Gpy crashing on firmware update

[ljmerza]

Please include the following information when submitting a bug report:

• The Pycom board you are using (e.g. WiPy 2.0, LoPy). Gpy
• The firmware version you are using. You can get it by executing the following Python code at the REPL: 1.20.2.r4

  import os
  os.uname()

  The output will look similar to this:

  (sysname='LoPy', nodename='LoPy', release='0.9.4.b1', version='bc42ea7 on 2016-11-14', machine='LoPy with ESP32')

  getting core dump:

not sure what this even means?

It seems there is a problem with the filesystem while you're trying to upload the micropython project (or are you specifically trying to do a firmware update?). Could you perhaps try os.fsformat('/flash') before trying again? Be aware that will clear the filesystem.
