Troubleshooting - Boot Error
If the message below appears on the screen when the boot procedure has been completed,
Warning: Boot error occurred. For details browse Error Log file.
the cause of the error can be found in the Error-Log file.
Press the Error Log softkey.
The results are displayed on the screen.
Cause of error: Data cannot be read from one or more boards.
When the instrument is booted, all the calibration data that is required must be written to the processor’s
RAM.
When the NWA application is started, the entry on the hard disk is compared with the Eprom data on the
board. If the data matches, the data is loaded from the hard disk into RAM. If there is not a match, the Eprom
data is written to the hard disk and then loaded into RAM.
If the data at the specified address cannot be read, a check is made in Config.ini to check if the board in
question should be present. If so, the board is simulated (i.e. if this board is present and is functioning
physically, the instrument will function) and an entry is made in the ErrorLog file.
If a board must always be physically present, (frequency reference, synthesizer1, NetworkControler1,
reflectometer1, reflectometer2), an error message is output.
