Hi everyone,
i’m quite new in this world.
it’s a week since i’m trying to runs TMC5160 on BTT SKR3 but i’m always having back the same issue: “Unable to write tmc spi ‘stepper_a’ register GLOBALSCALER”.

I assume it’s a problem of communication, but i can’t find a solution.
I define all the motors in this way:

[tmc5160 stepper_a]
cs_pin: PD5
spi_software_miso_pin: PE15
spi_software_mosi_pin: PE13
spi_software_sclk_pin: PE14
run_current: 0.800


[tmc5160 stepper_b]
cs_pin: PD0
spi_software_miso_pin: PE15
spi_software_mosi_pin: PE13
spi_software_sclk_pin: PE14
run_current: 0.800


[tmc5160 stepper_c]
cs_pin: PE1
spi_software_miso_pin: PE15
spi_software_mosi_pin: PE13
spi_software_sclk_pin: PE14
run_current: 0.800


[tmc5160 extruder]
cs_pin: PC6
spi_software_miso_pin: PE15
spi_software_mosi_pin: PE13
spi_software_sclk_pin: PE14
run_current: 0.800

Hope someone can help me.
Thanks a lot :slight_smile:
