I'm using the SD (nrf52) MBR to update our custom bootloader, in a battery powered device.We have some custom hardware which is used to disable our LDO, to enter a "Ultra Low Power" Shipping Mode, this is controlled by a GPIO. As you can imagine, turning off the LDO during a bootloader update is not ideal, is there anyway to set a GPIO pin high inside of the MBR, to keep the LDO enabled?
Thanks
