Describe your issue:
After a long while i wanted to update my printer to latest klipper. It went fine for the Raspberry MCU which i have but on the btt-skr-mini-e3-v2 i ssee following issue:
SD Card Flash Error: argument of type ‘NoneType’ is not iterable

if bus not in bus_enums:
TypeError: argument of type ‘NoneType’ is not iterable
When i look into the enumations object like it’s accessed here klipper/scripts/spi_flash/spi_flash.py at master · Klipper3d/klipper · GitHub i can see that it is missing the bus, only ‘static_string_id’ and ‘pin’ are present:
