"/samples/net/coap_server" example is not working on "nrf52_pca10040" board

Hi,

As Zephyr supports nRF52xx board, I have build and flashed "/samples/net/coap_server" example for my "nrf52_pca10040" board. But, It is not working and getting Hard-Fault during "init_app". UART messages are as follows. Any one can let me know what could be issue and how to resolve it.
