    Rani,

    On this device, flash kernel code uses flash API to program the user application in to the flash.  Flash kernel on this device streams in the flash API and application in to the device RAM through SCI.

    Please go through the entire application report that you are reading (https://www.ti.com/lit/sprabv4). And go through the flash kernel source code available inC2000ware.  Path to kernel is mentioned in section 5.1 Implementation in sprabv4.

    Flash kernel can use SCI ROM bootloader to stream in the API and application image.  Or it can use a standalone SCI loader in RAM.  Initially, a basic kernel should be streamed in through ROM SCI bootloader - and this basic kernel can then use it's standalone SCI loader if needed.  

    Thanks and regards,
