A problem occurred in EVM6472

I am using EVM6472 and have a problem.

This problem is that POST LEDs does not turn on,
and it resembles item 2 of document "EVMC6472 Known Issues",
but I am using EVM PCB version 17-00065-06.

In addition, this problem prevents connection of an emulator,
and it can be removed after having been in the state that turned off a power supply for a long time.

Is this problem known?

Best regards,

Daisuke

    Hello, everyone.

    About this problem, the root cause is unknown, but only the obstacle for me was removed.

    The means is that the immediate boot is chosen as for the boot mode selection and the pin for the RS232 cable is chosen as for the com port selection.
    In other words all SW2[4:1] is off, and Shunt installed over J10.3-J10.5 and J10.4 -J10.6.

    Best regards,

    Daisuke
