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 that 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.
