Remote System update issue in Cyclone IV E device

We need to implement remote system update feature on cyclone IV FPGA. We are using Quartus Prime Standard Edition 18.1. We are facing issues in reconfiguring the application through NIOS S/W. ...

Hi,


Thanks for the sharing. Based on what you say means there are some differences between Cyclone IV and Cyclone V FPGA architecture where jump to application configuration from factory configuration with watchdog timer enabled in factory configuration can be done on Cyclone V but can't be done on Cyclone IV. May be you can mark it as solution for better future reference.


Thanks,

Best regards,

Sheng

Hi,

In Cyclone V there is no need to create any instructions to enable or disable the watchdog timer to switch from factory to application configuration but in cyclone IV we need to set the watchdog timer value to jump from factory to application configuration and to avoid come back to factory application after watchdog timeout happens we need to disable the watchdog timer when we set the timer value in factory configuration so once we switch to application configuration we remain there unless some error occurs.

This is for your kind information.

    Hi,

    Thanks again for your kind sharing. That was a clear clarification on how remote system update works differently between Cyclone V and Cyclone IV.
