My program will stop sending the serial while transmit UART .
It go to hard fault error interrupt .

What is the cause and how can I fix it?
 

Hard fault is related to external bus interface (FSMC) access, e.g. accessing not enabled memory range etc. Debugger can show you which instruction is causing the fault.
