      Hi,

      I've been recently trying to combine SMP with Audio record. Even though I've not implemented the process to be running in 2nd core, just by adding SMP feature in SDK config stops the program from executing audio record functions. As it mentioned I kept audio record function within CPU0. As soon as I remove SMP function from SDK config, everything works fine and audio starts recording as it should be without any change in code.

      Also can you please let me know that works only in CPU0 and not in other cores.

        Hi @MatBen-0,

        I think you may have a problem because audio already uses ASMP. Subcore is used for DSP binary.

        See step 5 in https://developer.sony.com/develop/spresense/docs/sdk_tutorials_en.html#_build_flash_3

        Best Regards,
