In this example, instead of the new firmware, the old firmware V1.00 is being simply re-flashed.
Now the user can add any comments to the flashing operation in the
Flashing Comments
field.
They will be stored in the
Bootloader Information
group after flashing.
The user can also check the
Erase All ECU Flash Memory
flag to erase all configuration
parameters related to LIN set by the old firmware and force the converter to load the LIN
default values after flashing the new firmware. This operation, used in other products to reset
all configuration parameters kept in the flash memory to their default values, has no effect in
this product. This is because all the configuration parameters of the converter other than LIN
are stored in a separate EEPROM memory.
Otherwise, the default LIN values will be set only to the new configuration parameters
introduced in the new firmware. The old configuration parameters will keep their original values
unless otherwise is stated in the user manual.
Select the
Flash ECU
button to start flashing. A reminder that the old application firmware will
be destroyed by the flashing operation will appear. Press
Ok
to continue and watch the
dynamics of the flashing operation in the
Flashing Status
field. When flashing is done, the
following screen will appear prompting the user to reset the ECU, see Figure 49.
Figure 49. Flashing New Firmware. Final Reset.
Select
Yes
and see the ECU running the new firmware, see Figure 50. This will indicate that
the flashing operation has been performed successfully.
