Hey all, I am trying to connect to the parrallela board via the serial pins so that I don't have to use an HDMI monitor and USB hub for keyboard/mouse. I bought the RPi Serial Connection wires to connect to the parrallela pins, and downloaded putty to connect to the parallela board as detailed here: http://www.elinux.org/RPi_Serial_Connection

The connection seems to work fine and data is being passed, but whenever the script gets to:
"Starting kernel ...

Uncompressing Linux... done, booting the kernel"
It simply hangs here indefinitely. What I think SHOULD happen is i should be given a login prompt. Any thoughts on how to fix this?

The following is my putty serial port settings:
Serial line to connect to: COM4
Speed (baud): 115200
Data bits: 8
Stop bits: 1
Parity: None
Flow control: None

I have also tried to connect my hdmi monitor while I am trying to use putty to login thinking that maybe the OS wasn't starting the login script since there wasn't a console plugged into its mini-hdmi port, but this was to no avail.

I would greatly appreciate any insight into this you good people could offer.

The serial output is disabled in the kernel, if you want to enable it you need to edit the device tree and and compile it. (using "dtc").
