2.2.1.1 Force Bootloader Mode

Even with a valid application, bootloader mode can be forced by these options:

  • Option 1: An external event such as the state of a GPIO after reset.

    By default, the software checks if the following GPIOs are low after reset to force bootloader mode:

    • P1.3 in MSP430G2xxx (S2 button in MSP-EXP430G2)
    • P1.1 in MSP430F5529 (S2 button in MSP-EXP430F5529)

    This event can be modified as needed in TI_MSPBoot_AppMgr_BootisForced().

  • Option 2: An application calls execution of bootloader mode.

    The variables StatCtrl and PassWd are reserved and shared between application and bootloader. To force bootloader mode, the application sets these variables to:

    PassWd = 0xC0DE

    StatCtrl.BIT0 = 1
