The SoftDevice will return the application RAM start address if too little RAM has been set aside for the SoftDevice when you call sd_ble_enable() in softdevice_enable() in softdevice_handler. Specifically, it will return the app_ram_base variable, which contains the application RAM start address.

You can examine the app_ram_base variable in a debug session, see attached screenshot below.

Thanks for reply. Now working good. i want to know How to calculate the RAM ?

You need to change vs_uuid_count from 1 to 2 in softdevice_enable_get_default_config() in softdevice_handler.c, i.e.

p_ble_enable_params->common_enable_params.vs_uuid_count = 2;

You also need to modify the RAM settings under Options for Target -> Target

IRAM1 Start: 0x20001FF8

IRAM1 Size: 0x6008

Generally, whenever you're seeing that the nRF device is not advertising after you flashed you should do the following:

Start a debug session
Set a breakpoint in app_error_handler_bare in app_error.c
Run the code and if you end up in the error handler, examine the call stack and identify the function that caused the error.
Look up the error code in the SDK/SoftDevice API documentation on http://infocenter.nordicsemi.com/
