ESP32 WROOM GPIO during boot

[davefes]

I am aware that some GPIO should not be used as their state can be undefined during boot. I have several lists of "acceptable GPIO" and on that list is pin33.

On a dev board pin33 stays low during boot. On a bare module board that has lots of other stuff (LoRa transceiver and an ADC) connected to various GPIO, pin 33 goes high ... briefly during boot.

Before I go ripping-off all the connections to see if another port is having an effect on pin33, are GPIO states during boot consistent across all production chips or are their behaviour non-deterministic?
