When I debug TRK-MPC5604B with codewarrior 2.10, I see below issue:
_start XXXX Bus Error - No Opcode
Error: Error in Once status register during instruction execution.
use 'gotil main' command to run until main procedure
this might be caused by debugger memory window being opened pointing to illegal/uninitialized memory when the debugger is starting. Also if variables are displayed in Variable window. If this is the case I'd suggest you to close the memory window (or set the address to 0), remove variables from Variable Window and reset the MCU or download the code again.
