BIQU BX MCU protocol error

My Klipper is up to date!!

“Your Klipper version is: v0.12.0-114-ga77d0790

It seems to me that I have to update (Host MCU MCU-like functions on the SBC)

"MCU(s) which should be updated:

CB1: Current version v0.11.0-122-ge6ef48cd"

but I don’t know how!!

I re flashed my printer board via USB

Up-to-date MCU(s):

mcu: Current version v0.12.0-114-ga77d0790"

error persists
