Hi,

I am usinh lm-suit with the zipper board with LMS6002D. I am trying to run the register test, but the last part is failing. Another post suggested to swap r63, with and 100 ohms resistor, which I have done.  
So far I have done the following:

1. Plugged in myriad rf board to the zipper board.
2. connected usb cable to laptop
3. connected external 5volt supply
4. run register test with following output: (always the vtune that is failing)
