    Hi Indrajit,

    You can use CAN bootlader or UART bootloader. A bootloader is a program that runs in the microcontroller to be programmed. It receives new program information externally via some communication means and writes that information to the program memory of the MCU.

    The bootloader always runs from reset. It tries to communicate with the host. If the host responds, then it either tells the bootloader it has nothing new, or sends it new code. As the new code arrives, the old code is overwritten.

    You can find our example code for CAN bootloader, UART bootloader, Ethernet bootloader, and SPI bootloader from ti.com

    This is the link for UART bootloader:
