    No HDMI on Joule 570x

    MDMardare

      Hi,

       

           I have a BenQ GL2250HM monitor and when I first booted the Joule it had HDMI output. After running the steps from https://software.intel.com/en-us/xdk/docs/config-joule-iot-dev-board the output does not work anymore. I've tried several steps from this thread No HDMI output on Joule 570x and still no luck. The only thing I haven't tried yet is to change the HDMI cable, but if it worked the first time my guess is a software/configuration problem.

       

           The BIOS ID is GTPP1D1A.X64.0143.B30.1703201838

       

           When the joule boots i see the following messages:

      [   19.286744] i915 0000:00:02.0: [drm:broxton_ddi_phy_verify_state [i915]] DDI PHY state mismatch

           Also tried with no luck:

      root@intel-corei7-64:~# export DISPLAY=:0.0

      root@intel-corei7-64:~#

      root@intel-corei7-64:~#

      root@intel-corei7-64:~# xrandr -q

      Can't open display :0.0

       

           The monitor and cable are tested on my PC and they work. Any help is appreciated.

       

      Regards,

      Madalin

          Hello Madalin,

          Thanks for reaching out!

          I noticed that you are not on the latest image, if you use the uname -a command on the latest image, you should see the message:

          Linux intel-5xx-64 4.4.41-yocto-standard #1 SMP PREEMPT Mon Mar 20 16:49:29 EET 2017 x86_64 GNU/Linux

          I suggest you to follow this guide https://software.intel.com/en-us/intel-joule-getting-started to get and install the latest Ref-OS-IoT image. Then I suggest you to follow the part of the guide found in https://software.intel.com/en-us/node/721489 in order to set up the HDMI output.

          I hope this information helps you,
          Pedro M.

            Hi Pedro,

             

            Thanks for the tips. I've installed the Ref-OS-IoT image from here: Index of /ref-os-iot/releases/1702/5xx . I've created a bootable USB and installed the image. Now uname -a shows:

            root@intel-5xx-64:~# uname -a

            Linux intel-5xx-64 4.4.41-yocto-standard #1 SMP PREEMPT Tue Feb 21 19:20:12 EET 2017 x86_64 GNU/Linux

             

            I've also tried again to use 'xrandr' and it shows something different, but still no output on the monitor:

             

            root@intel-5xx-64:~# export DISPLAY=:0.0

            Also, when I first booted the Joule, the monitor displayed even the BIOS progress. Maybe the BIOS should be different ? I'm using the one from here:  Current Release: 1D1

              I find this very strange. I simply connected my Joule to my monitor and I was able to see the output of the board as you can see in the picture above:

               

              joule.jpg

               

              Is it possible for you to test your Joule with a different monitor just to discard an issue with the monitor?

                Hello Madalin,

                Do you have any updates about this?

                  Hello Pedro,

                   

                  I've tried with several monitors and still no luck. I will try to change the HDMI cable.

                   

                  I'll update you when I try with the new cable.

                      Hello Pedro,

                       

                      I've bought 2 more hdmi to micro hdmi cables, different brands. One of them worked and the other did not. Before this I was using an hdmi-micro hdmi adapter (not cable) and maybe it broke.

                       

                      Regards,
