When enabling MMU2S on SERIAL 3 or 6, the sensorless homing ( X & Y) on a SKR Pro 1.1 with TMC2209 fails.
When home X run, it bumps but don't stop.
Same thing for home Y.
If I disable MMU2S in the configuration, sensorless homing works again.
This setup was working few months ago, but since the last bugfix2.0 I can't make it works.
Maybe it can be the 3rd serial implementation. Don't what to check.
This Printer is a CoreXY

It can be related to SKR Pro 1.1 and/or CoreXY setup
