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@
