Hi All ,
we have design based on MKE04Z64VLD , the MCU is powered by 5V and the reset PIN is connected to Supervisor
on power up sometimes , the MCU enter some freeze state and can exit this state only using additional RESET or power cycle .
the MCU toggle some LED as Keep alive indication , when it's on freeze state the LED doesn't change it's state .
any idea what could cause such issue ?
