5.1.3
Transitioning to Firmware Update Mode
The module transitions to firmware update mode for any of the following reasons:
1.
Winloader has commanded the module to enter firmware update mode. This is
normal when a firmware update has been initiated from Winloader.
2.
The ECM850 does not have a valid firmware image at power-up. The ECM850
performs checks to determine the firmware image is valid and has not been
corrupted before it begins execution. If the validation fails, firmware update mode
is activated until a valid image has been stored.
For more information about firmware update mode and using Winloader, please see
Chapter 2:, Installation.
