    Thread Summary
    
                The user encountered issues with SPU_Init failing when using multiple SPORTs on the ADSP-21569 DVB, particularly with 2 SPORTs. The support engineer provided a demo for using multiple SPORTs simultaneously, specifically a single-transmitter multi-receiver example for the ADSP-21569. The user acknowledged the solution and will study the provided demo.

    On the 21593/21569 DVB, referring to the single SPORT Demo can run normally. 
    

    When multiple SPORTs need to be used, especially when using 2 SPORTs, SPU_Init fails. 
    

    I hope to provide a routine for using multiple SPORTs simultaneously.
