2.10.2 Power-Up Setup Configuration
The RVP902 stores on disk an extensive set of configuration information.
The purpose is to define the exact configuration on startup. The setup
information can be accessed and modified using either the local keyboard
and monitor, or over the network. For multiple radar networks, the
configuration management can be centrally administered by copying
tested “master” configuration files to the various network radars. The
RVP902 has the capability to flash the RVP901 software. This allows
upgrading to new versions, as needed, by the user.
During the boot process, the RVP901 is first loaded with a factory
configurable diagnostic image. The diagnostic image initializes devices
that need initialization, and leaves the board in a reset condition. It verifies
that the RDA software and setup configuration is present and uncorrupted.
Once validated, the diagnostic image boots the RDA application. The
application image runs some basic memory self-tests before starting.
The RDA version can be updated in the field with minimal risk. The
RVP902 software provides a configuration interface. If, for some reason,
the upgrade was interrupted or not completed successfully resulting in an
invalid image, the unit stays in diagnostic mode on the next reboot to allow
the user to recover from the failure. If the RDA software boots, but is
unresponsive, the user may force the unit into diagnostic mode by sticking
a paper clip in the inner most hole (SW1) in the finned side of the
enclosure. After entering the diagnostic boot mode, the user may re-flash
the RVP901 software from the signal processor to recover from a
corrupted image.
The platform provides monitoring of voltage and temperature conditions.
It also monitors the locked conditions of the various PLLs on the FPGA to
verify that the analog and digital clocks on board are in good health.
The RVP902 IP address is user-configurable. The outer most hole (SW2)
in the finned side of the enclosure allows the user to reset the IP address to
10.0.1.254, in the event the user can not remember what was programmed.
For more information about flashing the software and setting the IP
address, see Chapter 3, Hardware Installation, on page 61.
