Cannot create stubs on WiPy

[JonathanVusich]

I tried creating stubs for my WiPy, but got this error message at the end. Any ideas on what may cause this?

I have the same error when running against on an STM32WB55 with a daily build of 1.12, running on Windows 10.

I suspect the issue is that the source path for the copy looks incorrect on this platform when fed into rshell. Using rshell and directly connecting to the device:

firmware> ls /pyboard/stubs
Cannot access '/pyboard/stubs': No such file or directory
firmware> ls /flash/stubs
pyboard_v1_12/
firmware> ls /pyboard/flash/stubs
pyboard_v1_12/

Note that /pyboard/stubs is invalid but flash/stubs or /pyboard/flash/stubs seem correct.

Dirty hack/workaround...modify pybwrapper.py:63 (installed here: [virtual-env]\Lib\site-packages\micropy\utils\pybwrapper.py) from:

pyb_path = f"{self.pyb_root}{_path}"

to

pyb_path = f"/flash/{_path}"

micropy stubs create [COMX] will then successfully complete.

A more correct solution appears to be to modify the return of rsh.find_serial_device_by_port() or pyb_root().

This worked for me on the stock pyboard 1.1 with 1.13 firmware and windows 10.

Interesting as V1.13.0 has a [bug] (https://github.com/micropython/micropython/issues/6493) that prevents the subbing process to work. Are you sure that it was not a nightly build 103 or later?

If you need the stubs for 1.13.0-103 you can grab a copy at https://github.com/josverl/micropython-stubs
