Advice, please, how to view the function call tree and the contents of the MCU stack using STM32Cubeide. After the program crashes in debug the program loops in Hard_Fault_Handler () and it is not clear what cause such event.

What ability to view the contents of the call stack in CubeIDE is present?, i.e. what functions were called before the crash, preferably in the form of a tree

You can open the Fault Analyzer View (Windows > Show View > Debug ...) that gives you a little insight.

[olezhandr]

thanks, i know this method but there is no call tree or stack info

Try to change the while(1) in the Hard_Fault_Handler as follows:

static volatile int junk = 0;
while (!junk) {}
 

[olezhandr]

what is it supposed to give?

[KnarfB]

If the debugger sits in the while loop, you can set the value of junk to 1 manually and continue stepping out of the handler and back to the code that caused it.

[olezhandr]

I think this is call stack tree))

[KnarfB]

Yes, you're right.
