esp32.wake_on_ext0 not workingon esp32s2

[kjm1102]

Port, board and/or hardware

esp32 port, waveshare ESP32-S2-Pico

MicroPython version

MicroPython v1.23.0 on 2024-06-02; Generic ESP32S2 module with ESP32S2

Reproduction

import os,time,esp32 from machine import Pin,deepsleep

time.sleep(5) pb=Pin(0, Pin.IN); esp32.wake_on_ext0(pb,0) deepsleep(10*1000)

Expected behaviour

Loaded the file as main.py then reset the board. Expected s2 to either deepsleep for 10s or exit deepsleep when I press the button connected to gpio0.

Observed behaviour

The s2 exits deepsleep immediately after entering it. This can be verified with a usb ammeter in series with the usb powering the board. I did not include print commands because having a usb repl active often plays badly with deepsleep.

Additional Information

esp32.wake_on_ext0 works OK with deepsleep on an esp32 v1.23.0 so I figure the instant wakeup on the s2 is down to it being an s2.
