    v2 board SD boots but no WiFi access

    fuzzynavel

      I’m using supplied sd card.  Image used from //avnet.me/ultra96-v2-oob link.  ultra96v2_oob_2018_3_190530.img  Followed directions from quick start card.  Minutes after boot there is no WIFi access.  No D9 LED light. Card is otherwise behaving as expected in quick start card guidance.   Thanks for any suggestions

          Sorry for the delay. I am working on that document. Also, at the time we released that May 30th image, the Access Point wasn't working yet. Therefore, you have to configure it manually to work. See the instructions below. I hope to have a new image by next week with the Access Point working.

           

          Before bringing up the WiFi interface you must first edit the /home/root/wpa_supplicant.conf file with the correct SSID and security password for your WiFi access point.  Once that is done you can run the supplied /home/root/wifi.sh script to copy the wpa_supplicant.conf file to /etc, load the kernel modules for the driver, and bring up the WiFi interface:

          #Copy the supplied wpa_supplicant.conf file to /etc

          #!!!NEED TO EDIT WITH SSID & PASSWORD FIRST!!!

          cp -f /home/root/wpa_supplicant.conf /etc

           

          # Load ATWILC3000 driver

          modprobe wilc-sdio

           

          # bring up interface

          ifconfig wlan0 up

           

          #Run wpa_supplicant for secure networking:

          wpa_supplicant -Dnl80211 -iwlan0 -c/etc/wpa_supplicant.conf -B

           

          #To add DHCP:

                      udhcpc -i wlan0

              Were you successful with these instructions? I have also included these in the Getting Started Guide posted here:

              Ultra96-V2 Development Board | Zedboard

               

              The next version will have the Ultra96-V2 acting as an Access Point, so it will be a bit simpler.
