testing machine deepsleep

[serafimsaudade]

import machine
import pycom
import os
import time

i=True
while i==True:
    print('normal mode 5sec')
    time.sleep(5)
    i = False

print('deepsleep mode 5sec')
machine.deepsleep(5000)
print('deepsleep done')

Hi,
I'm trying to run this code. But the last print never appear.
I'm running the latest fw.

Cumps,

Hi guys,
After done some test I realize that the GPY only exist from deepsleep if is power with 5V.

If I power the GYP with 3.5V it hangs forever in deepsleep.

This is normal?

Cumps,

I'm connected to the gpy over uart, and the reset never occur.
:(

update: today I will update the firmware, and give another try.

@serafimsaudade That would be the expected result, as when the board wakes up after deep sleep, it acts as a reset and it restarts from the top of boot.py + main.py. During deep sleep RAM etc. are not powered, so the board can't just resume execution at the next instruction.
