Hello all, I am having a problem with my MC9S12DP256 eval board. Hopefully
somebody can help me out. I set my target in ICD-12 debugger mode. Most times I
ran my code by hitting F5 (Start/Continue), suddenly it would stop on its own.
and I saw the bottom message changed from RUNNING to ILLEGAL_BP.

There's a good chance your code went off into bogus territory and eventually encountered a 00 byte (BGND instruction). If your program has compiled-in BGND instructions, it might have hit one. Sometimes BGNDs are used to catch "can't happen" cases. A very few times, I've had this sort of thing happen when I've had a bad connection between the BDM pod and MCU.
