Unable to read tmc uart 'extruder' register IFCNT #36

Replaced an EBB36 with the SB2209 and getting this error when I try to extrude.

"Unable to read tmc uart 'extruder' register IFCNT"

Extruder config (I changed the MCU name from EBBCan to can0)

EXTRUDER

[extruder] step_pin: can0: PD0 dir_pin: !can0: PD1 enable_pin: !can0: PD2

Update value below when you perform extruder calibration

If you ask for 100mm of filament, but in reality it is 98mm:

rotation_distance = * / 100

22.6789511 is a good starting point

I'm experiencing the same error and I see you closed the issue... What was the fix?

It's pretty silly. I thought I bought the version with the 2209 driver, but turns out it was the 2240. Changed the configuration in Klipper and it worked fine.

🤦 I did.... THE SAME EXACT THING! 🤦
