My mcu is MC9S12X.
I have a bootloader and a app.First i write bootloader to board using TBDML and run it,then i upgrade the app through CAN by bootloader using a pc software.
If i delete the VECTOR 0 xxx in prm file of app,it's ok.
But if i undelete it,after upgrade and reboot,mcu is secured.
Why does it happen?
