What switch? Is it on a card or directly on the board? > Can you probe reset, power, and clocks? A broadcom switch. It is directly on the board. I tried to probe SD1_PLL_TPD (PLL test point Digital, pin V28 on MPC8536 E), there is no signal there. What Should I observe in this pin? I was expecting to observe the internal serdes clock signal.
