4. The Bootloader tool will
automatically initialise if
connected via USB and if
the software is in Bootloader
mode. The text on the
Bootloader form will change
to confirm that
communication is
established (see image
below).
5. Click “Open Hex File” and
navigate to the new
firmware file that needs to
be installed. This will
enable the “Program/Verify”
command button, click this
to install the new firmware.
6. The bootloader will then
proceed to install the new
firmware file. The
bootloader will show a verify
error after the file is
installed. This is caused by
the bootloader not being
able to verify the encrypted
file and is not a problem, the
new firmware file is now
installed.
7. Use the “Reset Device”
command to cycle the
power and disconnect the
bootloader software.
8. You can now disconnect the
your USB lead and re-
establish communications
with the OPC using the OPC
software, this will confirm
that the new firmware file
has been installed correctly
and is ready for use.
9. Check that your laser DAC
settings are returned to the
original setting. See the
main section of the manual
for information on setting
EEPROM configuration.
