  1. I am starting with working design for the CMOD S7 where I program the device through SDK and all functionality works as intended. Now where I am falling short is getting the program to run out of the SPI Flash. I have been following the "How To Store Your SDK Project in SPI Flash" guide from Digilent in order to put a Microblaze design into SPI Flash on the CMOD S7 located at the link here: https://reference.digilentinc.com/learn/programmable-logic/tutorials/htsspisf/start There is a recommended offset of 0x00300000 for the CMOD A7 - My question is what is the recommended o
  2. I am interested in buying Spartan-7 FPGA Module: https://store.digilentinc.com/cmod-s7-breadboardable-spartan-7-fpga-module/ but first I would like to know if it suffers same USB cable issue as CMOD-A7: Since FTDI circuitries look similar on these two boards I just want to make sure the faulty design was not copied over from A7 onto S7.
  3. Hi, I am working on a project where i'm using Digilent zybo AP SoC with xilinx vivado for Hardware design and Xilinx SDK for software design. My application uses following protocol/peripherals: 1. UARTns16550 PL side (Programmable Logic) in interrupt mode. 2. GPIOs 3. Ethernet mac (lwIP stack) I started my software design using xilinx lwip perf client application project. Then i started modifying the perf client C code according to my need. My project contains Uartns16550, tcp/ip server and client program which receives real-time data. So coming to my problem, i am able
  4. Is it possible to write a VERILOG / VHDL code to download the programming file (fpga bitstream) to the hardware device (for example an SPI flash memory)? I'm asking this, because I would like to transfer a bit stream into a spi flash memory, which will then be mounted on an fpga card for boot and configuration. I have already written a few lines of code to write, read, and erase the contents of the 32 MB NOR flash memory (PMODSF3). I tested my code and it works without problems! However, how to read the bitstream, before writing it to the flash memory? Do I only need to transfer the
  5. Hello all, some months ago I had a Basys 2 Board that I perfectly could program via multisim, designing an schematic and then exporting the design. Now I have an Arty S7 on my hands and I would wish to do the same. I followed the tutorials: http://www.ni.com/tutorial/14871/en/ and https://reference.digilentinc.com/learn/programmable-logic/tutorials/program_fpgas_through_multisim/start An instance for the Arty S7 was created in multisim and it gave me the option to generate the VHDL file from the design (I haven't verified the file yet). Multisim won't give me the programming op
  6. Hello, I'm planning on buying the product "Cmod C2: Breadboardable CoolRunner-II CPLD Module" to make some prototypes of future designs. I saw that, in order to program its CPLD (XC2C64A), I need to buy a USB to JTAG cable. Is the Diligent's JTAG-HS1 programming cable compatible with that CPLD and board?. I will be using the last version of ISE on Windows 10, will it be a problem?. If it helps answering, this are the links of the Digilent's store of those products: Breadboardable CoolRunner-II: https://store.digilentinc.com/cmod-c2-breadboardable-coolrunner-ii-cpld-module/
  7. Hi, I'm just getting into programming FPGAs and I've made my first program "blinky light" but I cant get my computer to either find the FPGA when connected or I'm missing a step when I set up Vivado. I've ran the Synthesis, Implementation, and generated the bitstream and everything completed without any errors. I just need to know how to do last part which is to put the code on the FPGA. Thanks! What I'm using/running: Ubuntu 18.04 (OS on my computer), Vidado WebPack, Arty A7 35t, and if it helps I programmed it in Verilog
  8. Does Digilent offer any services for custom script programming to control the Analogue Discovery 2? I need to better harness the device's existing capabilities in a more streamlined manner and it would be much easier to contract this work to an expert instead going through the scripting process myself.
