So, no init system or anything? Your terminal probably hasn't been set up. This is a surprisingly tricky bit of "magic" done with a special syscall which we're for the most part happy to let some linux distribution do for us.
One workaround for it, funny enough, could be ssh-ing into your device. A virtual terminal should be close enough.
I was sure that busybox had a utility for it, and their faq turns out to have that and a better explanation what it does:
Quote:
"Why do I keep getting "sh: can't access tty; job control turned off" errors? Why doesn't Control-C work within my shell?"
Job control will be turned off since your shell can not obtain a controlling terminal. This typically happens when you run your shell on /dev/console. The kernel will not provide a controlling terminal on the /dev/console device. You should run your shell on a normal tty such as tty1 or ttyS0 and everything will work.
Example: you booted into your machine with init=/bin/sh and got "sh: can't access tty" error because sh has its stdio opened to /dev/console. You want to reopen stdio to, say, /dev/tty1 and thus acquire a controlling tty.

ttytype
TTYTYPE(5) Linux Programmer's Manual TTYTYPE(5)NAME
ttytype - terminal device to default terminal type mapping
DESCRIPTION
The /etc/ttytype file associates termcap(5)/terminfo(5) terminal type names with tty lines. Each line consists of a terminal type, fol-
lowed by whitespace, followed by a tty name (a device name without the /dev/) prefix.
This association is used by the program tset(1) to set the environment variable TERM to the default terminal name for the user's current
tty.
This facility was designed for a traditional time-sharing environment featuring character-cell terminals hardwired to a UNIX minicomputer.
It is little used on modern workstation and personal UNIX systems.
FILES
/etc/ttytype
the tty definitions file.
EXAMPLE
A typical /etc/ttytype is:
con80x25 tty1
vt320 ttys0
