Memory map error in software program

Honored Contributor I



I am using Arria 10 Soc. 


My design has HPS & PIO's are connected thru Axi light weight bus to HPS.  


I instantiated a simple dut @ top level & connected to PIO's and i wrote sample c program to verify the functionality and i am getting memory mapping error. 


HW_REGS_SPAN 0x04000000 



ERROR: mmap failed 


Also followed the same steps mentioned@ 



Can anyone help me to solve this error.
