Arria 10: Remote Update Factory Fallback won't work & Watchdog does not trigger

Hello Farabi,

 

I understand that this is a limitation in the HW of the RSU.  However we still require a Workaround to at least be able to validate the vulnerable parts of the bitstream  before we trigger the reconfiguration from our factory load.

 

Currently we have the situation that a corrupted bitstream may brick our system, resulting in an unresponsive system which must  be sent back to service center for manual repair by flashing a new image via JTAG.

The reliable Fallback mechanism for In-System Update Capabilities was an essential point for the decision for Aria 10 devices.

Now we end up, realizing that the Fallback mechanism does not work reliable. Sorry but we require at least a possibility to check an image before executing a reconfiguration. Unless we get any information about the structure of the first 1024 & last 576 Byte of the bitstream this is not possible. Ending up with a completely unresponsive system ist not an option!

 

Thanks for any further advice. 

 

best regards

Fabian
