Test NameStatusNotesModified
Board Status 1 Unable to load connectivity firmware, set aside for further investigation. (AM) Preliminary diagnosis misc chip failure, the chip fails the readback verify test in impact. The misc chip is holding the reset/autorestart pins (6,5) on the qpll chip low, therefore suspect no clock (7/11/07). QPLL chip pins 6 and 7 shorted together. The soldering on this side of the chip is of poor quaility. This was fixed and the board starting to function, see Richards message below. I had to reflow each pin with a solder iron tip. I attempted to reflow with air/heat only, however, the solder would not flow. I was concerned about excessive heat damaging the board (Richard 7/11/07). 19-07-2008
