Description
I have been running the slideshowsd.py example bleow as code.py on a PyPortal with current master with no data connection, just a wall supply. After a few hours, the slideshow stops and I see on the screen that it has entered safe mode. The reason is not displayed. If I then do a hard reset, it restarts the code.py slideshow normally.
May be related to #1681 but no USB connection is necessary and once started, this code does not write to the REPL.
