Hi All ,

 

we have design based on MKE04Z64VLD   , the MCU  is powered by 5V and the reset PIN is connected to Supervisor 

MCP120T-460I/TT.

 

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  ?
