Description
I have an ebb36 connected to a u2c.
All fans and end stops work.
heater and thermistor works.
The only thing I can’t get working is the extruder tmc2209. Using the config from the GitHub with PA15 as the pin. I always get unable to read tmc uart.
I’ve tried setting the uart address to 0. Tried all combinations of fixes online.
Completely turned off power to the main board and the raspberry pi, including to the canbus boards. Still no luck
when using the extruder on the main board pins using a tmc2209 driver it all works. The x y and z also work. So it’s just the canbus tmc2209 I can’t get to work.
Any ideas?

Research direction
Start with the EBB36 GitHub configuration using PA15 and the reported UART address settings, then compare them with the working TMC2209 setup on the main board. Done means the extruder TMC2209 on the CAN-connected EBB36 can be read successfully, matching the other working drivers.
