Firmware images
The BC840-MC has two firmware storage areas: a fixed image area and an upgrade image
area. The fixed image area contains the original factory version of the firmware. This cannot
be erased. The upgrade image area is usually empty upon factory release.
If the existing firmware in the BC840-MC is to be replaced, a new version can be written to
the upgrade image area. There, the new image resides in erasable (flash) memory.
An upgrade image can replace an existing upgrade image written to the device at an earlier
upgrade. It is essential that the upgrade image is compatible with the BC840-MC.
