  1. Hello, I am new to FPGA programming so I am trying to do the Basys 3 Getting Started tutorial from the wiki. However, when I try to open a hardware target in Vivado, I get the error: [Labtoolstcl 44-26] No hardware targets exist on the server [TCP:localhost:3121] Check to make sure the cable targets connected to this machine are properly connected and powered up, then use the disconnect_hw_server and connect_hw_server commands to re-register the hardware targets. The cables seem to be properly connected and the board is on. I followed the commands above and get the same error. I uninstalled and installed the digilent drivers several times but I still get the error. I downloaded Adept and the Basys 3 also doesn't show up under the device manager. My computer must not be detecting it but I'm not sure why. Thanks.

    JTAG SMT2 chain limit

    Is there a limit on the number of devices the JTAG-SMT2 module can reliably have in the chain? Thanks, Dan
  3. Hi! I am currently working on a project which uses a particular version of an ARM Cortex M0. Therefore I can not use Xilinx' tools to debug the ARM core directely. Using a Nexys 3 with a Spartan 6 I am looking for other ways to debug it: In the ARM forum a user pointed out that ARM has a debugger platform called CMSIS-DAP. Does Digilent support this platform? I currently use a JTAG USB debugger from Digilent, does it support CMSIS-DAP?If not, do you know of any other possibility on how I could debug the ARM core directly and without using Xilinx tools?Any help is much appreciated!
  4. Hello, I am fairly new to linux and I am trying to program a cerebot nano. I have the JTAG-USB cable with SPI, rev. b. I have downloaded wine and the AVR programmer but I don't see the device when I enumerate in the AVR programmer. If I use djtgcfg enum, from the terminal: chris@chris-T510 ~ $ djtgcfg enum Found 2 device(s) Device: DCabUsb Product Name: DCabUsb1 V2.0 User Name: DCabUsb Serial Number: 50003C003874 I did install the usb drivers that came with the AVR programmer, using wine. Any ideas?

    Can't Program Zybo

    I'm new to FPGA work, but I think there is something wrong with the Zybo board I just received. Vivado tells me there are no debug cores. When I try to program it it says the debug core was not detected. I'm using the same project I used to program a different Zybo board, so I don't think it's the project configuration. I searched on the Vivado forum, and all I found was that this will happen if the JTAG clock frequency is less than the ILA clock frequency. I have no idea what that means. Vivado suggested I manually launch hw_server with some parameters specified. I tried that, but I still have the same issue. Can anyone here tell me how to get my board running? Or is this thing just broke?
  6. I'd like to know about moisture sensitive level (MSL) of part DIGILENT : JTAG-SMT2 , What is MSL?
  7. Hi, I'm wondering what the best approach would be to get my python code to talk to an HS1 device? My questions are: 1) What DLLs do I need to have on my target machine? 2) Should I create a PYD or can I speak to the library functions in a different way? 3) What is the latest version of the SDK ( Adpet?? ) and how are folks using it? Thanks for any pointers, Duncan
  8. We have been using the JTAG-USB for years, and need to purchase a couple more programmers. Should we be considering the JTAG-HS2 instead? It seems to do everything the JTAG-USB does, but with a faster programming rate. We typically create SVF files using iMPACT, and then use Adept on the production floor to do the programming of Xilinx XC9572XL CPLDs. The JTAG-USB works fine, but if the JTAG-HS2 will program faster, but still works essentially the same, it would be worth trying. Also, any comments regarding the upcoming JTAG-HS3 in the context of this question? Thanks in advance! Paul

    Bays3 Programming Issue

    Hi, Ever since I programmed my Basys3 board via JTAG for the first time, I noticed that the 7-segment displays would stay slightly on despite not using them in my projects. Is this type of behavior to be expected? If not, does anyone know how to overcome this issue? Thank you.
  10. Hi all, I am new to fpga so need some help in selecting a board. I need a spartan 6 board which has an flash memory and can be programmed using a JTAG. not through usb jtag. can some one help me by listing all such boards ? Thanks in advance sarath
