Thread: Reset Teensy 4.1 to program mode

    Reset Teensy 4.1 to program mode

    Is there a magic code that will reset the Teensy 4.1 to program mode?

    I have used _reboot_Teensyduino_(); and SCB_AIRCR = 0x05FA0004; in the past, but these don't work for the Teensy 4.1.

    That should restart an ARM Teensy.

    This should put it into bootloader:
    Code:
    asm("bkpt #251"); // run bootloader

    Thanks a lot. That worked!
