How should my vanilla LoPy 4 be configured?

[Pugnacious]

OK, I jumped the gun and got my LoPy 4 up & running under Atom only to transfer my old WiPy development library into it.
Can someone point me to what are the default shipping files that come with the LoPy 4 so I can restore it to it's factory state? The LoPy directory in GitHub is from 2016 (: Thanks. What I'm looking for is a directory tree along with what files belong where. #LoPy4

@robert-hh Thanks. I did the os.mkfs('/flash') and then ran Pymate on my phone to re-establish a WiFi connection and reinitialize the chip (repopulating with main.py and boot.py) that I now see in ftp.

@pugnacious The defeault main.py and boot.py are just empty with a comment like:
# Put your own code here
The same for the directories you mention. You can put code of "library style" into /flash/lib, but that's just a place mentioned in sys.path.
/flash/sys and /flash/cert are "special" directories, more like logical devices than file system places, just used for special actions. So ignore them in the first place.

@livius Yes. Inadvertently as to mean "screwed up" by having an old project folder open in Atom a REPL window open talking to the chip and then hitting the Upload button which transferred all the files including updated main.py and boot.py onto my new LoPy. It might not make sense, but yes it happened.

Thanks, the os.mkfs('/flash') did work and gave me a clean directory with nothing in /flash and it appears my old project files are nowhere to be seen.

What directory structure should I be seeing and what files should be there? What I'm looking for is:
Where can I find an original main.py and boot.py? Are these in a current github repository, if so where?
What files need to exist under /flash/lib, /flash/sys, and /flash/cert? where are these and are they important?
Anything else to restore to factory condition?
Thanks for responding.

@pugnacious said in How should my vanilla LoPy 4 be configured?:

inadvertently transferred to the chip?

If you mean to the flash then yes os.mkfs('/flash') is like "format" commad on desktop

[Pugnacious]

@livius Thanks! Will this also eliminate the rubbish files that I inadvertently transferred to the chip?

@pugnacious
there is no something like restore to the factory firmware.
You can check which firmware you have by issuing command

import os
os.uname()

you can only clean flash from custom files by

import os
os.mkfs('/flash')

then your lopy will run as clean

to work with current Pymakr you need to update firmware first:

The LoPy directory in GitHub is from 2016

sources of firmware are under
https://github.com/pycom/pycom-micropython-sigfox
and
https://github.com/pycom/pycom-esp-idf

libraries you can find here
