Hello
I have problems getting klipper to work on the new SKR e3 turbo.
klippy(5).log

I have this error message: Unable to read tmc uart 'stepper_x' register IFCNT
Once the underlying issue is corrected, use the "RESTART"
command to reload the config and restart the host software.
Printer is halted

please help me

#tx_pin:
#   If using separate receive and transmit lines to communicate with

#   transmit pin. The default is to use uart_pin for both reading and

Remove the line tx_pin:xxx on all tmc

I'm sorry, that was just an attempt, it doesn't work even without this entry.

Are the settings for the flash correct?

It looks like this board has a new "low power standby" feature which might require some pins to be set at microcontroller startup in order for the TMC drivers to work. Someone more knowledgeable than me will need to take a look.

The list of standby pins is here.

It looks like they need to be pulled low during startup if I'm understanding the Marlin PR correctly.

Thank you
How can I control the pins?
Yes, I think the standby feature will trigger this problem

I did it, I entered the GPIO pins of the standby in the make menuconfig and it works!

This also fixed the communication fault for me. To summarize, when building the firmware for the E3 Turbo, the following GPIO pins need to be named in "make menuconfig" to pull them down on startup:

!P.3.26, !P3.25, !P1.18, !P1.19, !P2.13

FYI, it's better to not modify "make menuconfig" and instead add the following to printer.cfg:

[static_digital_output tmc_standby_pins]
pins: !P3.26, !P3.25, !P1.18, !P1.19, !P2.13

Thanks Kevin I'll give that a shot. Can you elaborate at all on why that's a better way? I am still working to get my head around the klipper ecosystem.

@KevinOConnor

Just that it's easier to modify and view printer.cfg.

FYI, I added an example config for the e3-turbe (commit f79187d).
