TMC2130 - Marlin 2.0.9.5 - RAMPS 1.4 - Error: All HIGH (6 replies)

Hello:

I'm trying to get my shiny new TMC2130 drivers configured with SPI on my RAMPS 1.4 controller. I'm installing Marlin 2 for the first time with VS code and Platform.io. I've gone through the configuration with single Z-axis. M122 yields this:

I'm using the default configuration pins for RAMPS 1.4 (pins_RAMPS.h)

  #define X_CS_PIN                            53
  #define Z_CS_PIN                            40
    #define TMC_SW_MOSI                       66
    #define TMC_SW_MISO                       44
    #define TMC_SW_SCK                        64

Any help is appreciated.
