digilent jtag not detected in Vivado hw_manager

jcz · March 9, 2018

I have been using Digilent HS-2 with my development system for some months with no issues.

Recently, I needed to move the target board (a pci plug in board) to a new target system.

The new system would not accommodate the HS-2 due to physical constraints, so I got an HS-3.

The HS-3 in the new system did not work, so I moved the board back to my development system, and it did not work there either. I went back to the HS-2 and now it does not work either. In all cases the hw_server can be connected to, but says "No Target." I'm running various versions of Ubuntu, and may have done an apt update in the mean time. Thinking I may have blown out the board moving it around, I sent it back to the manufacturer for repair, but they found it to run properly in their factory, so the board seems ok.

Summary:

board is ok

Hardware Manager used to see the device using HS-2, no problems

neither HS-2 nor HS-3 works now, on either original system or new one

os: Ubuntu 16.04 LTS

Vivado 2017.4 (tried 2017.3 also, same results)

I've found various suggestions related to loading cable drivers, tried many, with no change in results, but may have screwed up udev rules, etc in the process.

Any ideas please?

Addendum: lsusb shows "Bus 001 Device 005: ID 03fd:000d Xilinx, Inc. " for the HS-3 (fwiw)

OK, let's reboot this discussion, I do not have an HS-3, I have an XUP USB-JTAG Programming Cable because I need the flex cable connection for physical compatibility with my installation. So back to square 1, I can see the FPGA in Vivado with the HS-2, but not with the XUP.

I can see the HS-2 with FTDI config, but not the XUP.

first time since purchase

Hi @jcz,

Where did you purchase the HS3 i.e. digilent website?

thank you,

Jon

jcz · March 9, 2018

Hmmmm, might have been, might have been a distributor. Sorry, I don't recall.

jpeyron · March 10, 2018

Hi @jcz,

How long have you had the JTAG HS3?

thank you,

Jon

jcz · March 10, 2018

3 weeks maybe?

HS-2 before that...

I have found a windows 10 box and am trying to use the reprogramming app, but I get the unable to load DLL "FTD2XX.dll" message. I can find that dll in the file system, but how do I get it to load?

jcz · March 12, 2018

OK, I found the dll on the FTDI website and installed it.

I rebooted my Windows 10 box.

I connected the HS-3, got messages from windows saying new device detected, new device being installed, new unknown device ready to use.

Started the Digilent FTDI configure app, this time it started without crashing.

Clicked "Find Devices" ... nothing happened.

What now???

jcz · March 12, 2018

When I try this with the HS-2 device, the app finds it

jcz · March 12, 2018

Do I have a bad HS-3? How fast can you send me another one?

jpeyron · March 9, 2018

Hi @jcz,

Looking further at your results from the lsusb the HS3 should not have an xilinx id. Did someone else use this HS3 before you? Is this the first time using it?

thank you,

Jon

Hi @jcz,

Digilent just resells the XUP USB-JTAG, so we're not able to offer a lot of advice or have the ability to change/fix the firmware for it as we did not develop the product. Xilinx support may be able to help you in this regard though.

Thanks,
JColvin

jcz · March 12, 2018

Comes from Xilinx?

jcz · March 12, 2018

OR do you hav a flex extender cable for the HS-2?

That would solve my problem...

JColvin · March 13, 2018

Hi @jcz,

Yes, Xilinx is the creator/producer of the XUP USB-JTAG. As for the flex extender cable, I'm not certain what connection your board has, but if you are using the 6-pin version of JTAG (as opposed to the 2x7 pin on the adapter), you could use a 6-pin gender changer and a 6-pin MTE cable such as the ones that I linked (with 100 mil spacing). As for the 2x7 extension cable, you could likely use something like this one.

Let me know if you have any other questions or if I entirely misunderstood what you meant by flex extender cable.

Thanks,
JColvin

jcz · March 13, 2018

The JTAG 2x7 Ribbon Cable would be just what I need, except it is male to male, and I would need male to female.

JColvin · March 13, 2018

Hi @jcz,

I would recommend using a gender changer with a 2mm pitch to go with the ribbon cable then. You're welcome to use your preferred site to get this component, but here are a couple of lists that I found that could have what you need: link and link.

Thanks,
JColvin

jcz · March 13, 2018

Ordered one from DigiKey yesterday, we'll see how it works...

jcz · March 15, 2018

Doesn't work, the gender changer swaps the two rows.

Any other ideas?

JColvin · March 15, 2018

Hi @jcz,

I'm not certain how the physical setup is on your FPGA, but the gender changer shouldn't switch signals from the cable. Is the cable oriented in the same way on both systems to make sure the signals line up? Otherwise you may need to do some individual wiring to make sure the signals all go to the correct location.

Thanks,
JColvin

jcz · March 15, 2018

If you think about it, a gender changer that is just 14 pins will inevitably switch the two rows.

I have identified a possible source for an extension (M-F) cable, hope this works out.

jcz · March 9, 2018

See above, but I'm going to reinstall it and try again.

jpeyron · March 9, 2018

Hi @jcz,

Please download Adept 2 and then use the command with both the hs2 and hs3 individually connected,

djtgcfg enum

please attach the resulting text.

thank you,

Jon
