UART is a little tricky. You can use the serial console (ttySAC2),
but then you have to make sure that the kernel doesn't print anything
and that nothing else tries to read the console (stealing the data
the board sends to your application.)
I see that the Phoenix board can also use USB. So that may be an
option as well.

Hmm, does it ? As far as I know, it should work fine from battery.
Of course, then you either need to worry about battery life or
connect some other supply to the battery terminals, which may or
may not be suitable for your setup.

Yes, GTA01 has these GPIOs too. The registers that control them are
even at the same address in the 2410 and the 2442, so the "gpio"
program works on both.
