I have just managed to get the first program into my lpc2104, so I hope
I can help you a bit.

Talk to the bootloader: connect the LPC UART with a level shifter like
the MAX3232, pull down pin 44, Reset the chip and start a terminal
program with 9600,N,8,1 and type ?. You should get the answer
"Synchronized", otherwise something is wrong. You can play with the
bootloader a bit if you like, the protocol is all ASCII, just look into
the Datasheet and User Manual for details.

Connect some LEDs to P0.8-P0.15. Then get the led.hex file from the file
section of this group and upload it via one of the ISP Tools. I used the
one from <http://www.clibb.de/> running under Linux, there is also a
Windows version on the page and you can get one from Philips. After a
reset with pin 44 open the LEDs should blink.

Build or get the gcc toolchain. Get the lpc2106_gcc archive from the
files section. Adapt the RAM size in the .ld file at 2 locations if you
have a 2104 or 2105. Compile the program and upload it. Again the LEDs
should blink.

Then you can try some modifications to the LED program or start with
whatever you want.
