Not work on Pyboard (and clones)

micropy-cli version 2.1.0 not work on Pyboard (STM32F405RGT6 MCU) and it’s clones. stubs generation end with errors. On ESP32 work without problems.

micropy stubs create COM8

StopIteration

After physically device disconnect-connect there is stub files visible on filesystem.
Main difference of this boards is internal fs exposed as USB mass storage device. Disabling USB MSD not solve this problem.

Thanks @BradenM, I’m currently using the ESP32 stubs which are indeed very similar. Thanks for all your effort with this development. The intellisense is fantastic.

Interesting , How do you handle the issue that upydev depends on netifaces requires the VS C++ build tools to be installed ? does not that make the threshold to install too high ?
