About the address setting

Thank you xiwen :)

Today I tried to burn the flash with Nios II flash programmer,I specified my .sof file and the offset 0x20000,then programm.I got the message below:# !/bin/sh# # This file was automatically generated by the Nios II IDE Flash Programmer.# # It will be overwritten when the flash programmer options change.#

cd D:/Copy_of_cosmic_2009/software/simple_socket_server_6/Debug

# Creating .flash file for the FPGA configuration

Seems actually the GUI just use two commands,one is for generating a flash file,and one is for programming the flash.The problem is after I switch off and on, I tried to run my software on the board but failed, seems like I didn't really burn the flash successfully.Are there any problems about the two commands?
