We use Code-warrior 10.6.4 to build and debug the S912ZVCA family in evaluation board. We are able to build the code successfully, but can't debug using USB debugging. The program counter seems to be in 0xFFFFFF. PC starting address is 0xfd002e after reset and the PC goes to 0xFFFFFF after the function DoZeroOut(); in startup.c
Also when we use the build size around 56K, it is possible to debug and run.
