Build Instructions:

    Image build
    $ MACHINE=raspberrypi4-rdk-mc source meta-cmf-raspberrypi/setup-environment
    $ bitbake rdk-generic-mediaclient-wpe-image
    Image build
    $ MACHINE=raspberrypi4-rdk-hybrid source meta-cmf-raspberrypi/setup-environment
    $ bitbake rdk-generic-hybrid-wpe-image

    The generated image resides under the directory build-<MACHINE>/tmp/deploy/images/<MACHINE> of the Yocto workspace

    Flash Procedure

    The micro SD card should not have any partition while flashing the image. The complete memory of the card should be free

    Flashing procedure
    # of - output file (the device file for the inserted micro SD card
    
    $ bzcat <IMAGE_NAME>-<MACHINE>.wic.bz2 | sudo dd of=/dev/sdb bs=4M iflag=fullblock oflag=direct conv=fsync

    1. Hi, Sri Swati Varahagiri 

      When my pi4 is connected to display only the terminal comes up. No RDK UI.

      Is it disabled on Pi4. residentapp.service status is loaded active exited. Controller Page also doesnt populate. just blank.

      I tried rdk-next nosrc, 2021q4-dunfell... This issue is there accross.

      1. Hi Akshay J ,

        Can you try to disable the getty service, terminal will not be displayed. 

        After that if the residentUI is not seen in display, check the which dri card is picked (/dev/dri/cardX), in wpeframework logs.

        Then follow the below procedure as a work around.

        1. Open wpeframework environment file. (vi /etc/wpeframework/WPEFramework.env)
        2. Add WESTEROS_DRM_CARD=/dev/dri/card0 (i.e replace existing card0 with card1 or vice versa), save and close the file.
        3. Run systemctl daemon-reload
        4. Run systemctl restart wpeframework command.
        1. Hi Sri Swati Varahagiri 

          UI isnt loading up. Curl commands are not responding. Controller UI isnt listing anything. Both wpeframework and resident app are loaded.

      Trying to get this to build, however I seem to be missing dependencies or something as I keep failing on the following task:

      1. Hi Noah,

        Your issue on wpe-webkit seems to be the common one (i.e. biggest task to compile inside the RDK) where you haven't put enough free RAM to your VirtualBox VM. Just try to put more than 8GB like 16GB which will help a lot.

      1. Hi Amar Chand 

        Can you please share the whole log?

      2. I had same problem on Ubuntu 20.04.4 LTS with gcc version 9.4.0. I had to install older version of gcc / g++. It works with gcc version 7.5.0 for me.

    4. Hi Amar Chand Can you please try what Martin Tkacik has suggested. If the the issue is not solved please try the build from Ubuntu 18.04 LTS.

    5. Using : Ubuntu => 20.0.4

      Thanks Martin Tkacik  for your reply . I tried to build the code using gcc/g++ 7.5.0 version . This time QT module build is OK  is  but now observe issue  compiling cobalt  modules . I can not attach full logs files  ,looks some permission issue.

      @ @Philip James ,  I can not use Ubuntu 18.0.4   as of now . My AWS -EC2 instance having only 20.0.4 version

      1. Hello Amar Chand . I am happy, that my suggestion is useful for you.

        Now you need to install multilib for your version of gcc/g++.

        Please try to install g++-7-multilib and gcc-7-multilib, in this case.
