 |
|
Hello,
I have a Digilent Spartan3e starter kit. One day i went out and when i
came back the lady told me that my son had dropped my kit behind my
desk. When i had a look at it, the jumpers were off of it as well. I
put them all back in their default spots according to the user guide.
the board powers up but the Done LED does not come on and i can't
perform a boundry scan without ISE hanging.
I get a message saying "There are many devices being detected. Press
yes to continue, no to stop." If i press yes, ISE/iMPACT hangs. if no,
i just get an empty iMPACT window. Someone had suggested a manual scan
but i have no idea how to do this.
Also, I emailed digilent, but i'm just a hobbyist, so i'm sure you can
imagine how that went  . I had already tried everything he suggested.
He said it might be broken. I had asked him if digilent could possibly
repair it. Still waiting on a reply.
Can someone please help? |

I'd check the jumpers against the documentation. The "default"
setting may not be what you want.
You can also check all the JTAG signals, both visually or an ohmmeter.
A scope might help too. A pin might have been kicked loose.

yeah i did try a few configurations. none of them seemed to work
though.
I use jtag via type-b usb connector on the board. i don't see anything
wrong with it. |

You can't connect JTAG directly to USB. There is probably a small
chip doing the translation.
Digilent usually publishes schematics. See if you can find the JTAG
stuff. That will let you double check the jumpers and visually check
all of those pins. There should be a daisy chain of the in/out signals
through various chips and back to the USB chip.
It's probably worth checking the power supplies since that's so easy
to do.
A careful visual inspection might find it. Do you have a good
magnifying glass?

It used to just spin forever at that point, so at least it warns you now!
Every time I've seen that message it has been due to a JTAG issue. I bet
that board has jumpers or switches to select which onboard devices are in
the chain. Make sure they're set to sane choices.

Hello,
I have a Digilent Spartan3e starter kit. One day i went out and when i
came back the lady told me that my son had dropped my kit behind my
desk. When i had a look at it, the jumpers were off of it as well. I
put them all back in their default spots according to the user guide.
the board powers up but the Done LED does not come on and i can't
perform a boundry scan without ISE hanging.
My board no longer shows "done" when I power it on, but that's because I've
somehow messed up the flash configuration and haven't got around to figuring
out what I did. However, I can still connect to the board fine, and upload
new images to the FPGA (and which point it resets and the done light comes
on). My jumper configuration is (from the top, working down):
J30: all closed
J11: all closed
JP6: closed
JP9: 3.3V
JP7: closed
All other jumpers are open. This is the default configuration, AFAIK.
If this doesn't work for you, then your board may be dead. Depending on what
equipment you have available, you might be able to debug or repair it, but
the FPGA being a BGA will make that a little tricky. Schematics (excluding
the USB to JTAG portion) are in the user guide for the board (ug230, IIRC).

We do a lot of work with BGA's here, and our standard method of
finding
BGA's that don't work due to unsoldered balls is to clamp the part
firmly
against the board and see if it works while clamped. You can try this
by hand or use a tool that looks like an overgrown vise-grip with
clamping
pads on the end. We have such a tool and cover the pads with tape for
electrical insulation.
Of course the bad news is that if this works for you, it means your
BGA has popped loose and unless you want to run it with the clamp
on, you'll need major repairs.
Cheers,
Gabor |

!!!!!!!!!!!!!!!
i was about to reply to everyone just to say that i've tried every
step mentioned when after re-reading most of the thread and getting to
Michael Brown's reply, I see that jumper 7 is open!!. looking at the
board and schems and pictures for days, i didn't notice this!!. fired
up ISE and it worked!!. I guess pictures aren't enough sometimes. you
need a list!!
thanks everybody and thanks to you Michael!! |
