It is impossible to use its board, it has potential, but it remains to polish things

How can I fix this bug in Marlin bugfix-2.x.x?

Error: Unknown environment names 'MKS_ROBIN2'.

It is impossible to compile for this board.

There is also no pin reference so they PINs, be redirected for various uses. PLEASE RELEASE IT.

Marlin have not support MKS Robin2, because FSMC no display. I suggest you use Robin2's own firmware for now
