Can i change SP at run time in CM33?

Dear All.

I am trying to back trace and get the call of faulty application after getting an exception, in this i need to update SP from HardFault Handler.

I tried in many way like "MOV SP, Rn" , "MSR SP, Rn" and etc but finally ended up with either Compilation error or Lockup state after execution of this instruction.

Already I've updated PSP from Handler, but i need to change SP to get called stack frames.

Please help me to do this.
