Hi All, I am using Code Warrior and a DP256, once I enable the PPL in the startup code, the True Time Sim seems to loose the connection to the target. Is there a trick to changing the Multilink clock rate so that the True Time Sim will keep working.

I always look for things that the monitor initialized (like the Stack Pointer) that the autorun program does not contain. Problem B comment: Double check the memory map for the CML12 so you know where the EEPROM is. From memory EEPROM was at $D00-$FFF on the 68HC12B32 and RAM is at...
