  1. Hey Digilent, Is there any update on this question? Thanking you, Sharat
  2. Dear Digilent, Thanks for taking the time to write back. I am sorry for the delay as I was sorting out other issues in my project. Fortunately, it is nearly complete! The last issue to resolve is the WIFI Adapter Issue. I tried to follow the procedure that you pointed me to, but I could not successfully build the kernel (new one in which the Ralink driver support is enabled) As mentioned earlier, I am working with the Zybo Board, so after cloning the linux-digilent folder onto my local machine (see screenshot 1) I proceeded to make the kernel by entering the command "make ARCH=arm digilent_zed_defconfig" (according to instruction) (see screenshot 2) Since i am actually working with the Zybo i decided to enter "make ARCH=arm digilent_zybo_defconfig" (see screenshot 3) But both commands return errors and i am unable to proceed further. I am primarily running Windows 10 Pro 64Bit, Vivado 2015.4 Webpack and I installed Ubuntu recently and don't have permission to run Vivado on this OS. (This means i can not install ARM GNU tools from Xilinx) Since the link that you sent me in the previous post aims to build a new kernel (zImage); I am kindly requesting you to spare me the convoluted process of setting up the toolchain and building the kernel for the zybo. Please send me the kernel (built and tested) for Zybo configured to boot linaro. (as done in the zybot tutorial) Thank you for you cooperation, Sharat
  3. Hey, is there any update on this question?
  4. Thank you @jpeyron I will wait for further instructions.
  5. Regarding: Zybot Project I am having an issue getting the USB WIFI Adapter to successfully connect to the internet. What is working: 1) Micro SD card Prepared for Boot on Zybo 2) Successfully able to boot and login to linaro 3) Connected a 4:1 USB hub to the USB port on Zybo and all ports are working - Tested this by connecting 1 mouse on all 4 ports, (one at a time) and the mouse works on all 4 ports 4) Camera is working fine, (motion is installed, server scripts copied to init.d and permissions changed) 5) Able to view Camera feed through IP Address but that address is issued through eth0 NOT wlan0 Hardware: 1) RA Link RT5370 USB Wi-Fi Adapter - linked for image - This adapter works flawlessly when I connect it to my PC. 2) Zybo, powered via 5V DC wall-wart power supply 3) Logitech C120 Webcam Note: Instead of connecting the zybo via HDMI, I have connected it to my router via Ethernet and am using SSH to send instructions In order to illustrate the problem: (lets look at the responses from terminal....) 1) When I type 'lsusb' (utility for displaying information about USB buses in the system) --> I get screenshot 1 - As you can see here, the WIFI adapter is detected fine 2) When I type 'ifconfig' --> I get screenshot 2 3) When I type 'lsmod' --> I get screenshot 3 - No kernel modules are installed 4) when I type 'sudo nano /etc/network/interfaces' --> I get screenshot 4 - which is detailing how I want the network interfaces to be set up 5) when I type 'sudo nano /etc/wpa_supplicant/wpa_supplicant.conf' --> I get screenshot 5 - Which is detailing the credentials of my network (you can see my password, it doesn't bother me) ISSUE: I am able to stream from the camera successfully through the wired internet connection (screenshot 2 shows that I have a valid IP address) The problem is getting the USB Wi-Fi Adapter to show up in 'ifconfig' so that I can use it for streaming. Doing so will allow me to detach the Zybo from the router's Ethernet connection and use it cord free on a battery pack. Please tell me how to set up RT5370 USB Wi-Fi properly on Linaro (for Zybo) and also connect to any network of choice
  6. Dear Hamster,
     
    I am really interested in your work with HDL to interface the "dirt cheap" WiFi module (ESP8266) with the Basys3 Board.
     
    I have studied your approach and its very clean and straightforward. I have some questions and I hope you have some free time to answer them.
     
     
    1) regarding file  - esp8266_driver.vhd
    I have understood how to connect to the Wi-Fi network of choice. But you have a command called "AT+CIPSTART="TCP","192.168.1.119",1125". This basically tells the modem to connect to the router on said IP address and start a TCP connection on said port number. I was not able to understand (if the ESP8266 is able to connect to the internet) what IP address it would be sending its data to? Again, basically if "192.168.1.119" is your source IP (data comes from here) then you need to specify where it needs to go right?
     
    2) If the ESP8266 module is connected (via FPGA) to a router which has a good internet connection. Can you show me on how to use it to connect to a remote server like dweet or thingspeak so I can upload some data on to that server?
     
    This would make this project a real IoT centric platform for connecting sensors to the internet using the low power, parallel computing benefits of the FPGA.
     
     
    Thanking You,

  7. Dear Jon, Thank you very much!
  8. Dear Digilent, First of all, I am running Windows 10 Pro 64Bit, Vivado 2015.4 Webpack and my hardware is the Zybo Board Rev.B.3 I am trying to instantiate the PMOD WiFi Module on one of my PMOD ports (There are 6 on this board so I chose the standard PMOD JE) but I face an error when trying to add the 'vivado-library-master' folder which I downloaded from GitHub. I followed this link in order to do that and downloaded the library zip from this link (via GitHub) Once I had the ~123Mb Zip File downloaded: 1) I extracted the zip to a folder near my projects 2) Opened up Vivado, created a new project, selected my board (already copied my board files earlier) 3) Opened up project settings > IP tab > Repository Settings >>> and tried to select the downloaded folder (folder NAME: vivado-library-master), screenshot included When I do this, click apply and close the project settings window, I am served a new window titled "critical messages" and it's screenshot is included in this post aswell Basically It tells me that two of the IP's in this folder namely PmodSD_v1_0 and PmodWIFI_v1_0 could not be included because Vivado is "unable to read IP file" **What I have already tried** 1) I have made sure that there are no spaces or special characters in the path to the folder containing the library 2) Downloaded this library zip file from GitHub multiple times to ensure that my downloaded isn't corrupt 3) Restarted my computer, created a fresh project and tried this again, this time choosing by board as the Arty FPGA Dev Board as done in a youtube video called "Pmod Monthly - November 2016 - Adding WiFi to your Digilent FPGA or Zynq Board" The problem still persists and I am stuck! Please help!
