2.2.1.1 Forcing Bootloader Mode

Even with a valid application, the bootloader mode can be forced by the following:

  • Option1: 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:

    • P1.1 in MSP430FR5969 (S2 button on MSP-EXP430FR5969)
    • P5.5 in MSP430FR5994 (S2 button on MSP-EXP430FR5994)
    • P2.7 in MSP430FR2433 (S2 button on MSP-EXP430FR2433)

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

  • Option2: An application calls for the 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
