Success!!!!!

I swapped the green and white cables and ran:-
cu -l /dev/cuaU0 -s 115200
... and got:-
Code:
U-Boot 2014.04.R2-1 (May 15 2014 - 14:36:05) Arch Linux ARM
Seagate GoFlex Home
If I want to do something similar with a Raspberry Pi which pins should I use?

I'm guessing:

Pin6 black
Pin8 white
Pin10 green

The syntax for logging:

cu -l /dev/cuaU0 -s 115200 | tee /var/log/cu.log

The other way to do logging: Install minicom, and use it instead of cu. It has logging built in (calls it "capture"). And another zillion functions. So many that one actually has to read the documentation to use it. Some of the other functions might actually come in handy though.

Then run the terminal program cu to view text onscreen while the GoFlex boots up.

My Prolific UART adapter shows up as port cuaU1. So I use this:
Code:
[CMD]cu -l /dev/cuaU1[/CMD]
Connected
Is there any way to interrupt the boot process without dropping the connection?

I want to enter commands to u-boot before the boot process finishes.

Just press the key you want to send. Or is that not working for you?

The keyboard became inactive for some reason.. a reboot sorted things out.
