MPC5777C Problem with NCF 42, using debugger

has someone an idea about FCCU reaction using TRACE32 ,when the NCF_42 is active?


In the MPC5777C there is the NCF 42: "Lockstep mode Indication of disabled Checker Core or RCCUs. Fault is cleared by clearing the FCCU channel status,FCCU_NCF_Sn[NCFSm]"


I'm working with FCCU active to react to NCF_42.




When i work on my ECU without TRACE32 (Lauterbach) I don't see any reset action by FCCU.


When i work with TRACE32 (Lauterbach), all is working well until I don't ask "break" on Trace32.

In this case I see the reset action driven by EOUT port of FCCU.


But if I build a new S19 using same code (but in this case keeping disabled NCF 42), all works fine with Lauterbach and also "asking" break on TRACE32.


Where I missing ?


Thanks in advance to all
