inout [15:0] SRAM_DQ,

output [19:0] SRAM_ADDR,

output SRAM_UB_N,

output SRAM_LB_N,

output SRAM_WE_N,

output SRAM_CE_N,

output SRAM_OE_N

);

main_sys u0 (

.clk_clk (CLOCK_50), // clk.clk

.reset_reset_n (KEY), // reset.reset_n

.sram_0_external_interface_DQ (SRAM_DQ), // sram_0_external_interface.DQ

.sram_0_external_interface_ADDR (SRAM_ADDR), // .ADDR

.sram_0_external_interface_LB_N (SRAM_LB_N), // .LB_N

.sram_0_external_interface_UB_N (SRAM_UB_N), // .UB_N

.sram_0_external_interface_CE_N (SRAM_CE_N), // .CE_N

.sram_0_external_interface_OE_N (SRAM_OE_N), // .OE_N

.sram_0_external_interface_WE_N (SRAM_WE_N) // .WE_N

);

endmodule

when i load software on eclipse nios 2 to board, it has notification "verify failed between address 0x200000 and 0x205517" and then have windown "Downloading ELF Process failed".
