I have done custom bootloader, it should be jumped to application but it isn't going to jump to the application address, hard fault error is showing up?

Debug normally as you would for a Hard Fault, look at the instructions and registers at the point it faults.

​

D​etermine if data being read is correct, and addresses are correct. If doing a control transfer that there is viable Thumb code there.

​

S​tep code transitions in a debugger.

​

H​ave your HardFault_Handler output actionable data.
