How the motherboard updates the firmware

Marlin: Copy the compiled firmware or the firmware downloaded from the BIGTREETECH GitHub website to the TF card (note that the format must be firmware.bin), then insert the TF card into the motherboard, power on the motherboard, and wait for 5 -10 seconds, remove the TF card from the motherboard, and check whether the firmware name in the TF card has become uppercase. If it becomes uppercase, it means the firmware has been successfully updated.

Klipper: Compile and generate the klipper.bin file in the terminal and rename it to firmware.bin, and then update the firmware according to the above operation.
