Software Setup

Cable setup and prerequisites

Here is what you will need to power up and use the board:

  • Linux or Windows PC

  • HummingBoard Ripple with RZ/V2L SOM (HummingBoard Ripple & RZ/V2L SOM)

  • 12V Power adapter (HummingBoard Ripple has wide range input of 7V-36V, it is recommended to use 12V power adapter).

  • Micro USB to USB for console, the HummingBoard Ripple has an onboard FTDI chip.

  • IP router or IP switch

  • USB Disk and SD Card

Boot Select

Before powering up the board for the first time it is recommended to select the boot media. In order to configure the boot media, please refer to HummingBoard RZ/G2L Boot Select .

eMMC and SD connect to the same SDIO signals via MUX so we can’t have access to the SD & eMMC at the same time, select eMMC/SD by setting switch S3{6} → on : eMMC , off : SD

Generating Yocto, Buildroot and Debian image


  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

    $ repo init -u -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

    $ 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

    $ MACHINE=rzv2l-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.


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

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

  3. Build your own image by this command

Booting from SD card

The following shows how to set the switches on the boot source selector:

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

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

    • 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:

  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.

  5. Power On
    Hold on the On/Off Power button - SW1 (as shown in the figure below)

    • Note: The system should turn on by default when the power is connected (without pressing the button).

  6. Serial Connection
    Please insert the micro USB into your device, then you can refer to Serial Connection for installing necessary serial connection software in Linux/Windows.
    Once you installed the necessary serial connection software, you should be able to see the following:

  • In order to be able to log in , please insert “root” as a username as follows:


Final stages

The following stages need to be done in order to finalise the imaging:

  1. Run fdisk /dev/mmcblk0 if using SD or eMMC.

  2. Recreate the rootfs partition (mostly the second partition) by deleting it and then creating a new partition that starts at the next sector after the first one and extends to the end of the drive (or less depending on your needs).

  3. Write the new partition, when prompt about ‘Do you want to remove the signature?’ then answer with Yes.

  4. Run resize2fs /dev/mmcblk0p2 if using SD Card or eMMC.

  5. In this stage the root partition should be big enough to start populating it; but first update the RTC clock.

  6. Connect the RJ45 to your network with internet access (and DHCP server); and then run dhclient.

  7. Update the RTC clock by running ntpdate and then hwclock -w.

  8. Run apt-update commands below and then populate the root filesystem as you wish.

Here is an example of the same process in the rzg2lc device until the 3rd step (include):

After those steps you should end the process in this way (step 4 to the end):

In the end you should see with “lsblk” that the partition size is in the required size.
