Devices fail to boot on weak batteries

Some units hang at power-up when the battery is low, with flash contents fine. Brown-out reset is set to its lowest level of 1.8 V and the clock is 80 MHz at 3.3 V. What is the best change?

A.Lower the flash wait states to make boot quickerB.Disable the brown-out reset to let the chip start soonerC.Increase the main stack size in the linker scriptD.Raise the brown-out level so reset holds until VDD is safe
