MC9212XEQ512 - SCI does not work after COP reset

I'm using a MC9212XEQ512 and performs a COP reset by writing to the ARMCOP register:

/* Activate watchdog */COPCTL = 0x07;/* Write wrong value to COP-timer (will cause a reset) */ARMCOP = 0xFF;


After reset, the SCI is configured. But nothing is transmitted when I try to.


But if I connect my P&E debugger, it works. I.e the SCI transmission is performed.


Can someone explain this?
