Marlin does not compile for SKR Mini with TMC2209 (1 reply)

Hello!

I'm building a pen plotter machine, very simple 2 axes, 3 stepper motor (I have 2 X). So basically all 3d printer function undefined.
When I'm compiling Marlin I get the following error:

Marlin\src\module\stepper\../../inc/../pins/pins_postprocess.h:566:21: error: 'E0_SERIAL_TX_PIN' was not declared in this scope; did you mean 'X2_SERIAL_TX_PIN'?

I have checked the SKR Mini v2 config files and I couldnt figure out where is this, what it should be set to, where it should be set to.
The conf_adv.h does mentions the following on line 2798:

Quote

Set *_SERIAL_TX_PIN and *_SERIAL_RX_PIN to match for all drivers
on the same serial port, either here or in your board's pins file.

config.h
config_adv.h

error log

Any suggestion welcome
