  Current RPI structure uses userland to send OpenGL commands to GPU/VPU through VCHIQ.  One of the major drawback of current approach is OpenMax IL for 64 bit is not officially supported. VCHIQ also needs changes for supporting 64 bit architecture.

       

      



Environment Setup

     

The build procedure is as follows:

  •  repo init -u https://code.rdkcentral.com/r/manifests -m rdkv-asp-nosrc.xml -b thunder-next
  •  repo sync -j4 --no-clone-bundle
  •  source meta-cmf-raspberrypi/setup-environment (select option raspberrypi-rdk-hybrid-thunder.conf)
  •  bitbake rdk-generic-hybrid-thunder-image


  • Cloning the code before login once to code.rdkcentral.com, user would get the Authentication error, even though the account is in good standing and has all the required access.
  • Please login to code.rdkcentral.com before attempting to clone.
  •  Flashing the image

       Image is flashed to SD card before inserting to RPI board.   

    Command to flash the image

        Generated image has to be flashed to an SD card using this command in local PC:

    $ sudo dd if=<path to ImageName.rpi-sdimg> of=<path to SD card space> bs=4M

Ex: 

$ sudo dd if=rdk-generic-hybrid-thunder-image_default_20200302130659.rootfs.rpi-sdimg of=/dev/sdc bs=4M

317+0 records out
1329594368 bytes (1.3 GB, 1.2 GiB) copied, 104.88 s, 12.7 MB/s
$ sync


The SD card is then inserted to the Raspberry Pi board and booted to check for containers created. The Raspberry Pi board is connected to the PC via a USB to serial converter and the logs can be checked in console or can be connected via HDMI cable to a TV and logs will be shown in the terminal
