Hi, 

 

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. 

ALT_FPGA_BRIDGE_LWH2F_OFST=0xff200000 

HW_REGS_SPAN 0x04000000 

 

 

ERROR: mmap failed 

 

Also followed the same steps mentioned@
