M8P V2.0 config Problems.

Hi there

I recently bought a BTT M8P V2.0 with a CB1 and the EBB2209 Can Board because i want to switch to CAN and the umbilical Mod.
Installing Klipper, programming EBB Board all works perfect with the tutorials i found but now i had a Problem with the Steppers.
I wanted to Home the Printer and then i get the Error: Unable to read tmc uart 'stepper_x' register IFCNT

After a bit of digging i think i had the wrong pins in my printer config, but im not sure how to fix it or which pin is right or not.
Can someone help me with this?

I added my printer.cfg as txt file.

First of all. I am a newbee that just got my RP2040 to communicate with the M8P (version 1.1) . in my printer.cfg file under the MCU i have an additional statement under the canbus uuid which is "canbus_interface: can0". I think It tells klipper where to find the connection to the uuid device...
