Description

Tmc connection error. I just turned on my printer today after it's been working perfectly for the past 2 weeks, and i suddenly get bombarded with this error. all the steppers still work, and pronterface says all my drivers are "ok"

Steps to reproduce

apparently just use the btt skr mini v2 for 2 weeks.

Expected behavior no errors.

Actual behavior errors.

Additional Information

in marlin mode it says "tmc connection error" and in tft mode it says "all low" it also refuses to start up in marlin mode when I start the printer.

Edit: I have disabled eeprom_settings and the error has disappeared. but this also means I cannot save settings, so I cannot keep it disabled.

any idea of a fix?

By chance, you connect the USB cable before turning on the printer?

Usb was never involved. I updated the motherboard directly from sd card. (its a btt skr mini v2)

as of right now the error is gone.... unless I set my y stepper driver current below 450mA and it disappears when I set it anywhere above that current... but even when I get that error everything works perfectly and both the terminal on the tft35 I have as well as pronterface says my drivers are ok.
