CircuitPython version

Version en-GB-8.1.0 is mounted read-write.
Version en-GB-8.2.10 is mounted read-write.
Version en_GB-9.0.0-beta is mounted read-only.
Version en_GB-9.0.5 is mounted read-only.
Version en_GB-20240626-main-PR9375-396aaef (latest at test) is mounted read-only.

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.

Additional information

Environment:

  • Raspberry Pi Pico (not W):

No modifications.

  • VM hypervisor/host:

Dell 490 Precision.
Intel 5000X (Greencreek) + 631x/6321 ESB2
Dual Intel Xeon 5160
Microsoft Windows 10 Professional (x64) Build 19045.4529 (22H2

  • VM Guest:

Raspberry Pi Desktop.
Debian 11.10 Bullseye
Linux XRCERIUM 5.10.0-15-amd64 #1 SMP Debian 5.10.120-1 (2022-06-09) x86_64 GNU/Linux

/bin/ls: ELF 32-bit LSB pie executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, BuildID[sha1]=00695414aa5413c8667e62c2362d119cb233a504, for GNU/Linux 3.2.0, stripped

  • Hypervisor:

VMware Player 12.5.9 - Most recent version that will run on host's chipset.

Testing (method):

  • VM guest suspended.
  • Pico plugged in to host ready for firmware loading.
  • "flash_nuke.uf2" loaded.
  • Target firmware/CircuitPython loaded.
  • Ejected from host.
  • Connected to host.
  • Test that "copy.py" is R/W via host - Always OK.
  • VM guest opened from suspend.
  • Pico connected to guest from host.
    • Note: Prior to connection to the VM, the icon in the VM tool bar looks like a web cam, not a storage device.
    • Once connected to the VM "Connect (Disconnect from host)" it appears as a speaker icon.
  • "Mu" development environment opened.
  • Attempt to change "code.py" made, via "Mu"
  • Some information gathered from guest.
  • Pico removed from guest (back to host).
  • "Mu" closed.
  • VM guest suspended.
  • Test that "copy.py" is R/W via host - Works for 8.x, fails for 9.x64
  • Pico ejected from host.

Testing (detail):

Version: adafruit-circuitpython-raspberry_pi_pico-en_GB-8.1.0.uf2:
Can write to file system (code.py) OK in VM (Raspberry Pi Desktop Bullseye).

  • "mount" output for Pico:
