Firmware downloading
(continued)
Note 2: By using the LOADFW command without the UPGRADE option,
the firmware downloads to the DMS system.
XPM Firmware Loader Robustness CM Component disables the firmware
option of the LOADPM command. A message is output to the user if the
firmware option of the LOADPM command is used. This message states
this option is not supported and to use the LOADFW command.
Loadfile verification
Integrity checks are performed on the firmware for loadfile accuracy. A
loadfile record length check ensures the file is a firmware file before
submission to the XPM. If the record length is not 54, a message is output
to the user and the LOADFW command fails.
Another accuracy check is a 32-bit cyclic redundancy check (CRC) along
with a 16-bit checksum. The CM sends a validation message to the XPM to
verify the accuracy of the firmware load. The XPM extracts the CRC and
checksum that is in the firmware load. The XPM computes the CRC value
and the checksum. The XPM compares the computed and extracted values
to see if the values are the same. The XPM sends the result of the
comparison to the CM.
To verify the firmware load enter the following command at the MAP
display terminal:
>QUERYPM CNTRS
Firmware upgrade
After loadfile verification, the XPM can be upgraded to the new firmware.
To upgrade the firmware use one of the following command string sets:
>BSY PM
>LOADFW PM UPGRADE
>RTS PM
or
>BSY UNIT unit_no
>LOADFW UNIT unit_no UPGRADE
>RTS UNIT unit_no
or
>BSY INACTIVE
>LOADFW INACTIVE UPGRADE
>RTS INACTIVE
