Generating Yocto, Buildroot and Debian image

Yocto

  1. Clone the repository from the “List of supported OS” link and move your terminal to this directory.

  2. Download the layers by this command

    Code Block
    $ repo init -u https://github.com/SolidRun/meta-solidrun-arm-rzg2lc.git -b dunfell -m meta-solidrun-arm-rzg2lc.xml
$ repo sync

  3. In this stage you can modify your image configs as you want, you can find more info about it the the repository.

  4. For graphics support you need to explore in the readme file in the github and follow the instructions of this utility.

  5. Set the environment of the image that going to be build by this command

    Code Block
    $ TEMPLATECONF=$PWD/meta-solidrun-arm-rzg2lc/docs/template/conf/rzg2lc-solidrun source poky/oe-init-build-env build

  6. Build your own Yocto image by this command

    Code Block
    $ MACHINE=rzg2lc-hummingboard bitbake <target>

    • NOTE: Choose your relevant target, for example:
      -core-image-bsp: cli image.
      -core-image-weston: graphical image.
      -core-image-qt: graphical image including qt.

Buildroot/Debian

Info

Please Note:

The black rectangle represents the switch position.

Once you set the switches, you can apply the following for booting from SD card:

  1. Downloading the Debian image
    Download the image (for example Debian image ) by running the following command on your Linux/Windows PC:

    Code Block
    wget https://solid-run-images.sos-de-fra-1.exo.io/RZ/rzg2lc_build/20231122-6391518/rzg2lc-solidrun-sd-debian-6391518.img.xz

  2. Writing the image to the SD card
    Use the following commands for writing the image to an SD card:

    Code Block
    xz -dc rzg2lc-solidrun-sd-debian-6391518.img.xz | dd of=/dev/sdX bs=4k conv=fdatasync

    • For more information, please visit Flashing an SD Card .

    • Note:Plug a micro SD into your Linux PC, the following assumes that the USB-Disk / Micro-SD is added as /dev/sdX and all it’s partitions are unmounted.

    • Note: You can use the following command for writing to the SD in case you generated your own image:

      Code Block
      $ sudo dd if=/your/image/path of=/dev/sdX bs=4k conv=fdatasync

  3. SD card insertion
    Please Insert the SD card into your device.

  4. Power connection
    Connect your power adaptor to the DC jack, and then connect the adaptor to mains supply.