  9. I have a Wi-FIRE rev C board that I would like to program from the Arduino IDE. According to the ChipKIT wiki, the ChipKIT core has replaced the need for MPIDE. I hooked up the Wi-FIRE to the UART mini-USB on the top of the board (Call out 26 in the ref manual) and then tried to program from the Arduino IDE by selecting "Sketch > Upload" but I get an the following error Programmer for Microchip PIC32 microcontrollers, Version 2.1.24 No target found. Copyright: (C) 2011-2015 Serge Vakulenko An error occurred while uploading the sketch My guess is that I need to use my chi
  10. All: I've been incrementally developing both hardware (MicroBlaze with AXI peripherals) and software for the MicroBlaze itself. I've set up my software program size so that all software and hardware configuration can fit into a single .bit file. I've been able to program the flash several times, but yesterday have been getting errors while attempting to erase the flash. Notes are below. Is there a HW/SW program I could load onto the FPGA to prove or disprove that the flash is broken? Thanks!! Peter From the Vivado side: create_hw_cfgmem -hw_device [lindex [
  11. Hi there, I've just started with CPLD design, using the Digilent Coolrunner II CPLD starter board (Rev. 3.0) and successfully synthesized my code with the Xilinx ISE development software. I would now like to integrate a Cmod breadboardable CPLD module into one of my projects. I don't own a programming cable/adapter, so I was wondering if I could use the Starter Board as a programmer via its JTAG interface. Looking at the schematic, I could not find a way to connect a JTAG daisy chain with another external CPLD, because the JTAG signals are all connected in parallel. Would i
  12. Hi, I have just received a CMOS S6 evaluation board (410-282P-KIT). Before I program it with my development code I wanted to verify my setup is working Ok. I am using Xilinx 14.7 on a Windows 7 PC. I have loaded iMPACT and successfully initialised the scan chain. I assigned the demo bit file to the FPGA and the demo mcs file to the flash device. When I ask it to iMPACT to verify the contents of the flash memory it fails at address 0. The iMPACT console output is displayed below. INFO:iMPACT - Current time: 11/07/2016 13:18:16 PROGRESS_START - Starting Operation. Maximum
  13. I'm very confused as to why I can't get 3 GPIO's to work as desired. I'm trying to program 3 external shift registers. The control lines are Clk, Latch, Output Enable and Data In. I've implemented a ~240Hz timer to cycle between 4 16-bit values to be sent to the shift registers. Everything works except the 3 data inputs. The actual failure is the bit shifting and mask of each of the 16-bits of the 3 data in variables. I'm including my code and an analyzer trace (uc32 pins directly to a Saleae logic analyzer). I'd appreciate anyone that could shed some light. Thanks!
  14. When I updated the FTDI VCP drivers(http://www.ftdichip.com/Drivers/VCP.htm ,win7 X64 2.12.10), the ARTY onboard JTAG disappeared. And there are two USB-TO-COM on my computer. See attachment, please. Any suggestions? JTAG.not.work.rar
  15. Hello All, Just joined the forum, I just received my Arty board, and ported a very simple 32 bit counter design that drives LEDs (slower bits). I can synthesize and implement the design (no warnings), I can view the schematic and it looks exactly like the RTL, however, when I try to load it onto the target I get the following warning: WARNING: [Labtools 27-3123] The debug hub core was not detected at User Scan Chain 1 or 3. Resolution: 1. Make sure the clock connected to the debug hub (dbg_hub) core is a free running clock and is active OR 2. Manually launch hw_server with -e "set xsdb-user-
  16. Hello, I would like to program ARTY board with an open source programmer (like openocd or xc3sprog). Did someone managed to program the board (either load a bitstream to FPGA or write to Flash) with an open source programmer? I tried to add the IDCODE / IR-len to devlist.txt in xc3sprog and recompile but here is what I get: [email protected]:~/dev/xc3sprog$ cat devlist.txt | grep XC7A35T 0362D093 6 0x09 XC7A35T [email protected]:~/dev/xc3sprog$ ./xc3sprog -c ftdi -v -j XC3SPROG (c) 2004-2011 xc3sprog project $Rev: 774 $ OS: Linux Free software: If you contribute nothing, expect nothing!

  17. Hello, I have successfully programmed my Basys2 using the 'djtgcfg' utility under Linux dozens of times, but I'm no longer able to do so. When I attempted to program the board yesterday, I got some unusual results: > djtgcfg enum Device: 3.....O......<. Product Name: Digilent Basys2-100 User Name: 3.....O......<. Serial Number: 210155528315 > djtgcfg init -d 'Basys2' ERROR: unable to open device "Basys2" > djtgcfg init -d '3.....O......<.'

  18. Hello guys, I have a problem to configure the digital output of my Analog Discovery with a custom designed/programmed signal. I can handle the fundtions given in Waveforms and watched the tutorials. The plan is to generate a PWM with the device in C++. As compiler I am using CodeBlocks. I tried to generate a sine, which is given in the samples of waveforms, but right there I am stuck. I included the samples.h and managed, that the dwf.h is included. In Waveforms itself I only can import .txt files. Because of that I think I have to connect with the Analog Discovery with the comm
  19. Hi everybody, I have just bought a Genesys Board (Virtex 5 FPGA) and I want to use the Xilinx iMPACT Tool to program it through the dedicated USB port. Is there any documentation available about step-by-step configuration and programming of the Genesys with the iMPACT Tool, for beginners? Thank you! Holly87
