Hello @QuocHuyUT ,

Thanks for your post.  You can customize the HardFault_Handler() function in the SDK's startup_mcxc144.c file.

Add some code to detect the source of the Hard Fault (please refer to Debugging Hard Faults on ARM Cortex-M | MCU on Eclipse and McuLib/src/McuHardFault.c at master · ErichStyger/McuLib · GitHub.), and then add the system reset trigger function NVIC_SystemReset().
