"PP3V3_AWAKE = 0 volts"
Diode mode to ground?

All AWAKE and SLPS2R voltages must be present at the beginning.

Ohh, I see.

Diode mode for PP3V3_AWAKE = 0.579

PP3V3_AWAKE is actually 3 volts sorry about that.

PP3V3_S5 = 0.40 volts and diode mode is 0.290

If ALL SLPS2R and AWAKE voltages are present, DFU mode is the next step...
