Initial MultiBoot Design Considerations - Initial MultiBoot Design Considerations - UG570

Design considerations for the golden image are:

• The WBSTAR setting in the bitstream options points to the MultiBoot location.
• An IPROG command is inserted through the bitstream options to trigger loading of MultiBoot at power-up.
• The Watchdog Timer is enabled in the bitstream options.
• ICAPE3 instantiated with code to issue an IPROG command can also be included if the golden image can repair the flash and trigger another loading from the MultiBoot image.

Design considerations for the MultiBoot image are:

• The WBSTAR setting in the bitstream options points to the MultiBoot location.
• The Watchdog Timer is enabled in the bitstream options.
• ICAPE3 instantiated with code to issue an IPROG command can also be included if the MultiBoot image can upgrade the flash and trigger another loading from the upgraded MultiBoot image.
