We are using the MC9S12XEQ512.
I've had my share of ILLEGAL_BP, but this one I don't understand.
We use the following code that we lifted from the Freescale sample bootloader to do soft reset:
COPCTL = 0x01;
ARMCOP = 0x00;
When inside the debugger, a soft reset or the hard button reset causes an ILLEGAL_BP (the IP is the customary 0xff13), not always, but < 1 / 5 times. If I exit out of the debugger, the target doesn't seem to have any problem with either the soft or the hard reset.
I tried to set up a user-defined end trigger and trace, but I can never get it to work.
If somebody can shed some light, will be greatly appreciated.
