2.11 Firmware upgrade
The board can store two firmware versions, called STD and BKP respectively; at Power
On, a microcontroller reads the Flash Memory and programs the module with the
firmware version selected via the J6 jumper (see § 2.6.2), which can be placed either on
the STD position, or in the BKP position. It is possible to upgrade the board firmware via
USB, by writing the Flash: for this purpose, download the firmware package available at:
http://www.caen.it/csite/CaenProd.jsp?parent=12&idmod=466
.
The package includes the new firmware release file:
N957CTL_revXY.rbf
For upgrading the firmware, utilize the upgrade program situated in the folder described
in paragraph in § 4.1.1.5; open a DOS Shell, then launch:
N957Upgrade -Ifilename (filename= upgrade input file).
N.B.: it is strongly suggested to upgrade ONLY one of the stored firmware
revisions (generally the STD one): if both revision are simultaneously updated, and
a failure occurs, it will not be possible to upload the firmware via VME again!
2.11.1 N957Upgrade command parameters

The parameters format is as follows:
