Bug Description

Just got a tevo tornado in and wanted to make it silent. Got a SKR 1.4 turbo with 2209 btt and a bltouch. After countless sleepless nights and flashing firmware x100 I am still not there.

It can home x and y, but when homing z in runs into the bed. the bltouch does nothing! I am sure its an easy fix but I just can't find it after working on the code for multiple days in a row. I just want to use it not fix it.
My Configurations

[drive.google.com]

Steps to Reproduce

Turn on printer
G28
G29

Expected behavior: home x, y then z. Z with BLtouch

Actual behavior: homes x and y, then goes to the middle and runs down into the bed until the endstop is triggered. If you follow the g29 it sending probe error.
Additional Information

[drive.google.com]. the bltouch does nothing! I am sure its an easy fix but I just can't find it after working on the code for multiple days in a row. I just want to use it not fix it. Can't attach a config file. How to?Please help

Hello,

are you set the jumper for TMC2209 to UART or SPI ?
SKR 1.3 and 1.4 are like the same set
