Unable to read tmc uart 'extruder' register IFCNT
Once the underlying issue is corrected, use the
"FIRMWARE_RESTART" command to reset the firmware, reload the
config, and restart the host software.
Printer is shutdown

Research direction
Start with the BTT Expansion Module V1.0 and Octopus Pro pinout documentation, then review the Klipper TMC UART configuration for the M2 extruder driver and the reported wiring. Verify the correct UART and RX connections and reproduce the IFCNT read failure; done means the extruder register is readable and the printer no longer shuts down.
