I’m working on an MCU by using the IAR IDE. I’m trying to analyze a hard fault:

Hard Fault

   R0 : 00032581   R1 : fffffff1
   R2 : 00000000   R3 : 2003f800
   R4 : 00000000   R5 : 2003efd8
   R6 : 00000000   R7 : 2003f800
   R8 : 00000000   R9 : 000009c6
   R10: 0000023c   R11: 00450f13
   R12: 00000002   R13: 200003c8
   R14: 00032581   R15: 00200000

                  000251da 6900001e 
2003f800 00025433 00000000 20001668

20056e08 000132f8 2001a3ec 0004a043 
00000000 00000000 00000000 0000002a 
000132f8 2001a3ec 00000000 ffffffed 
e000ef34 c0000004 0000000f 200586a4 
00000000 00024737 0002463c 49000000 
00000000 00023d93 00000000 2002e4c8 
20058804 00028cbd 00000000 00002897 
fffffff0 ffffffff ffffffff ffffffff 
ffffffff ffffffff ffffffff 00000000 
00000000 00003a63 00000000 ffffffff

I searched the generated memory map and found the R14 is associated with a function. How can I figure out the cause of the hard fault and fix it?
