  • How can I downgrade the firmware of a cyclone pro?

  • Greetings,

    We do not recommend downgrading the firmware. Is there a problem you are facing with a newer firmware?


    Takao Yamada

    • Yes, one of our product is failing on error 4003

  • Greetings,

    And this was not an issue in the past? Within the cyclone software package, look for the PROG software for your chip architecture and try to do a step-by-step flash programming session. See if you can replicate the issue using the VC command, which is where it is failing.

    Error $4003 = VC operation failed.

  • No, this was not an issue in the past.

  • Greetings,

    What did you find when using the PROG software.

  • Greetings,

    Could I get an update on this? Were you able debug this issue?
    I have updated our software recently for the cyclone Pro and cyclone max. Please use the following link to get the latest:
