6 years ago When exactly do you get the error
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OSError: [Errno 19] ENODEV? Just waiting in the REPL, or executing some command?

6 years ago e.g.: sending a file with thonny results in:
>>> %upload main.py /main.py
Traceback (most recent call last):

>>> open("main.py", "r").read()
'#test'I also try to send files via rshell doesn't work:
+ rshell -p /dev/ttyUSB0 rsync -v . /pyboard
Connecting to /dev/ttyUSB0 ...
Adding /pyboard/crossbar_demo.py
timed out or error in transfer to remoteIf i add --debug i can see that the timeout appears in:
----- About to send 2174 bytes of code to the pyboard -----
def recv_file_from_host(src_file, dst_filename, filesize, dst_mode='wb'):
...How can I better find out where the problem appears?

6 years ago Sorry, I've never used thonny, rshell was reported to work, but I'm not using it. I can only recommend to use FTPServer for file transfer.

6 years ago Great idea. I will test it. But it would be interesting what happens in thonny. I have use ist with baseline micropython
EDIT: I also report it here: https://bitbucket.org/plas/thonny/issues/540/upload-doesnt-work-with-lobo-micropython

6 years ago Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OSError: [Errno 19] ENODEVComes from: open("/foo_bar.py", "wb")
It will work, if i change the file path from '/foo_bar.py' to 'foo_bar.py'

6 years ago The root of the internal FS is /flash/.
So you have either to use the full path "/flash/foo_bar.py" or the relative to your current directory "/foo_bar.py".

6 years ago OK... Then this can be closed... But: Is it possible to change the OSError: [Errno 19] ENODEV message to something more appropriate? e.g.: OSError: [Errno 19] Target not writable!

6 years ago ENODEV is a standard error code (OS error) which means "No such device" and will be issued if some requested device (which may be file, but also something else) cannot be accessed.
It would be impractical to generate more descriptive messages for all possible cases.

6 years ago Ah ok! Good to know...
But can be ENODEV renamed to No such device ?
I have a ODROID-GO and whant to use microPython...
Specs from https://github.com/hardkernel/ODROID-GO-MicroPython :
So i guess esp32_psram_all is the best choice?!?
I made this:
MicroPython_ESP32_psRAM_LoBo/MicroPython_BUILD/firmware/esp32_psram_all$ ../flash.shAnd the REPL works. But i get errors like:
The boot output is:
