  4. Hello, We are currently using the Xilinx XC7A100T Artix-7 FPGA and we are looking for some Evaluation board to study it. XC7A100T Artix-7 FPGA Evaluation Board 410-274: https://store.digilentinc.com/nexys-4-artix-7-fpga-trainer-board-limited-time-see-nexys4-ddr/ Nexys 4 DDR Artix-7 FPGA 410-292: https://store.digilentinc.com/nexys-4-ddr-artix-7-fpga-trainer-board-recommended-for-ece-curriculum/ Just wondering do we have Schematic .DSN files or layout files available? Thanks! Sean

    GPS Pmod

    Hi @jpeyron I will test it tomorrow, here in Germany it is 9.15pm. Are you able to run my project? Btw I use the Zybo Z7

    GPS Pmod

    Hi @HelplessGuy, Are you able to run this completed Vivado 2018.2 project using the Pmod GPS, on-board SD card reader and the Zedboard? thank you, Jon

    GPS Pmod

    HI @jpeyron I am using Vivado 18.2. I am using the library of Vivado 18.2 too. In the case, that you are talking about the IP block: GPS receiver V1.1 yes. I added it over board and I took the Pmod JC.

    GPS Pmod

    Hi Hi @HelplessGuy, Looking through your posts I'm not seeing what version of vivado you are using. So... what version of vivado are you using? Are you able to download and use Vivado 2018.2? If so have you tried the verified and completed Pmod GPS project done in Vivado 2018.2 attached above? thank you, Jon

    GPS Pmod

    Hi, @xc6lx45: I tested it at home, but also not working so I went in a park. there was nothing around me. No buildings that are taller than 2 floors. and they were more than 200m away from me. I had my laptop with me and used the console of SDK (with other projects it was working perfectly.) @jpeyron: the block diagram is below. I did it as you described it above.

    Pmod wifi Interface

    Hi @Pavani Ganisetti, The errors are dealing with the constraints. Please attach a screen shot of the vivado project settings and the ip repository( where you added the vivado library). If you are able to use a different version of vivado we posted a working project of the forum thread here using Vivado 2017.4 with the Pmod WIFI and the Zedboard. thank you, Jon

    Hi @HelplessGuy, Please attach a screen shot of your Vivado block design. How big is the park? is there tall buildings close to where you were testing the project? thank you, Jon

    AD2 and WF Communication Failed error popup

    Thanks! I understand your explanation. It does sound like some FIFO control error. That would be great if you could fix this. Leaving a headless Linux system for remote logging is a lot more practical than Windows... in all other experience with USB on a small variety of Linux PC and desktops, I find Linux does a much better/faster job with USB devices, especially development systems where I am downloading new code maybe dozens of times a day or loading test code into 250 new systems. So I am really surprised that in this case, on mainstream Intel hardware on Asus motherboard, USB is worse under Linux. On this particular system I have done exactly those tasks with never a problem. I hope you can find this and get it fixed. I will be interested to hear what the problem and solution are. Sincerely...

    Tera term is displaying empty,eventhough the prior process is completed. We are using com1teraterm instead of com15 teraterm since our system supports.Is it okay to use com1 teraterm. Thank you.

    GPS Pmod

    Hi, >> cold afternoon in the park for one hour not sure if I wanted to take on GPS and FPGA at the same time... I'd probably use a laptop and Teraterm or the like to establish basic functionality via UART. Also, be aware that "cold" starting a GPS module can take a long time. It needs to download the almanac / ephemeris data. 1h seems a lot, but several minutes isn't unusual.

    Pmod SDK

    Hi @Azesinte, By the name of your project you are using the Pmod GPS. Please attach a screen shot of your vivado block design. What development board as you using? thank you, Jon

    GPS Pmod

    Hi I was creating the HW as you said, and I wrote some software in SDK (you can see it below). My only problem is, that the GPS.ping is not working. I was sitting this fu***** cold afternoon in the park for one hour but didn't get any ping. I also wrote in some other forum threats about this problem. Do you have any explaining for this? greetings! my code: /************ Include Files ************/ #include <stdio.h> #include "PmodGPS.h" #include "xil_cache.h" #include "xparameters.h" #include "xil_printf.h" /************ Macro Definitions ************/ #ifdef XPAR_CPU_CORTEXA9_0_CPU_CLK_FREQ_HZ #define PERIPHERAL_CLK 100000000 // FCLK0 frequency is not in xparameters.h for some reason #else #define PERIPHERAL_CLK XPAR_CPU_M_AXI_DP_FREQ_HZ #endif /************ Function Prototypes ************/ void DemoInitialize(); void DemoRun(); /************ Global Variables ************/ PmodGPS GPS; /************ Function Definitions ************/ int main(void) { DemoInitialize(); DemoRun(); return 0; } void DemoInitialize() { GPS_begin(&GPS, XPAR_PMODGPS_0_AXI_LITE_GPIO_BASEADDR , XPAR_PMODGPS_0_AXI_LITE_UART_BASEADDR, XPAR_CPU_CORTEXA9_0_CPU_CLK_FREQ_HZ); GPS_setUpdateRate(&GPS, 1000); } void DemoRun() { while (1) { if (GPS.ping) { GPS_formatSentence(&GPS); if (GPS_isFixed(&GPS)) { printf("Timestamp: %f\n\r", GPS_getTime(&GPS)); printf("Latitude: %s\n\r", GPS_getLatitude(&GPS)); printf("Longitude: %s\n\r", GPS_getLongitude(&GPS)); printf("Altitude: %s\n\r", GPS_getAltitudeString(&GPS)); printf("Number of Satellites: %d\n\n\r", GPS_getNumSats(&GPS)); } else { printf("Number of Satellites: %d\n\r", GPS_getNumSats(&GPS)); } GPS.ping = FALSE; } } }
  19. Hi @denizcan Such intermittent failures indicate contact issue, since you have tried several cables, it might be a broken microUSB plug or cold solder. For warranty and replacement please contact support at digilentinc dot com specifying the Date of Purchase, Seller and Purchase Order/ Web order Number.
  20. Hi @Shawn83 Under Windows' Device Manager the device should as "USB Serial Converter". In case no device shows up, like USB Serial or unknown device, please contact the support. For warranty and replacement please contact support at digilentinc dot com specifying the Date of Purchase, Seller and Purchase Order/ Web order Number. PS: The LED in AD AD2 lights up only after software connection is established.
  21. Hi @dbkincaid Try to connect manually to the device, not with auto detect.
  22. Hi @albertd200 This issue is solved in latest beta versions: https://forum.digilentinc.com/topic/8908-waveforms-beta-download/

    device-tree (spartan 6)

    We haven't come across this error before. You can look at the context around the panic in memblock.c. It could be some incompatibility, a misconfiguration of the kernel, device tree or memory ip(s) in EDK design.

    hi again, i found the error but i have no solution.. the problem is in ipserver , i can't read the ip adress IPv4 ipServer = {192,168,1,190}; in the terminal i read: Connecting to network... Connection Created Started Listening 0 Sockets listening on port: 44400 if there is no problem in "ipServer".. where is the problem whene i write in the program "deIPcK.getMyIP(ipServer);" than "xil_printf("Server started on %d.%d.%d.%d:%d\r\n",ipServer.u8[0],ipServer.u8[1],ipServer.u8[2],ipServer.u8[3], portServer);" the terminal can't write it.. thanks
