What is the reason?

ESP32 WROOM

Version: v1.18.0
SDK version: v2.0.0-alpha.118
Build date: 2023-11-03T09:18:28Z


import esp32
import gpio as GPIO

GPIO_LED_RED ::= 2

main:
restartReason := esp32.resetreason
led := GPIO.Pin GPIO_LEDRED --output
led.set 1
sleep --ms=1000
led.set 0

if restartReason == 1:
led.set 1

while true:
sleep --ms=1000

What is the value you get?

7 or 8

8 is deep sleep. That would sound reasonable in many cases

I agree that's strange.

:🎯: it works (reset_reason == 1) properly, if powered via Vin (5V or 3.3V, but not USB)(edited)

USB should just be 5V.
Which board do you use?
