    Hi @Megavolt91,


    Thank you for posting in Intel community forum, hope all is well and apologies for the delayed in response.

    Thanks for the details explanation, appreciate the effort on explaining the situation, it definitely helps us to understand the situation and others too.


    Just to clarify, you are able to program to Nios II configuration to EPCS controller now and Nios II is also starting up. However there is confusion in the addresses?


    Note: Nios II has been deprecated and no longer supported, hence perhaps it is advised to moved to Nios V, however we would try our best to clarify on your situation.


    Best Wishes
