what are the procedures followed replacing STM32F401RE IC with same IC in NUCLEO board ? In terms of boot loader.

[Jeflet]

I am using NUCLEO-64 stm32f401 and had to replace the IC with a new one of the same type since the old one got damaged. After soldering the new IC I downloaded my l test code(LED Blinking) but the debugger stopped in HARDFAULT_HANDLER. None of my GPIOs are working. Should I should download a new boot loader or is it already built in to it. What are the procedures I should follow to make my Nucleo-Board working. Is there any material available which can help me through the procedure. Please excuse me , as I just started learning the board. Thank you in Advance.

There is nothing specific to prepare, you can easily replace the target STM32 on a given NUCLEO by the same device.

You could try to flash the original firmware to the NUCLEO-F401RE, I've attached it zipped for your convinience. In case you are using Windows: just connect the board, find the mass storage drive letter the NUCLEO creates and drag'n'drop the bin file. The NUCLEO should start blinking the LED.
