Pin 'PA15' is not a valid pin name on mcu 'EBBCan'

I’m trying to configure an existing BTT EBB36 can module from other printer in my new Voron 0.2 but klipper is not accepting my configuration With error “Pin ‘PA15’ is not a valid pin name on mcu ‘EBBCan’”

Relevant Configuration:

[mcu EBBCan]
canbus_uuid: d05fdfdf7adb

[tmc2209 extruder]
#uart_pin: EBBCan: PA15
uart_pin: EBBCan:PA15
run_current: 0.600    # for LDO 36STH20-1004AHG
stealthchop_threshold: 0
sense_resistor: 0.110

I copyed this configuration from a working configuration in other printer and BTT EBB36 1.2 documentation says it’s the correct pin.

Missing a space between EBBCan:PA15 should be EBBCan: PA15

tryed both ways, several times

Then the klipper firmware is not created for an STM32G0B1

According to the github link in post #1, the UART pin is PA13, not PA15

@EddyMI3D
V1.0 PA13
V1.1 & V1.2 PA15

In deed, but that is another site…

Directly from BigTreeTech the manufacturer.
More than likely the firmware was complied with the wrong STM32.

The V1.1 & 1.2 have the G0B1.

always post klipper.log, it tells the truth

A post was split to a new topic: LGX-Lite extruder on Ebb42

Possible, yes … But i Have done a roll back in klipper (like 50 commits or so) through kiauh and it worked. If it was a a wrong STM32 it should have not worked at all.

Made an update now and all seems ok.
