This page explains how to use RZ/V2L AI Applications Demo on the RZ/V2L Evaluation Board Kit.
Supported version: RZ/V2L AI SDK v2.10
Overview
This page explains how to setup the RZ/V2L Evaluation Board Kit (EVK) using the demo binary file.
Unlike the procedure described in Getting Started, this page does not build the AI Software Development Kit (AI SDK) environment, so you can easily try running the AI Applications.
In this guide, you will be able to learn followings.
Prepare microSD card to set up operating environment
Run AI Applications on the board
The goal of this guide is to run the application and display the captured data with AI inference results on an HDMI monitor as shown below.

Preparation
This chapter describes the procedures up to the first startup of the RZ/V2L Evaluation Board Kit.
Step 1: Hardware Preparation
Refer to the guide in the link below and prepare what you need.
RZ/V2L Evaluation Board Kit Details are shown below
Other necessary equipments Details are shown below
Note 1
Unlike Demo v1.00, Windows PC is no longer required.
Note 2
Some applications support audio output in addition to the visual presentation on HDMI monitor.
If you would like to have the audio output, please prepare the HDMI monitor with speaker.
Step 2: Demo file extraction to microSD card
If you have not yet obtained the demo file, click on the link below to download it.
Note
In this section, we use a Linux PC to prepare the microSD card. If you want to use a Windows PC, we have experience with the following Windows applications to write a disk image.

sd_image/
ai_applications_demo_v2.10.dd.zip
Zip file containing the Demo microSD image.
r11an0762ej0210-rzv2l.pdf
ReadMe document describing the contents of the Demo zip file.
Run the following command to extract ai_applications_demo_v2.10.dd.zip in the sd_image folder.
cd sd_image
unzip ai_applications_demo_v2.10.dd.zip
Run the following command to check the device connected to the Linux PC before inserting the microSD card.
lsblk
Then, insert the microSD card into the Linux PC and run the same command (lsblk) again.
Confirm that the microSD device name (/dev/sdb) has been added to the terminal after inserting the card, as shown in the console window below.
Note
The microSD card device name may vary depending on the PC environment. In this manual, we use /dev/sdb as the microSD card device name.
Using the device name found above (/dev/sdb), write the disk image file into the microSD card.
After following the boot procedure in the previous section, you should be able to enter commands into the terminal screen on the HDMI monitor.
Execute the following commands. Replace <category> and <application-name> with the selected application.
cd /home/root
./<category>/<application-name>.sh
Example:
To run "Elevator passengers Counting" application, write following command.
./SmartBuilding/Elevator-passengers-Counting.sh
Note
Some applications support both MIPI/USB camera input. (Refer to List of RZ/V2L AI Applications Demo). To use USB camera for those applications, run following command.
./<category>/<application-name>.sh USB
On monitor, the application will automatically start.
Note 2
Applications with Audio Output provide the sound alert from HDMI monitor speaker in addition to the visual presentation.
E.g. Preceding Vehicle Movement Alert.
To terminate the application, press Super (Windows key) + Tab keys to switch back to terminal window and press Enter key.
If the application does not terminate, press Ctrl + C keys on the terminal window.
Step 3: Shutdown process
Follow these steps to power down the board.
Shutdown Procedures
Tips
Linux terminal has the auto-completion functionality.
Users can type "A"⇒[Tab] to get the full file/directory name that starts with "A".
$ ./A
⇒ Press [Tab] and remaining characters are completed automatically if there is only one directory/file starts from "A".
$ ./Agriculture
Users can press [Tab] for 2 times to get the path suggestion.
$ cd /home/root
