  1. Hello, I am currently working on a project using the Zedboard and some Pmods from Digilent. As of now, I have booted Ubuntu 16.04 onto the ARM core using the Petalinux tools through an SD card. I have also been looking into the GPS pmod and got the bare-metal example to work from programming the FGPA. Through my personal computer (Ubuntu 18.04), I have been able to interface with the Ubuntu 16.04 on the ARM and the GPS pmod. However, I am a little confused as to how the GPS pmod in the PL communicates with the Ubuntu on the ARM. I would really appreciate some insight on the last leg of th
  2. Hi, I have a project that uses Arty Z7-10 with pmodgps to receive the NMEA sentences every few seconds (I am using the GPS_getSentence function directly, rather than the sample code on github). The problem I am facing is whenever I program Arty via JTAG with a USB cable, my pmodgps is working correctly, but If I program the QSPI flash memory and use FSBL to boot it up, it seems to stop working. I have other pmods that are working fine in both cases, and only gps is not working as I am expecting. This seems like a weird bug to me. Does anybody have any idea what could be wrong?
  3. Hello all, I have connected PmodGps to JA connector of zedboard. I have downloaded the pmod example code(Microblaze) and did a little modification for Zynq devices. The code is listed below. For some reasons the code does not seem to be working. (The build is finished but there is blank terminal. Its not going inside that while loop. Probably because GPS.Ping does not get any data). And there is a minor warning in one of the files of BSP (bsp -> ps7_coretexa9_0 -> libsrc -> PmodGps_v1_1 - > src - PmodGPSselftest.c). I have attached the screenshots for better understandi
  4. Hello, I am using Arty board to collect GPS data every second and prints it out to terminal. To do this, I modified PmodGPS example code on github which is attached (I wrote my code in C++, rather than the original code which was in C). I wanted to completely disable interrupts and poll data every second by myself, so I removed the interrupt part of the code, but apparently PmodGPS is not working without interrupts. Even though the GPS is getting a lock, I do not see any information printed out in terminal which means GPS.ping never goes to 1. Am I doing something wrong or the GPS is not
