I don't know what the U-Boot setup in the Freedombox images looks
like, but if you see U-Boot starting on the HDMI screen, you
could try to interrupt U-Boot's boot process by pressing any key
on the keyboard, so that you get a U-Boot commandline prompt, and
enter the the following two commands:

setenv console "tty0"
run bootcmd

Many U-Boot bootscripts (including the one installed by the
Debian flash-kernel package for the LIME2) pass the U-Boot
"console" variable to the kernel.  If that is the case for the
Freedombox images, the aforementioned commands should make the
console on the HDMI port the primary console for the current
session.  If that works for you and you want to make it a
permanent default, you can run the following commands at the
U-Boot prompt:

setenv console "tty0"
