Well, according the PDF in the zip file refers to 9835 and 9735,
and the data sheet link says that a 9835 is a PCI UART + parallel
port, i.e., seems like the chip is destined for use in boards
that add a parallel and serial port to your PC. In this case,
the serial port has been attached to the LPC.

Well, if you can load programs to the LPC2114, you clearly have
flash downloading etc working. You can get by without a debugger
pretty easily. I've never used one with the LPC parts.

Start out with a startup file that sets up the vectors correctly
and turn on an LED. Then work on a startup file that sets up the
C environment and write a main.c that turns on an LED, ... small
steps, make sure you understand each step. Then you'll understand
how things work.

Don't blindly assume that you can just take GNUARM tools and
get things to work on your processor.

If you don't understand the above comments - ask more!
