5 FLASHING NEW FIRMWARE
When the new firmware becomes available, the user can replace the inclinometer firmware in
the field using the unit embedded bootloader. The firmware file can be received from Axiomatic
on request.
To flash the new firmware, the user should activate the embedded bootloader. To do so, start
the EA and in the
Bootloader Information
group screen click on the
Force Bootloader to Load
on Reset
parameter. The following dialog will appear, see Figure 33.

For bootloader versions 1.xx…3.xx, and 4.xx, originally shipped with older versions of the application
firmware, the user should request a special application firmware file compatible with the installed
bootloader version
to upgrade the inclinometer firmware. The bootloader version can be found on the
Bootloader Information group screen.
The EA will prompt the user to change the
Force Bootloader to Load on Reset
parameter flag
to
Yes
. This will automatically activate the bootloader on the next ECU reset. After accepting
the change, the next screen will ask the user if the reset is actually required, see Figure 34.
Select
Yes
.
After automatic reset, instead of
AX06080x, Tri-Axial J1939 CAN Inclinometer
, the user will
see
J1939 Bootloader
ECU in the
J1939 CAN Network
top-level group in the EA. This means
that the bootloader is activated and is ready to accept the new firmware.
