Good evening of Members

I want test the de2-115 of example

(DE2_115_WEB_SERVER_RGMII_ENET0)

but , when I Ram_as , niosII 10.1 appear the message of error

----------------------------------------------------------------

Fetching file: /mnt/rozipfs/index.html.

Can't open the 404 File Not Found error page.

Have you programmed the filing system into flash?

[http_handle_receive] Error preparing response

----------------------------------------------------------------

so I reference "http://alteraforum.org/forum/showthread.php?p=115825"

and I try for renew

(New→NiosII Application and BSP from Template)

Select after of Project and Templates choose Web Server(RGMII)

Then I open Nios 10.1 Command Shell

and I enter the code:

----------------------------------------------------------------

cd d:/demo/DE2_115_Web_Server/DE2_115_WEB_SERVER_RGMII_ENET0

mkdir flash

bin2flash --location=0x100000 --input=/software/web_server_test/system/ro_zipfs.zip --output=ro.flashfs_cfi_flash1.flash

nios2-flash-programmer.exe ro.flashfs_cfi_flash1.flash --base=0x0a800000 --sidp=0x9000140 --id=0x0 --device=1 --instance=0 --program --verbose --erase-all

----------------------------------------------------------------

but , In the start enter "nios2-flash..."

It tell me , There are two or more JTAG cables available but you have not

chosen which one to use. please use the configuration dialog to pick one,

or specify a value for the --cable parameter on the command line.

I try very long time...but I can't solve the question...I don't know how do...

p.s sorry my English is very poor.
