MPC5748G multi-core operation problem

When using Lauterbach to debug multi-core applications (first use In target reset, then run), both the z4_0 and z4_1 cores can run normally; but after removing the debugger, only z4_0 can run, while the z4_1 core cannot run normally. The code is modified by using "interrupt_control_multicore_mpc5748g" in SDK3.0RTM (CAN transceiver is added in Z4_1).
If you use Lauterbach's "Attach" function, you can see that Z4_ 1 is stuck in "IVOR1_Exception_Handler". How did this happen? I delayed 10000 times before Z4_1 initialized CAN, but it didn't work. Is the initialization timing wrong?
