    Hi Oh Jong,

    Welcome to the TI E2E forum. I hope you will find many good answers here and in the TI.com documents and in the TI Wiki Pages (for processor issues).

    I looked out the document.
    there are nothing about mailbox in multi core environment on the documents.
    I programmed as follows.


    example code >


    core common :

    Mailbox_Params mbxParams;
    Mailbox_Params_init(&mbxParams);
    mbx = Mailbox_create(sizeof(MsgObj), 50, &mbxParams, NULL);


    core0:
    .
    .
    .
    if (Mailbox_pend( mbx, &msg, TIMEOUT ) == 0 )
    {
    printf("mailbox pend timeout\n");
    }
    .
    .
    .


    core 1:
    .
    .
    .
    if( Mailbox_post(mbx, &msg, TIMEOUT ));
    .
    .
    .


    are there any problems?
