SKR Mini E3 V3

I'm trying to configure the motherboard Firmware with marlin and visual studio.

In platform.ini the env is default_envs= STM32G0B1RE_btt and in configuration.h the motherboard is BOARD_BTT_SKR_MINI_E3_V3_0

Unfortunaly the firmaware can not be build. I already tried to  copy the stable version firmware variant_MARLIN_STM32G0B1RE.cpp, variant_MARLIN_STM32G0B1RE.h, ldscript.ld, PeripheralPins.c from your link located in the path buildroot/share/PlatformIO/variants to the library directory of our machine in C:\Users\Administrator.platformio\packages\framework-arduinoststm32\variants\STM32G0xx\G0B1R (BCE) (IT) xN_G0C1R (CE) (IT) xN.

But I obtain always the same error:

Executing task in folder Marlin-2.0.x: C:\.platformio\penv\Scripts\platformio.exe run --environment STM32G0B1RE_btt <

Processing STM32G0B1RE_btt (platform: ststm32@~14.1.0; board: marlin_STM32G0B1RE; framework: arduino)

For anyone who culd have the same problem. I fixed it creating the directory C:\Users\Administrator.platformio\packages\framework-arduinoststm32\variants\STM32G0xx\MARLIN_G0B1RE
and inside it I placed the file from the link https://github.com/bigtreetech/Marlin/tree/SKR-mini-E3-V3.0-G0B1/buildroot/share/PlatformIO/variants/STM32G0xx/MARLIN_G0B1RE

Pay attention that the ldscript.ld is saved as a .ld file and not a .ld.text file
