You provided very little information.

You can:

Use a debugger to find the code line you code hardfaults.

Instrument your code, to do the same without running in the debugger.

Check the values of the SCB registers, to see why it hardfaulted : www.keil.com/appnotes/files/apnt209.pdf

Basically I am using HAL library.So just after HAL_Init() it is going to hard fault..Since I a very new to embedded coding can you tell What exact information you want?

I don't use HAL.

You should be able to step into the HAL_Init() function, down to the line where it faults.

If necessary, you can even switch to disassembly mode in the debugger and single-step to the faulting instruction.
