Automatic BusEngine and Firmware Updates
BusEngine and Firmware updates often need to be performed when you update the
SASSuite software. These updates can be performed automatically or manually. Both
processes are described.
Updating
the
BusEngine
The BusEngine core is the heart of the LeCroy SAS Analyzer. Using FPGA technology,
it incorporates both the high speed recording engine and the configurable building blocks
that implement data/state/error detections, triggering, capture filtering, external signal
monitoring, and event counting and sequencing. Both the BusEngine program and the
Firmware that manages the internal microcontroller are fully field updateable.
Within a new software release, it may be necessary to update the Analyzer’s BusEngine
hardware for proper operation. The Readme file lets you know if this is necessary.
Updating
the
Firmware
Within a new software release, it may also be necessary to update the Analyzer’s
firmware for proper operation. The Readme file informs you if this is necessary.
Automatic
Updates
When the SASSuite software is updated, the software may become incompatible with the
BusEngine and Firmware. If a recording is attempted, SASSuite displays an error
message and then automatically begins an update process for the BusEngine and
Firmware.
To perform an automatic BusEngine and Firmware update, follow these steps:
Step 1 If needed, update the SASSuite software, following the steps
outlined in "Software Updates."
Step 2 Turn on the Analyzer.
Step 3 Select Start > Record from the menu.
Because the BusEngine and/or the Firmware are incompatible with the
current SASSuite software version, an error message appears showing
your current versions and indicating what versions you need to install.
