MicroPython crashes when accessed using mpremote

[andypiper]

MicroPython identifies itself as MicroPython afceb56-dirty on 2022-06-04; TiDAL with ESP32S3 when connected to in the REPL.

I can run mpremote devs to successfully list the attached device, and I can use mpremote connect mpremote connect /dev/cu.usbmodem1234561 (macOS) to connect to the REPL if no other apps (Thonny or Chrome WebSerial) are attached, but trying to run mpremote commands e.g. mpremote connect /dev/cu.usbmodem1234561 ls fails with the following trace (the board reboots to the EMF logo and locks up at this point)

$ mpremote connect /dev/cu.usbmodem1234561 ls                                 git:(master|)
Traceback (most recent call last):
  File "/opt/homebrew/lib/python3.9/site-packages/serial/serialposix.py", line 575, in read
    buf = os.read(self.fd, size - len(read))
OSError: [Errno 6] Device not configured

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/opt/homebrew/bin/mpremote", line 8, in <module>
    sys.exit(main())
  File "/opt/homebrew/lib/python3.9/site-packages/mpremote/main.py", line 478, in main
    pyb.enter_raw_repl(soft_reset=auto_soft_reset)
  File "/opt/homebrew/lib/python3.9/site-packages/mpremote/pyboard.py", line 352, in enter_raw_repl
    data = self.read_until(1, b"raw REPL; CTRL-B to exit\r\n")
  File "/opt/homebrew/lib/python3.9/site-packages/mpremote/pyboard.py", line 303, in read_until
    data = self.serial.read(min_num_bytes)
  File "/opt/homebrew/lib/python3.9/site-packages/serial/serialposix.py", line 581, in read
    raise SerialException('read failed: {}'.format(e))
serial.serialutil.SerialException: read failed: [Errno 6] Device not configured

I'm relatively certain this is not supposed to happen (I do Mpy development with other ESP32 boards, using MicroPython v1.18+ from GitHub nightlies).

Is there a board definition file / config I can use to build the firmware in the current MicroPython source tree?

mpremote is untested. If it has an option to disable soft reboot, try that.

No, sorry. You need to build using this repo.

Have been trying to use the docker images but seems like we'll be hitting docker/for-mac#900.
