Behavior

When using CircuitPython >= v9 on Raspberry Pi Pico, the file system (CIRCUITPY) is mounted Read-Only when the Pico is connected to a Raspberry Pi Desktop Debian 11.10 virtual machine.

Versions 8.x of CircuitPython seem to mount the file system (CIRCUITPY) as read-write.

(This is is possibly due to the age of my system or my inexperiance with CircuitPython/Pico.)

I did notice the one of the versions that loaded RO had the following in journalctl, which did not appear in the RW mounted version.

What happens if you try the board directly on the RPi without using a VM?

Also try erasing and reformatting CIRCUITPY. 

import storage 
storage.erase_filesystem()
BusterRaid commented 4 days ago

Hi.

Thank you for the reply.

On the "original" set up (Dell 490-Win 10 VM host running "Raspberry Pi Desktop - Bullseye, 11.x" as a VM and the Pico connected to the VM):

import storage 
storage.erase_filesystem()

.. did not resolve the issue.

After running the command the Pico seems to be "ejected" from the VM and then reconnected. However the Pico is (re)mounted as ReadOnly.

When directly connecting the Pico to a Raspberry Pi 3 Model B Plus Rev 1.3 running Raspberry Pi OS Bookworm 12.x, the Pico seems to be OK-it is mounted as ReadWrite.

At the moment I dont have access to a physical Pi which is running "Raspberry Pi OS - Bullseye, 11.x". I'll see if I can spin one up tomorrow.

The current version of the x86 desktop (which I use for the VM) is "stuck" on Bullseye - there is no Bookworm version.

As I do most of my tinkering on a VM, I'd like to get the Pico/CircuitPython combo working when connected to this Raspberry Pi Desktop - Bullseye VM.

dhalbert commented 4 days ago

We have not seen problems like this with Bullseye on a physical RPi, so I suspect it is something about using the VM, perhaps something about the VM settings.

Can you see the serial connection from the VM to the board, and connect to the REPL? If not, that may be confusing the issue.

Can you see the serial connection from the VM to the board, and connect to the REPL? If not, that may be confusing the issue.

I think I can (it's all a bit new to me) - I'm using Mu on the Pi VM and the option "serial" is available and seems to work - it seems to connect and I can run stuff on the Pico (e.g.: turning the onboard LED on/off). This is the case for both Circuit Python v8.x and v9.x versions that i have tried.

Some other tests I carried out:

- For Raspberry Pi Desktop, Bullseye (VM), CircuitPython en_GB-9.0.5:

The Pico is mounted ReadOnly. There is no change to this behaviour if, within the hypervisor, I set "USB compatibility" as 1.1, 2 or 3 between reboots of the VM.

- For Raspberry Pi Desktop, Buster(10.13) (VM), CircuitPython en_GB-9.0.5:

Mostly a vanilla install, with updates. The Pico is mounted ReadOnly.

- For Debian Bullseye(11.10) i386 (VM), CircuitPython en_GB-9.0.5:

Mostly a vanilla install, with updates. When using the hypervisor option "Connect (Disconnect from host)", the Pico is connected to the VM but not automagically mounted. Mounting via the "CIRCUITPY" icon on the desktop causes the Pico to be mounted ReadOnly.

Issuing the mount command:

`mount -t vfat /dev/sdb1 /media/user1/CIRCUITPY -o rw`

... elicits the response:

`mount: /media/user1/CIRCUITPY: WARNING: source write-protected, mounted read-only.`

... suggesting the device is being considered as a ReadOnly USB device.

In summary: CircuitPython en_GB-8.2.10 - OK on every VM I tried. - Mounted as ReadWrite. CircuitPython en_GB-9.0.5 - Not OK on every VM I tried. - Mounted as ReadOnly.

If using "CircuitPython en_GB-9.0.5", the Pico is mounted on the HOST machine (the Dell Windows 10 physical) as ReadWrite. Once the Pico is connected/mounted to a VM its file system is "set" to ReadOnly. Shutting down the VM (returning the Pico to the host), the Pico file system is remains ReadOnly. Removing the Pico from the host and reinserting it restores the filesystem to ReadWrite.

I agree the issue is almost certainly in the hypervisor handling of the USB device but the behaviour seems different between CircuitPython versions v8.x and v9.x (Caveat: I have tested a few of the available v8.x and v9.x versions).

Thanks.
