On customer's Ecu, MPC5602D run into a special state. It seems that Mcu is hanging without functionality. In order to know what happened to Mcu, we connected Lauterbach JTAG debugger to Mcu (RESET pin is disconnected so hot plugin will not trigger unexpected reset assertion over JTAG interface) and try to "attach" to Mcu. However Lauterbach cannot access it and we can see that Lauterbach report "running (reset) " at the right- bottom of status bar. Also we cannot stop Mcu either, always show message: "access timeout, target running".
Do you know what's going on with MPC5602D? What's the status of core at that moment? What kind of issue can take MPC5602D e200z0 core into that stage?
