I am lost in this : Define src_ptr and dest_ptr at address 0x20001000 & 0x20002000 without assembler directives. What should I do?
Context dude, context. We have no idea what your class or assignment is asking. Please learn to formulate questions.
src_ptr EQU 0x20001000 ; ??
If you don't know how to do your homework, then you really need to talk to your teacher about that.
