Hi nvidia,
I have two questions about ball B37 (USB0_VBUS_DET) on the TX2.
- Is the pin 3.3V tolerable?
- Can this pin be left floating and still allow RECOVERY mode flashing?
I have found these two related topics:

@Trumany states that the pin Voltage Input High threshold is typically 1.1V to 2.1V which is clearly above 1.8V logic level hence I’m hoping that the pin is indeed 3.3V tolerable:

@Trumany states that the USB0_VBUS_DET signal is not required for FORCE_RECOVERY to work - is this 100% certain? → The reason I ask is that if the pin is not 3.3V capable then I will have to cut the trace to it and leave it floating.
Yours truly
