PyPortal stopped reloading on code.py change Moderators: adafruit_support_bill, adafruit

Howdy,

I've been having a lot of fun with my new PyPortal the last few days. Last night it suddenly disconnected from PuTTY and now will no longer reload when code.py is changed (or frankly any file). It also doesn't respond to Ctrl+C or Ctrl+D, though it does show print output. It's worth noting that previously it would show up as COM3 and now it's COM5 in Device Manager.

It does pick up the new code when the reset button is pressed or USB power is applied. I know the USB cable is good as it's from a USB 2.5" HDD; plus the PyPortal does see the new code on hard reset.

The bootloader is flashed with update-bootloader-pyportal_m4-v3.14.0.uf2 and I'm running circuitpython adafruit-circuitpython-pyportal-en_US-7.1.1.uf2.

I've attempted re-flashing the bootloader and circuit python, but neither seemed to help.

The contents of boot_out.txt are as follows:

Code: Select all | TOGGLE FULL SIZE

Adafruit CircuitPython 7.1.1 on 2022-01-14;

can you re-activate it with

Code: Select all | TOGGLE FULL SIZE

import supervisor
supervisor.enable_autoreload()

?
Or maybe

Code: Select all | TOGGLE FULL SIZE

supervisor.set_next_code_file(...)

will fix it temporarily at least. See https://circuitpython.readthedocs.io/en/latest/shared-bindings/supervisor/index.html

Try erasing and reformatting CIRCUITPY from the REPL:

Code: Select all | TOGGLE FULL SIZE

import storage
storage.erase_filesystem()

Save any files you don't have copies of of, if you can.

Got it working, thanks!

I reset the file system, then uploaded my code.py file and auto-reload still wasn't working. So I reset it again and tried modifying the Hello World file and it worked.

I eventually realized that the try...catch I had inside my while True loop was interfering with the reload mechanism.

Ah yes. CTRL-C and auto-reload both use exceptions to exit the running program. You can catch them with a blanket try/except. Thanks for letting us know that was the issue.
