First of all you will need to have USB to TTL UART module for example:
Also you can use Arduino by using it in DFU mode (connecting reset and ground).
The UART connector on X1 has 3 pins - TX, RX and GND.
*Note that TX has to be connected to RX and RX to TX
After you attach the UART port to the TTL to USB adapter you can connect to it using any terminal program pointiong to the appropriate com port, in my case it is COM3. I would recomend using Putty or Kitty as the terminal.
In Putty's window select connection type as Serial, in Serial line enter COM port where your TTL adapter is.(For me it was COM3) and in Speed edit box enter 115200 and click OPEN button.
Now after you power up your X1 you will start to receive the clear console text in to the terminal.
