Unable to move stepper motors from Klipper

[slavanyx]

Hi I am getting Unable to write tmc spi 'stepper_x' register GLOBALSCALER error when I try to home steppers on SKR 3 EZ, using EZ5160 drivers

below is my printer.cfg config, pretty standard with minimal changes. Everything boots up, can heat extruder/bed, when trying to home steppers getting this error. Can be related to software spi but since the card is pretty new not much examples on the web

Thank you!

This file contains common pin mappings for the BigTreeTech SKR 3.

To use this config, the firmware should be compiled for the

STM32H743 with a "128KiB bootloader".

See docs/Config_Reference.md for a description of parameters.

check your TMCs, if one is broken you will have that globalscaler
