Hi,
I was running fine with the codewarrior debugger on my target board having MC9S12xDP512 part till today.
But suddenly, today, on the same working board, when I try to load the debugger, it gives me "Failed to find communication speed" error.
I even tried running the unsecure command from the simulator menu which runs and at the very end, it fails saying the " The Derivative could not be unsecured".
 
So, any ideas whether my chip has gone bad or is there anything else I can still try out.
 
with regards,
Lak
