error with NIOS2

--- Quote Start ---

If you are using a Windows host make sure to open the "Nios II Command Shell". You can find it in the start menu under the Nios II EDS you installed. It uses Cygwin which allows Linux oriented tools to run in Windows.

I'm using TeraAsic Board which contains Stratix IV FPGA.

Thanks . I followed the same step before also .

The steps i followed are

1)Opened Nios 2 EDS through start Menu and moved to the directory where i have .sof file .

2) Now i have to convert .sof to .flash file by using the script

" sof2flash --input= filename.sof --outpu=filename_hw.flash --offset=0x00020000 --pfl --optionbit=0x18000 --programmingmode=FPP

After this i'm able to generate .flash file successfully.

3)Now ,i programmed .sof through JTAG(Quartus ) and it is 100% successfull.

4)now i have programm flash using .flash file which i created in step 2

and i used the script

" nios2-flash-programmer --base=0x08000000 filename_hw.flash "

But the error displayed is " "there are no nios iiprocessors available which match the values specified. please check that your pld iscorrectly configured, downloading a new .sof file is necessary ".

please help me out friends .

Try running this from the Nios II Command Shell:

jtagconfig -n

Take the output and post it here in the forum, that'll tell me what JTAG devices and IP are hanging off the programming cables.

D:/a$ jtagconfig -n

1) USB-Blaster [USB-0]

024090DD EP4SGX230(.|ES)

Node 0C006E00 JTAG UART# 0

Node 19104600 Nios II# 0

This lines appeared when i type that jtagconfig command

Hmm that is strange because that 19104600 node is the Nios II JTAG debug module. That information means:

1) USB-Blaster [USB-0] <--# 1 is your cable number, you can also identify the cable using "USB-0"

024090DD EP4SGX230 <-- this is the device that was found hanging off the programing cable

Node 0C006E00 JTAG UART# 1 <-- JTAG UART with an instance ID of 0

Node 19104600 Nios II# 0 <-- Nios II JTAG debug module with an instance ID of 0

Cable 1 and Nios II JTAG debug module instance ID 0 should be the defaults when you call nios2-flash-programmer from the command line. Perhaps you can try passing in the cable number and instance IDs into nios2-flash-programmer to see if it behaves differently. If I remember correctly the flags should be -c 1 -i 0
