The firmware update leaves Device’s settings intact. You will not damage the Device in the event of power
failure or any other shutdown at any state of firmware update procedure.
To update Device firmware, you should copy the update file (with .BIN extension) to the Device’s port:
copy /B UUPDATE.BIN COM3
cp UUPDATE.BIN /dev/cu.usbmodem00090001
cp UUPDATE.BIN /dev/ttyACM1
We used the same port names above, as were used in the examples in chapter III.
File uploading takes 3-10 seconds, during this time Device’s LED will be off. The Device informs
about upload result with the following LED signals (three fast flashes in one second):
• Green, green, green.
File is successfully uploaded to Device’s EEPROM.
• Red, red, green.
Device already contains firmware of this version.
• Red, green, red.
File header is correct, but uploaded file is corrupted.
If the Device produces no special signals after copying the file, it means that the file was not recognized
by the Device as a firmware update file. This may be caused by copying a ZIP archive with firmware update
instead of the firmware update BIN file.
After successful upload followed by three green signals, the Device reboots to pass control to the bootloader.
The bootloader will make some additional checks, and if uploaded file is correct, the Device’s LED
will be turned off for 5-15 seconds, and a 10 second series of green and red flashes after that will indicate
that firmware is updated. After that, the Device returns to a normal operation. If the file is incorrect,
the bootloader returns control to the firmware program without any visual cues.
