Erase User Data Utility
A utility to erase all directories and files in the UserData directory is available.
After the flash memory is erased, the boot process returns the UserData
directories and files to the state as shipped from the factory. The System
Information screen indicates the time and date of the most recent erase.
See Chapter 8 for instructions on executing the Erase User data utility.
Error Log
See Chapter 8 for instructions on viewing the error log.
The error log is cleared each time the analyzer is powered off.
Generally, an entry in the error log is created whenever an error message is
displayed.
EXAMPLE: Attempting to set the frequency to a value of “.” (a decimal point),
will generate an entry in the error log.
Firmware Upgrades
Firmware upgrades are available on the Internet. Refer to instructions in the
“Update FieldFox Firmware” section of the FieldFox User’s Guide for details.
See Chapter 8 for instructions on viewing the current firmware revision.
The following information will be included in the display.
— Firmware Release = FieldFox application firmware revision
— FPGA Rev = code revision for FPGA
— SBM Boot Rev = revision of boot code for System Microcontroller
— SBM Main Rev = revision of main code for System Microcontoller
A firmware upgrade includes three sections:
— the FieldFox application firmware and the Windows CE operation system on
the A6 SOM board.
— the firmware in the System Monitor Microcontroller on the A5 system board.
— the FPGA code on the A5 system board.
The System Monitor firmware update and the FPGA code update are executed
only if not up-to-date.
It is important to maintain power to the analyzer during the update process.
After unplugging the USB flash memory stick during the firmware upgrade
process, wait for the analyzer to activate the CAT mode before operating the
analyzer.
