    Shin,

    We currently support only ARM as the boot master on Keystone II devices in our software development kit as the chip was designed so that the ARM is the boot master. You can use DSP as the boot master as the DSP has a boot ROM and has been validated as part of the SOC tests 

    For ARM booting from NAND, you can refer to the instructions provided here:

    We also provide a secondary bootloader that wakes up the secondary cores and DSP and loads application on it in processor SDK :

    For DSP as a boot master, we do have an example for reference , that I am attaching here:

    3618.DSP_SPI_boot_example.zip

    the utilities to create the boot image and to flash are provided in the SDK, you can find them under pdk_k2hk_x_x_x_x/packages/ti/boot/. To use the flash writer, you can refer to the README or to the Keystone II Examples wiki .

    Regards,

    Rahul
