Mbed: can't upload to nucleo boards

[sstaub]

Using Mbed, when I try to upload I get following output:

I get a failed but the 1. Upload works and the program runs
After them no more upload is possible
It happens with all nucleo boards
platformio.ini:

[env:nucleo_f401re]
platform = ststm32
board = nucleo_f401re
framework = mbed
upload_protocol = stlink

Hello,

This seems to be linked to the gpio_reset issue:

The corresponding pull request has just been merged on official MBED OS repository:
ARMmbed/mbed-os#14032

If you need to resolve this issue right now on latest PIO mbed package, please check this post:

Should be fixed in the latest mbed package. Please run pio platform update ststm32 in the IDE terminal.

No I can upload with the Mbed framework, but with Arduino framework there is no upload via stlink:
