strange output with os.listdir()

[cyrano1960]

Hi there, I am working with an Heltec ESP32 board and I have installed MicroPython v.1-10 for a while and it works. But now I have started it up again and I got the REPL and I can enter commands such as

Code: Select all

print('hello')

without problems. If I check my directory on the ESP32 using rshell I will get the correct output, but if I use

Code: Select all

import os
os.listdir()

in the REPL console, I will get the following result:

os-listdir.JPG (20.25 KiB) Viewed 1566 times

It seems to be an address but what went wrong? Could somebody help me? Thanks a lot in advance!

Update:
A very very stupid mistake. I have turned on the "heap mode" in Thonny, so it will output the addresses.
