Thank you for your response.
We do not have a pull down resistor on pin 38. Pin 38 is tied to a level shifting isolator IC and then to a relay. The relay is closing on startup due to the GPIO pin going high on power up before the UserMain()
starts.

Nano GPIO pin 38 pre UserMain()
After power is applied and
Before UserMain() runs and inits GPIO pin 38 to 0,
we are seeing pin 38 go high. Is there a way to control the reset value
pin 38 defaults to pre user program execution?
Using Pin 38 as GPIO output.
