◆ mcu_reboot()

void mcu_reboot ( enum reboot_state_t  reboot_state)

Reboot the MCU Should not be called during flight or ciritcal operations.

Parameters
stateThe state to reboot towards

Reboot the MCU Should not be called during flight or ciritcal operations.

  • POWEROFF will go the deep sleep
  • NORMAL will do a normal reboot (also to bootloader)
  • FAST will try to skip the bootloader
  • BOOTLOADER will try to keep the MCU in bootloader
    Parameters
    reboot_stateThe sate to reboot to
