Upgrade FAILED
If the connection is unreliable and the Bootloader cannot communicate with the Lightware
device, then the “Upgrade failed!” warning messages appears.
The Bootloader retries the transmission 3 times. If it doesn’t succeed, then the upgrade
procedure will have FAILED. In this case exit the Bootloader, try to establish a reliable
connection with the Lightware device and repeat the upgrade process. It may happen that
when you try to find the device again, the Available devices window will only show the IP
address of the Lightware device but not the device type and serial number. The reason for
this is that the Lightware device may still be in bootload mode and the controllers cannot
send any information about themselves. You can still double-click on the IP address and
the Bootloader will establish the connection.
No controller selected to upgrade!
If you didn’t check any checkboxes left to the controller types then the “No controller
selected to upgrade!” message appears. Click at least one of the checkboxes before you
click on the UPGRADE SELECTED FIRMWARES button.
The controller was not upgraded
Make sure that the checkbox next to the controller type is checked before you click on the
UPGRADE SELECTED FIRMWARES button. These checkboxes enable the firmware
upgrade on the different controller types.
An invalid file has been selected
The Bootloader checks if valid firmware files have been selected for the controllers. If an
invalid file (not firmware file) has been selected, then the “WARNING! Upgrade failed:
Invalid checksum“ warning messages appears.
Please select a valid firmware file.
Firmware selected for the wrong controller
If an otherwise valid firmware file has been selected but for the wrong controller, the
“WARNING! Invalid controller type info for MX16x16DVI-Plus” warning message
appears.
Please select the appropriate firmware file for the controller.
Corrupt firmware file
If the correct firmware file is selected for the controller but it somehow became corrupted
(the checksum is incorrect), then the “WARNING! Upgrade failed: Invalid checksum.
Invalid controller type info for MX16x16DVI-Plus. Invalid hardware info for
MX16x16DVI-Plus.” warning messages appear.
Please contact your local sales representative or Lightware Support Team at
support@lightware.eu and ask for the correct firmware files.
