Transfer application control from core 0 to core 1 on MPC5777C

We are developing a safety critical application which we would like to run on the MPC5777C safety core (core 1 and checker running in lockstep). By default the MPC5777C starts execution on core 0. To clarify, we don't intend to develop an SMP application, rather we want to pass execution control to core 1 and suspend core 0. Also, we don't intend to purchase SMP support for our ICD since we don't intend to run core 0 and 1 simultaneously (except for a very brief moment when core 1 comes up and core 0 halts, during which time we don't need ICD support).


Is there an app note or guidelines on how to handle this startup sequence to transfer core 0 control to core 1, and to enable the checker core?


Thank you, Dan
