Arduino for STM32

recently i started learn stm32f407vgt6 with arduino core, then i want to try make my own variant, i have read this on manual https://github.com/stm32duino/wiki/wiki ... 28board%29, but on generated variant files section, i don't know how to generate this file, then.
based from this repo https://github.com/RickKimball/vendor, i can generate use python script called

genpinmap_arduino.py

like explained in https://github.com/stm32duino/wiki/wiki/genpinmap, but after searching on google i found that script has change to

stm32variant.py

on https://github.com/stm32duino/Arduino_C ... /CI/update.
then after try to run that script i got this result

Platform is Windows

Cube Mx seems not to be installed or not at the specified location.

Please check the value set for 'CUBEMX_DIRECTORY' in 'variant_config.json' file.

so where i can place

variant_config.json

or how i can use the new script

stm32variant.py

??

thanks for any help

You don 't need ro generate generic files. They are already generated. Look in variant folders.

i got it, iam newbie sorry for stupid question.
thanks
