FAQ
How does a user check the state before entering hard fault when a hard fault occurs on a M0/M4 microcontroller (MCU)? Datum：2015-10-16
Since the hard fault is an exception interrupt, user can search code address from the memory address recorded by a stack pointer before entering a hardfault handler, and find the hard fault according to the address.
The steps are as follows:
- Get a starting address of the stack pointer in Debug mode;
- Enter the starting address to query stack of information in the memory;
- The stacked 7th address is the code address before entering an interrupt;
- View the content of the code address in the program window, which is the state before entering the hard fault.
