I don't understand. You *are* doing that write to FSD? That is causing
your problem. The 0x40020000 enables the power button fail-safe for
exactly 4 seconds. I would think it should be 0x80000000 for a system
with no power button. (lock the power button disabled)
In another mail, you mentioned the the power button is unconnected. That
isn't valid, the input needs a button and pullup, or it needs to be
grounded (see the "skip" feature in the datasheet)
