Description
The RSU may fail to revert back to the factory image in Arria® V, Cyclone® V and Stratix® V devices due to the same reason that is documented in the following errata sheets:
One of the following invalid application configuration images may cause incorrect operation:
- A partially programmed application image
- A blank application image
- An application image assigned with a wrong start address
Resolution
To avoid this incorrect operation, use one of the following options:
- Ensure the application image is correctly stored at the right address
- Use the enable POF checking option show in Remote System Upgrade IP Core User Guide (ALTREMOTE_UPDATE) (PDF)
This feature allows the remote update block to verify the existence of an application configuration image before the image loaded.
