This is how it looks for me on linux:

Thanks!
I figured out some things meanwhile, so sharing in case anyone needs it or search for it:

to flash the newest version of micropython, use the tool from https://github.com/wemos/w600tool.git and not from where the doc say.
run it like this: another option to connect, probably not as good as the one suggested above is:

and another, probably stupid question... All the docs and tutorials show using micropython in console mode. How do I actually load a program to the w600 to be executed when its turned on?

If it has a filesystem, I assume it will execute boot.py and main.py when it starts, like the other ports. (See docs, it looks like they’re only mentioned on port-specific pages.) If not, there is no way apart from building your own firmware. Although you may have trouble getting the files there if the usual tools for that don’t work. (Does it have WebREPL?) In the worst case, you can always type in file writing commands on the REPL.

It does not show in lsblk on my linux, alas
I don't think it has webrepl installed but I am a bit confused about the webrepl concept. If anyone managed to actually load files on it, I would be happy to hear how.
Thanks!

I used a hacked up pyboard.py to load files, it has a filesystem in flash like all the other MP boards.

some more information.....
after connecting the w600 to the lan, use sta_if.ifconfig() to find your ip address
run ftp server by :
import w600
w600.run_ftpserver(username="root", password="root")
you can now upload your files!

https://gist.github.com/aerialist/528b4 ... 4bc77f5289 was a very usefull resource

my 2c on that board:
1. get w600tool.py from Volodymyr at https://github.com/vshymanskyy/w600tool
- I run my as "python3 w600tool.py <...etc>"
2. always have board connected to wifi or ap activated with ftp server running (I use easyw600.ftpserver()) and have time.sleep_ms(1) in the main loop
- by doing that you'll have ftp access to the board and will be able to replace main.py

Ctr+c, Ctr+d doesn't work when the main loop is running.

In my opinion uPyCraft , at the moment, is the only IDE that can be easily used with the new W600-PICO board and I am using it( not only). You can load and check script on the Editor area, load(*) script from the board in the Editor area and download script from the Editor to the board.

Anyway, with the Windows yPyCraft version V1.1, also without the capability of loading the board code from the GUI device tree, a workaround is to load in the uPyCraft REPL shell the onboard upython code using
>>>print(open('<filename.py>','rU).read()) and the cut and paste it in the Editor area.

To download a new firmware we need to use the Volodymyr Shymanskyy w600tool ( Python or Windows version) that can be downloaded from github.

As in the board specs the available flash is 1MB but what's more important to know is the available free flash size that we can use to store our micropython scripts.
To be short ( if I am right) I have found that we have a total of 63 blocks of 512 bytes of available flash size(about 32k) with 58 of them free (29k) for our scripts storage ( 5 are used by the default storage including. 3 dir - lib-sys-cert- and the boot and w600easy files).
Clearly a lot af flash is used to store the firmware wm_w600.fls of 528 kBytes).
Until now the reason of the flash deficit is unknown to me.
I have tested the same script with an ESP8266 board. having 4MB flash founding an available free flash around 3.5MB that is a reasonable value.


# free flash size micropython script
import uos, w600
def run():
files_space = 0
for i in range(len(uos.listdir())):
if len(uos.listdir().split('.')) < 2:
a= uos.listdir()
print("Dir:{} bytes:{}".format(a,uos.stat(a)[6]))
files_space = files_space + uos.stat(a)[6]
else:
a = uos.listdir()
files_space = files_space + uos.stat(a)[6]
b = uos.listdir().split('.')[0]
print(" File:{} bytes:{}".format(b,uos.stat(a)[6]))
s = uos.statvfs(uos.getcwd())
print('Root Dir : '+ uos.getcwd())
print(s)
print('ESP flash size : '+ str( w600.flash_size()))
print('Flash avl size : '+'{0} bytes'.format((s[0]*s[2])))
print('Free flash size : '+'{0} bytes'.format((s[0]*s[3])))
print('Used flash size : '+'{0} bytes'.format((s[0]*(s[2] - s[3]))))
print('Stored files size : '+ str(files_space))
==================================

(*) with the python version - because the WM600-PICO root is '/flash' - to be able to load/run script from the uPyCraft device tree some changes to the python code in uPyCraft.py are required.
