Tool/software:

As shown in the figure, all areas are encrypted. When the self-written BOOT is transmitted using SCI BOOT, the code will not run.I want to know how to solve it.

    Hello,

    The SCI boot function in boot ROM will not be able to program secure memories. If you need SCI/UART boot functionality on a devicec with secure memories, you will need to create a custom SCI bootloader in flash where the flash API is allocated to secure memory.

    Thank you,

    Luke
