Sensorless homing with tmc5160 and SKR 1.4T

Does anyone know how I have to setup sensorless homing with tmc5160 and an skr 1.4T? If I home the axis it just moves endless( even with driver_SGT: -64), if I reverse the diag1_pin the endstops are perma triggered, also tried with and without pullup (^). Here's the cfg. I've read somewhere that you need to cut the clk pin
