    Hello Chandre,

    Our bootloader doesn't have this option. The SRAM (256KB, or 512KB) is much smaller than the size of the flash (2MB, or 3MB). There may no have enough room to store the whole application code. This is why the bootloader programs the data to the flash while loading the data from the host.

    SORRY I mentioned the Question wrongly , it is not SRAM it is 8MB SDRAM available on Hercules Development Kit TMS570LS3137.

    The TMS570LS3137 Hercules Development Kit has 8MB SDRAM Can you provide code to download the entire file to the external EMIF 8MB SDRAM and than copy to the Internal FLASH at one go if there is no abort process during download and the final CRC matches after complete download to the EMIF 8MB SDRAM

    Hello Chandre,

    Yes, you can download the whole application image into SDRAM, them program them onto the flash. It is very straightforward. I don't have a plan to write this kind of example. I am sorry for that.
