Arria 10: Remote Update may brick FPGA and Factory Fallback won't work

hi Frank,

Thanks for the hint. That actually helps to trigger the fallback to the Factory image.

However 2 questions remain:

1. Any idea why the regular CRC check is not causing a factory fallback?
2. Our application design is not actively serving the watchdog. We are using the Avalon IP "Remote Update Intel FPGA IP" Version 19.1.0. We do not set any of the Watchdog Registers in the application image, so I would have expected that the watchdog would trigger and cause a factory image fallback. But his is not happening. Instead the factory image fallback reliable works with an invalid image.

So please don't get my 2nd point wrong. This is exactly the behavior that I was asking for. But it is not what I expect from the datasheets and I would like to understand it before introducing this into production.

Thanks

best regards

Fabian
