I am trying to scan the JTAG chain and verify that this device shows up correctly in the chain. It looks like the TDO signal is never toggling.
I have verified CLK/TMS/TDI and they look good.
The datasheet indicates that to reset the JTAG it needs 3 clock cycles with TMS high. I see about 6 clock cycles with TMS high.
I have tried with the strapping bits set for: JTAG Boundary scan and RGMII to 1000Base-X, with no difference.
Is there something else that needs to be done to make this work?
