I got a problem which confuses me mostly. When I update my program through CAN, if there was a failure, the MCU can't start again. the screen becomes black and can't start again, this is very bothering.  I have to dismantle the screen and use multilink to solute this problem. most severely, When OEM technicians update the program, it will become worse.  Can anyone help me to solve this problem?  The chip type is S12XEP100. thanks in advance.
