Firmware Update Error messages
During a firmware update, the following warnings or error messages may be displayed:
The firmware update failed
This message appears when the overall update process failed without any other error message. It is
shown when the updated multiplexer firmware does not report a version message after start-up.
Not a valid firmware file
The file you are trying to open is not a valid firmware file. A firmware file not only ends with an “.mpx”
extension, it also contains a distinct signature that must be present. This prevents you from
accidentally loading the wrong file into the multiplexer.
Unsupported firmware file version
The firmware file version is not supported by MPX-Config. Currently, there is only one firmware file
version but it is not unlikely that in the future new version are developed which require an update of
MPX-Config
.
Firmware file is corrupt
The firmware file is damaged, possible due to an error during download from our website.
The version of the firmware file is lower than the version of the multiplexer. Do you really
want to proceed?
You are trying to update the firmware in the multiplexer with an older version. This is just a warning
and very well possible to do.
Bootloader initialisation failed
When MPX-Config starts the update process, a small program called the Bootloader must be started in
the multiplexer. This message tells you that the bootloader could not be started. This can happen
when you try to update the multiplexer while navigation instruments are connected and sending lots
of NMEA data to the multiplexer. This can interfere with starting the update process. Disconnect or
power down the instruments to prevent this problem.
Firmware file does not match with the multiplexer type
Most firmware files will be compatible with all types of multiplexers. It is however possible that special
firmware is made available which only runs on a specific type of multiplexer. If this message appears,
you apparently are trying to update using a firmware file that is not suitable for your type of
multiplexer.
Bootloader: Erase command timeout
An error occurred when the bootloader tried to erase the old firmware.
Bootloader: Encryption command timeout
The bootloader did not respond to the Encryption command sent by MPX-Config.
Bootloader: Programming timeout
There was an error during programming a section of the firmware image.
Bootloader: CRC command timeout
The bootloader failed to calculate the checksum of the newly loaded firmware image.
Bootloader: CRC error
The calculated checksum of the newly loader firmware image does not match the checksum if the
image file. Apparently there was a communication error between MPX-Config and the multiplexer. You
can try to update again.
Invalid response from bootloader
The bootloader returned an unknown response to a command from MPX-Config.
