FLASHING NEW FIRMWARE
When the new firmware becomes available, the user can replace the converter 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 45.
Figure 45. Bootloader Activation. First Step
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 46.
Select
Yes
.
After automatic reset, instead of
AX140610, LIN - CAN Protocol Converter with PWM Output
,
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 ready to accept the new firmware.
Figure 46. Bootloader Activation. Final Reset
All the bootloader specific information: converter hardware, bootloader details, and the
currently installed application firmware remains the same in the bootloader mode and the user
can read it in the
Bootloader Information
group screen, see Figure 47. The information can be
slightly different for different versions of the bootloader.
