Could we know the detail what's limitation why RTOS doesn't support eMMC boot? Is it OS or driver or HW issue? 3. Base on item2, if it is driver issue, will TI have plan for the driver support in the future? Thank you. Sidney",

    "content" : "Hi, From RBL perspective you can boot only from single boot media. Then the control is with SBL. You can modify SBL to achieve what you want. Assume that you have SBL in QSPI memory. Then you can load and parse a multicore App Image present in QSPI memory first (say application). Then you can initialize another memory say eMMC and load/parse App Image present on that (say Algorithm). Following this approach will need concrete effort as you need to define read/write API library for eMMC and modify SBL. I would suggest you to rather have two app images on same boot media (QSPI or NOR) and flash them at a different locations. Then you will only need to modify SBL to parse the two images.
