Compilation error, Marlin

[fdc1]

Hello, an error occurred while compiling Marlin for the Tronxy X5SA printer. I did everything according to the instructions as in the video ( Tronxy to Marlin Updated with new Procedure. - YouTube ).
Tried in Atom and VSCode

Error text:

Either your PlatformIO core is not up-to-date or you’re trying to compile an old Marlin option.

Can you

and retry?

@maxgerhardt

and retry?

Thanks. But it didn’t work out. I will try to do something with Marlin.

You can also try and remove all previous packages and platforms in case something weird was installed.

For that, remove all folders in C:\Users\admin\.platformio\packages\* and C:\Users\admin\.platformio\platforms\* and also C:\Users\admin\.platformio\.cache.

A clen version of all needed packages is redownloaded the next time you hit “Build”.
