AS can download nios to epcs ？

Hi ：

I have a question ，Whether can AS model download nios project to EPCS? not .elf + .sof.

I see use the onchip_mem.hex can do it .

but I loss ,

my step :

1, creat SOPC and set "RESET VECTOR " and "EXCEPTION VECTOR" onchip memory2_0,creat sopc sucessful

2，creat nios and add C build all sucessful。

3，compiled design the FPGA project，

4，download the .pof to EPCS16(OVER)

there is only the logic in the EPCS16. the nios is loss.

IF creat a ROM with .hex. I don't know how can i do?

English is not my Mother tongue , I can't explain clearly

thank you!!

    AS当然可以下载Nios II程序。

    试一下：

    1. 使用onchipmem分别例化一个ram和一个rom，大小自己酌情设定。

    2. reset vector映射到onchip_rom，exception vector映射到onchip_ram。

    3. 重现编译sopc builder，qurtus ii。

    4. 下载配置文件sof。

    5. 重现建立软件工厂，或regenerate bsp，目的就是让nios 软件工程重新映射到新的sopc系统。

    6. 使用flash programmer下载nios程序。

    祝你好运。

    AS mode can definitely be used to download nios program into epcs.

    Try as follows:

    1. use onchip memory to instantiate ram and rom separately, set the sizes case by case.

    2. map the reset vector to onchip_rom, and the exception map to onchip_ram.

    3. recompile your sopc system, and quartus project.

    4. download the configuration file(sof).

    5. recreate a software project or regenerate bsp file, the aim is to remap the hardware environment into the new sopc system.

    6. use flash programmer to download nios program(elf).

    Best regards!

    在这里能看见中文很亲切，

    我想可能是我表达错了，我的想法是只使用AS，不使用Flash program ，因为在生成SOPC的时候，产生一个RAM/ROM的初始化文件.hex，而且我看到直接使用AS下载，把初始化文件存储到ROM或RAM里面，直接就可以下载了(我也看见有人这么下载过，但是我按照他的方法没有成功)，这样把程序交给其他人下载的时候，会方便很多

    Hi，

    I think I can'te express clearly。

    I want to only use AS module download nois and .pof ,not flash program,I find when I buld NIOS2 ,it creat a files(.hex), the files is the RAM and RAM init-files.

    so I think it can be download with ROM to EPCS ，not use FLASH program，
