JTAG loader problem

[yyz1988]

Hi everyone,

I developed a board with Spartan 3E, XC3S500E

I've inserted JTAG chain to program the rom. When I lunch hex2svfsetup, I choose Spartan 3 because non Spartan 3E fpga is on list.

For

how mang jtag devices are before the PicoBlaze FPGA in your chain?

how mang jtag devices are after  the PicoBlaze FPGA in your chain?

through impact download interface I see below,

So what should I input for above two question?

I think there are 0 device before the Picoblaze FPGA and 0 device after the Picoblaze FPGA,so I input 0 and 0,but  the command windows suddenly close.why?

You only need to run 'hex2svfsetup' once and it only sets up a file so it sounds like you have done that.

You may find the 'solution' in the following thread useful...

Hi KEN

  I have carefully read the link，but I still have the problem. My board is not  Spartan-3E Starter Kit, it only have a FPGA and a flash(M25P16) and no XC2C64A CoolRunner-I or xc2s06 e.g. So there are 0 device before the FPGA and 0 device after .

Whether I shoud input 0 and 0 ? I try input 0 and 0 ,but the 'hex2svfsetup' command windows suddenly close.why?

[chapman]

Yes, you would enter '0' and '0'.  'hex2svfsetup' command only writes out a 'hex2xvf.cnf' file so do you now have one of those in your directory?

Hi KEN,

      Yes,there is a 'hex2xvf.cnf' file my directory.See below

After I finish above "hex2svfsetup.exe" and gain a 'hex2xvf.cnf' document, I begin edit  the "jtag_loader.bat ".

Because I use XILINX Platform Cable USB to download my program and my program name is "program.psm".So I write command as follows.Is it right?

if exist .\hex2svf.cnf goto one
echo Need to set up jtag chain first
hex2svfsetup.exe
echo jtag chain set up
pause
:one
hex2svf program.hex program .svf
svf2xsvf -d -i program .svf -o program .xsvf
@echo setMode -bscan > impact_batch_commands.cmd
@echo setCable -port usb21 -baud -1 >> impact_batch_commands.cmd
@echo addDevice -position 1 -file program .xsvf >> impact_batch_commands.cmd
@echo play >> impact_batch_commands.cmd
@echo quit >> impact_batch_commands.cmd
impact -batch impact_batch_commands.cmd

My program directory is G:\procedure\FPGA\EIT_2D\EIT_2D_max_20

Then I Double-click  "jtag_loader.bat ",a command windows Appear a moment as follows 

There is no change in my board,means the new "program.hex" document does not download to my board .

What should I do ?

Thank you very much.

Looking at your screen capture it appears that your computer cannot open ‘svf2xsvf’ so you need to check that it is available and can be run manually before using the batch file. Until you get past that step you are not even ready to run iMPACT. At least your original issue was never a problem at all!

Hi，KEN

  I have try open ‘svf2xsvf’ manully, the command window only appear a moment and close. I can not capture it .I change another computer to Repeat the above steps ,but it still like that. What should I do? Thank you very much.

It looks like you've got a space in some of the filenames ("program<space>.svf), and this might be confusing the tools.  Does it work if you remove those spaces?

Hi,

  Yes, there is a space in some of the filenames ("program<space>.svf) when I edit the "jtag_loader.bat ". But after I delete all of that space and save again, there is still can not run. I capture the command window when I double "svf2xsvf.exe".See below.

I does not see any error,so……Tthank you very much
