBoard using USB OTG often causes booting fatal problem.

2. Prepare a serial cable

The BeagleBoard-xM provides a female DB9 port and requires a serial cable to connect the console to your host system. A DB9-to-USB cable does not work to me since I saw lots of junk data in the Hyper Terminal window or Tetra Term window in my Windows XP. The UART setting is:

Baud rate: 115200
Data: 8 bit
Parity: None
Stop: 1 bit
Flow control: None

3. Booting Angstrom Linux.

Boot Angstrom on the BeagleBoard-xM is with the microSD card that comes with the board, which contains an Angstrom image. Then you will see the Angstrom login console, then log in as root, no password. Then you are in root directory.

Some USB/serial adapters work just fine, others are junk. Don't totally dismiss the use of a USB/serial cable, it works just fine for me.
