The CP2102 I was using to get stuff off the UART is putting 5V on the pins of the prototype, and David says this is a bad thing!  
I am to investigate Serial Wire Debug as an alternative.
I will also try to see if I can get any DW code to run on the eval kit, and see how ahrd to port to the nRF51822.
David is going to build two more protos boards.
