    Hi  ,
    

    The “Main running interrupt not detected” error in A2B usually points to a discovery or synchronization issue between the main node and its sub-nodes. Please check whether you are properly getting the SYNC signal. 

    Before discovery, please check whether the "Program During Discovery" checkbox is enabled in the ADAU1452 block of the main node.
