End node not hopping properly

My problem seems similar to this where in I clearly observe that end node always tries to connect to Coordinator and even if out of range doesn't talk to router node in between. Tried enabling full flash erase option etc but doesn't work. Anyone knows what is the reason?

The coordinator thinks that end node is connected to itself and hence waits for it to poll, but  end node polls the router as cordinator is out of range. Hence no data goes through.

    Does you router join the same Zigbee network? Try to use packet sniffer to serif your ZED sends beacon signal when it is out of radio coverage of ZC.

    Here is the capture. It sounds like for some reason ONLY when NV_INIT and NV_RESTORE options are enabled, below issue is observed. Basically with these options enabled for some reason after first couple of valid transactions suddenly "orphan" message comes from the ZED and coordinator re-alignment is initiated. After that everything goes for toss. Also attaching the image where I clearly explain what is happening. Let me know if you have any ideas.

    This looks like the your end device reset itself. Do you allocate memory without free them in your end device?
