Now your booting log looks completely correct.
Regarding SSTP (Snapmaker Simple Transformation Protocol) - see official articles about hardware:
Controller <-> HMI
The Snapmaker 2.0 controller has two CAN buses - one available on the Add-on 3 connector (4pins) - known as CAN 1 - is used to communicate with additional devices such as Enclosure, Air Purifier, Emergency Button.
If you don’t have any of these devices attached to Add-on3, the message “No module on CAN1!” is completely correct.
The CAN 2 bus (available on all 8-pin connectors) is used for communication with linear modules, rotary module, Toolheads.
