Yeah - I got the PCBs for my ARM + FPGA board back from BatchPCB the 
other day. I've been slowly building it up section by section. The ARM 
processor is running & I can talk to it with JTAG. Although I've got 
experience with other varieties of ARM, this is my first time with the 
NXP LPC2100 series and I haven't figured out some of the fundamentals 
yet, so simple GPIO stuff still isn't working. Hopefully I can get over 
this hurdle soon and get the LED blinking and the USB port talking.

A few pictures of the assembly process here:

Once I get the ARM working, I'll add the Spartan-3, SRAM and codec. Then 
it's off to the races!
