问一个问题——关于NIOSII 的FLASH Programmer问题？

Programmer, NIOSII, FLASH

   先问个问题：
   如果把NIOS程序和SOPC生成的硬件逻辑一起编译成SOF文件，再写到FPGA中我测试一样可以，但是这样NIOS程序怎么执行的呢？我不是很清楚了？

  再请问：
  自己设计的板子如果要用NIOS的FLASH编程下载是不是必须要设置目标板呢？我看了一下资料这个东西不是那么简单，感觉还不怎么会，所以我没有设置目标板直接下载，NIOSII这样提示我（补充一点这个工程我在NIOSII环境下硬件仿真可以通过。）：

hello_led_0.elf
这个是我选择的FLASH编程文件
提示信息如下：

#! /bin/sh
#
# This file was automatically generated by the Nios II IDE Flash Programmer.

# It will be overwritten when the flash programmer options change.
