Step 4: Extract RZ/V AI SDK package

This step explains how to extract the RZ/V AI SDK zip file.

  1. On your Linux PC, make the working directory. 
    mkdir -p ai_sdk_work
  2. Register the working directory path to an environment variable. 
    export WORK=<path to the working directory>/ai_sdk_work
  3. Move to the working directory. 
    cd ${WORK}
  4. Extract RZ/V AI SDK zip file under the working directory. 
    unzip <Path to the file>/RTK0EF0*.zip -d ${WORK}
  5. Check the working directory to confirm the package contents. 
    ls ${WORK}/
    • If the above command prints followings, the package is extracted correctly. 
      ai_sdk_setup  board_setup  documents  references r11an0*.pdf


Step 5: Setup RZ/V AI SDK

This step explains how to setup the RZ/V AI SDK environment.

Note Make sure that you have installed Docker on your Linux PC.
RZ/V2L RZ/V2H RZ/V2N
  1. On your Linux PC, move to the working directory. 
    cd ${WORK}/ai_sdk_setup
  2. Build docker image.
    sudo docker build -t rzv2l_ai_sdk_image --build-arg PRODUCT="V2L" .
    sudo docker build -t rzv2h_ai_sdk_image --build-arg PRODUCT="V2H" .
    sudo docker build -t rzv2n_ai_sdk_image --build-arg PRODUCT="V2N" .
  3. Create new directory to be mounted on Docker container. 
    mkdir ${WORK}/ai_sdk_setup/data
  4. Create docker container.
    Here, rzv2*_ai_sdk_container is a name of docker container, which can be changed by user. 
    sudo docker run -it --name rzv2l_ai_sdk_container -v $(pwd)/data:/drp-ai_tvm/data rzv2l_ai_sdk_image
    sudo docker run -it --name rzv2h_ai_sdk_container -v $(pwd)/data:/drp-ai_tvm/data rzv2h_ai_sdk_image
    sudo docker run -it --name rzv2n_ai_sdk_container -v $(pwd)/data:/drp-ai_tvm/data rzv2n_ai_sdk_image
    The local $(pwd)/data is mounted to /drp-ai_tvm/data on the Docker container by the above command option.
    For example, you can use this directory to copy files created on the Docker container to your local environment.

    docker

  5. To exit docker, run following commands.
    exit
  6. To start the docker container again, run the following command.
    sudo docker start -i rzv2l_ai_sdk_container
    sudo docker start -i rzv2h_ai_sdk_container
    sudo docker start -i rzv2n_ai_sdk_container

    File Description
    core-image-weston-rzv2n-evk.rootfs.wic.bmap SD card image
    core-image-weston-rzv2n-evk.rootfs.wic.gz
    Follow the instruction below to prepare the microSD card.
    1. Before inserting the microSD card to your Linux PC, open the terminal on Linux PC and run the following command to check the devices without microSD card.
      lsblk
      Following is the example output.
      NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 30.9G 0 disk
├─sda1 8:1 0 512M 0 part /boot/efi
├─sda2 8:2 0 1K 0 part
└─sda5 8:5 0 30.3G 0 part /
sr0 11:0 1 1024M 0 rom

    2. Insert the microSD card to your Linux PC and run the following command again.
      lsblk

    3. Check the output and confirm the name appeared. This would be your microSD card device name.
      • Following is the example output.
        NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 30.9G 0 disk
├─sda1 8:1 0 512M 0 part /boot/efi

        • /dev/sdb: The device name for the entire microSD card.
        • /dev/sdb1: The partition name in microSD card. There may be multiple sdb* depending on the microSD card.
        Warning Be careful not to use the name of other device since it may destruct your computer filesystem.

    4. To use bmaptools, microSD card partitions must be unmounted.
      Run the following command to check the automatically mounted microSD card partitions.
      df -h
    5. Check the output and find the mount point, which is "/media/user/9016-4EF8" in the following example.
