Is it of hardware issue or any library functions is missing?
can any one please help
It is required to know more details, like:
- MDK version
- Target selected
- Debug Adapter
Probably for your target there are example projects provided by MDK's Pack Installer that demonstrate matching Flash configuration settings:

If it's a 3rd-party adaptor (eg, J-Link, ST-Link), they usually come with their own utilities. Your first step should be to use those utilities to see if the adaptor on its own is working.
