There's a downloader called ARMLSD (!) here:
I've just tried it, it works fine. Testing the LPC21xx GNU toolchain
on it is next, once I've done that, I won't look back on the IAR and

I can confirm that. Having said that, all I ever look at in an
evaluation kit is the circuit diagram of the board and the data sheets
of the components, and if you do that, it's pretty obvious that the
board isn't powered from the serial cable. The built-in regulator is
great because it's strong enough to power my entire circuit, and you
can just hook 3.3V to VDDIO if you don't want to use it, the regulator
won't matter at all.
The only thing I don't like is the LED hardwired to DAC1, but it's
only a resistor I'll have to remove to get rid of it. And, if I had
designed the board, I would have made footprints for a crystal and two
SMD capacitors to make it easy to add a crystal for timing accuracy
(which I need).
I think the ADuC7020MK is the best (only?) way of building a circuit
with 4 DACs without making a PCB or having to deal with the
non-standard dimensions, unwanted connectors, etc. on the full QS
version. In other places, you pay $30 for a cable alone, so I think
this is a great offer.
Oh, and I don't use the 9V battery clip either, it goes straight to a
2.1mm power supply plug (via a Schottky for protection) to get the 6V
from a wall brick down to 3.3V (there are not many wall bricks with
3.3V, so the build-in regulator is great!).
