The machine displays a message to indicate that
download is complete.
This message appears on the SOM on the
connected PC, as well as on the machine's
operation panel.
If this message does not appear, the download
failed. Try again.
You can also switch from an Ethernet connection
to a USB connection (or the other way around)
and see if that works.
If you still cannot download the firmware, it may
be necessary to change the engine board and/or
the controller board.
