  1. We are currently using the Digilent JTAG HS3 cable. Our setup does not allow enough room for the module without using a right angle connector from our FPGA board which has a 2x7 pin header. On the other end we have a Motherboard with a 4 pin USB header. I'm looking for advice thoughts on a simple solution to go from a our FPGA board with the 2x7 pin header which has little vertical space (so need a right angle connection) to the Motherboard 4 pin USB header. Maybe this can't be done with a single cable? Maybe it needs to be several separate parts (i.e., right angle connector + JTAG HS3 + USB cable)? Thank you!
  2. I just received my JTAG-HS3 Rev A programming cable and if I plug it into my windows 10 machine I don't see anything unique showing up in the device manager. I know something is popping on and off because I can hear the device attached and device detached sounds from windows. So what should it show up as?
  3. Hi - I just received my HS3 adaptor, am learning FPGA on a Numato Mimas dev board. But the Mimas has a 14 pin connector on 0.1" pitch (looks like a standard ribbon connector). Checking the schematic against the HS3 docs, the pinout is the same. is an adapter available? or can you give the connector type for the HS3 so I can make one? thanks Daniel
  4. Hi, We have bought two JTAG-HS3 debuggers. One of them works perfectly, but the other one keeps returning: "1 whole scan chain (device configuration stabilizing)" or "1 whole scan chain (device configuration unstable)" when using the "targets" command. Any idea what could be the problem? Best regards Lars
  5. I'm having a problem with a brand new HS3 that has stop being recognized by impact after few days. When I received it, I used it several times to program my spartan 6 using impact. But suddently for no reason, without even having touch the board or the HS3, it stoped being recognized. So I tried the HS3 from a friend and his one is working in the same condition. For helping diagnostic, I can say that when I connect the HS3 to windows, it is recognized by the OS. Also, I can use FT_PROG to interact with the FTDI chip, read his programmation. But I can't see the HS3 with impact or even with Adept. I also noticed that the HS3 was getting hot when it was working, but now his temperature stay low. Don't know if it could help. So now I wonder what could be wrong, if someone has already had this problème and what I could do to fix my brand new HS3. Thx for your help
  6. I have a Z-Turn FPGA, based around a Xilinx Zynq 7020. Unfortunately, its JTAG port is 2x7 with 2.54mm pitch. I just realized the HS3 uses 2.00mm pitch. Is there a recommended way to convert the pin pitch? I designed my own board, but an existing option would be more convenient.
  7. I've read some previous posts mentioning that the HS3 should show up in the device manager under USB controllers as a USB to serial converter. For some reason my HS3 doesn't show up anywhere. Windows doesn't automatically detect it and install the driver for it, etc. Any suggestions for what might be preventing Windows from doing this? Update - Bad cable, after cable replacement Windows saw the HS3 and installed the driver correctly.

    How to reconfig HS3?

    I accidentally reflashed my HS3 with FTDI tool(FT_prog). Can I reconfig the EERPM? and How?

    JTAG HS3 Header

    I need to select a header to which the JTAG HS3 cable can connect. I don't see a one that is specifically made for the HS3, so I'm just looking for a header with a 2mm pitch, 14 pins total, and 2 rows. Is there any mechanical information available for the HS3? I plan to use a right-angle header, so I need to be sure that there's enough clearance for the connector.
  10. Has anybody used one of the USB over CAT5/6 extenders with a Digilent JTAG programming cable? Something like this: http://www.amazon.com/Monoprice-Extender-CAT5E-Connection-150ft/dp/B003L14ZTC/ref=pd_sim_23_1?ie=UTF8&dpID=31ZZNQ4zSSL&dpSrc=sims&preST=_AC_UL160_SR160%2C160_&refRID=09HF94P09QH47PC9MR0D We're trying to program devices that are either in different rooms or across the room from the programming computer. The main concern is that USB may not be able to supply enough power for both adapters and the JTAG device. Thanks, Will
