storage.remount disable_concurrent_write_protection

[mikeysklar]

CircuitPython version

CircuitPython 9.0.5
Feather RP2040

Code/REPL

import storage

# Remount the filesystem as writable with concurrent write protection disabled
storage.remount("/", readonly=False, disable_concurrent_write_protection=True)

Behavior

Still seeing drive mounted as read-only when laptop is rebooted, but Feather is powered from USB hub.

Description

In this case the desired behavior is to override the write_protection so development work can be resumed when the computer USB connection comes back.

MacOS Ventura (13.6.3)
MacBook Air M2

Additional information

Based on Forum Thread from @blakeBR who shutdown his Windows desktop each night and would like to resume work on his USB hub powered controllers in the AM. His testing was on Windows and mine was on MacOS.

simple cpu temp code running as code.py

while True:
    print(microcontroller.cpu.temperature)
    time.sleep(5)

Is the remount in boot.py? Could you check boot_out.txt and see that no errors were written there?

Also please try 9.1.0-beta.3.

[RetiredWizard]

Can you post boot_out.txt, code.py and boot.py contents from the device?

[RetiredWizard]

I just looked at your linked forum post and it looks like you're using a powered USB hub? If that's the case, I'm wondering if the CircuitPython device is simply not restarting when you're rebooting the laptop. The boot.py wouldn't re-run in that case and perhaps the storage.remount command needs to run after the OS initially mounts the drive.

Yes, both @b-blake and I are using powered USB hubs so the controller continues to run when the attached PC goes away.

Everything works as expected when the Feather RP2040 is reset. Things don't go well when the PC goes away and comes back. It is either read-only mount or no mount of the CIRCUITPY drive.

@dhalbert;

Is the remount in boot.py?
Could you check boot_out.txt and see that no errors were written there?
There is no remount in boot.py
There are no errors in boot_out.txt

This is the output of CircUp.exe this morning from my Windows 10 PC after having it off all night. It was the first thing run at boot-up. If you want specifics about any device. please ask.
