Try the 'absolute newest' build from "S3" https://circuitpython.org/board/feather_stm32f405_express/
7.0 .0 alpha4 did not work for me either (as you described) but the latest build does work

[water5]

7.0.0-Alpha.4 (2021-07-15 github custom build) on 'STM32F411CE Black Pill' works fine.

[jerryneedell]

Ah - I found that 7.0.0 Alpha.4 does actually boot and mount but it took quite a long time -- maybe 20 - 30 seconds after pressing the RESET button
I am accessing it from a Linux computer (Ubuntu 20.04)

I see the same, with #5172 (just in case it was a tinyusb bug that was subsequently fixed):

What do y'all have in code.py? I bisected the problem I was seeing to the merge of #3191 (between beta.2 and rc.0) but it went away after moving my code.py out of the way. code.py contained some code to use canbus, but there was no working bus.

The code I had was:

import struct

import board
import canio
import digitalio

# If the CAN transceiver has a standby pin, bring it out of standby mode
if hasattr(board, 'CAN_STANDBY'):
    standby = digitalio.DigitalInOut(board.CAN_STANDBY)
    standby.switch_to_output(False)

# If the CAN transceiver is powered by a boost converter, turn on its supply
if hasattr(board, 'BOOST_ENABLE'):
    standby = digitalio.DigitalInOut(board.CAN_STANDBY)
    standby.switch_to_output(True)

# Use this line if your board has dedicated CAN pins. (Feather M4 CAN and Feather STM32F405)
can = canio.CAN(rx=board.CAN_RX, tx=board.CAN_TX, baudrate=250_000, auto_restart=True)
# On ESP32S2 most pins can be used for CAN.  Uncomment the following line to use IO5 and IO6
#can = canio.CAN(rx=board.IO6, tx=board.IO5, baudrate=250_000, auto_restart=True)
listener = can.listen(matches=[canio.Match(0x408)], timeout=.9)

old_bus_state = None
old_count = -1

while True:
    bus_state = can.state
    if bus_state != old_bus_state:
        print(f"Bus state changed to {bus_state}")
        old_bus_state = bus_state

    message = listener.receive()
    if message is None:
        print("No messsage received within timeout")
        continue

    data = message.data
    if len(data) != 8:
        print(f"Unusual message length {len(data)}")
        continue

    count, now_ms = struct.unpack("<II", data)
    gap = count - old_count
    old_count = count
    print(f"received message: count={count} now_ms={now_ms}")
    if gap != 1:
        print(f"gap: {gap}")

.. and I can go all the way back up to 7.0.0-alpha.6 with no code.py and all is well.
