Kinetis FRDM-KL25Z with external debugger

Here is how to attach external debugger to Kinetis CPU on FRDM-KL25Z board. Like we are used to by now the debug connector on the boards with an on-board debugger is used to connect the on-board debugger to board without it. Anyway the debug connector can be used as input when on-board debugger is put in reset. This is done with jumper on the other debug connector. I.e. on the debug connector for the on-board debugger (debugging a debugger - there's a thought for you :) ).

You might need to chip away a bit of debug connector housing due to C7.
Probably not if you are just using pinheader.
