3.2.3 Upgrading Boot ROM

During the operation of the device, you can use Boot ROM in the storage device to
upgrade Boot ROM programs that are running on the device.

serious mistakes when upgrading Boot ROM. After the validity check function is
enabled, the device will strictly check the Boot ROM upgrade files for correctness and
version configuration information to ensure a successful upgrade. You are
