The Following Menu is Displayed
All Tests
This option is used to run all tests in the menu.
Test Flash memory banks
This test programs one image location in each bank and reads them back. This is done to check the
functionality of all Image_select and Bank_select signals. The failure in any bank is indicated by the
error message “FAILED”. Else the message “OK” is displayed.
Detect Flash Assembly
This will check the presence of the Flash assy attachment and display the message “Flash assy card
detected” or “Flash assy card not detected”
Update archive status from flash assy
This option has been provided to facilitate the interchange of Flash assy cards between CPU boards.
The CPU soft ware stores and keeps updating status information on all available flash image slots.
This status info is stored in the NVRAM. When a flash assy is inserted, the status info is stored in the
NVRAM will not indicate the true status anymore. When we run this option, the CPU will check the Flash
assy and update its status stored in NVRAM.
NOTE:
This option must be run during the following instance without fail
A.) Whenever the CPU board or the Flash assy gets replaced in the field
B.) When the NVRAM gets replaced during a debugging operation.
