Firmware for SKR 2.0?

[huguesdup]

Description

I have an SKR 2.0 Rev B in my B1 with TMC2209 stepper drivers.
I also added a Relay V1.2 for the auto shut down and a double Z-axis (with another stepper for the double z-axis). I did all the changes needed concerning those two in the .h files from the files provided and I already tested them. However, I'm not able to build the firmware with the "Auto Build Marlin" module from VScode...

The line I wrote for the board in configuration.h is the following:

// Choose the name from boards.h that matches your setup
#ifndef MOTHERBOARD
#define MOTHERBOARD BOARD_BTT_SKR_V2_0_REV_B
#endif

This is the message I have when I try to build it :

What should I do with that? Does anyone have tried to upload Luke's firmware on an SKR2.0?
