is broken in MbedOS 6.6

I can’t make the script provided with MbedOS 6.6.0 work while the one provided by mbedOS 6.1.0 works.

  • MbedOS 6.6.0
  • Windows 10 20H2 64 bits
  • Python 2.7.14
  • option -m STM32 (as recommended by -h)

C:\Users\lluis\Downloads\mbed-os-mbed-os-6.6.0\mbed-os-mbed-os-6.6.0\targets\TARGET_STM\tools>python.exe -m STM32

Script version 1.19

I am sorry, I am verifying script with only python 3…
If you find a way to keep both python version compatibility, I will be happy to review the pull request!

Python 2.7.14 has been released in sept. 2017. Python 2 has been deprecated since January 1st 2020.

It is highly encouraged to upgrade to Python 3, with which the script will work out of the box.

Fair enough! I normally don’t use python so I was using the one that was installed by Mbed CLI.

I’ve just installed python 3.9 and it works :slight_smile:



Glad you did! :slight_smile:
