    Question:

    How can I shorten the secure boot time in Traveo™ S6J3XXX series MCUs?

     

    Answer:

    If SHE=ON, it is possible to shorten the secure boot time by setting the following registers:

    • Platform manual: BootROM software interface
    • SHE Secure Boot Mode Marker (BDR_SBMM)

    0x0: Jump to user program before secure boot is completed

    Except 0x0(default): Jump to user program after secure boot is completed

    • Debugger Connection Wait Enable Marker (BDR_DWEM)

    0x292D3A7B: Debugger connection wait is disabled. It does not wait for debugger connection after the reset is released (included the state change from PSS mode to RUN mode).

    Except above value: Debugger connection wait enabled.
