WR2RF board valididation
Introduction
This page provides a list of checks that have been performed on the WR2RF platform. We have utilised these checks to validate the basic functionality of the WR2RF board. There could still be issues with the implementation of the FPGA but these can be addressed later. The aim here is to catch errors in the PCB and components.

Checklist
Here we provide the complete checklist and the status for each of the four prototype boards received in December. Board 0001 has proved problematic so far, and is likely to undergo some rework with DEM. Y - indicates a successful observation, N - indicates the board didn't respond as expected and finally U - indicates unknown. Unknown status can occur because earlier failures in the validatation procedure prevent further checking (e.g. board 0001) or the board hasn't been fully validated (e.g. board 0004 as it is currently with RF).
In many situations, we are inferring the correct operation of components and PCB by observing, higher level functionality. This could be a mistake...
