RZ/V2L EVK

The RZ/V2L EVK is the ideal board kit for RZ/V2L evaluation.

Since MIPI camera module is included, you can start evaluating RZ/V2L immediately by building an environment.

Following items are included in the RZ/V2L EVK.

Equipment	Details
RZ/V2L Evaluation Board	Evaluation board itself.
MIPI Camera Module	Google Coral Camera. Note that the CMOS sensor (OV5645) in the camera is no longer available, and should not be used for mass production. Any software support provided is for evaluation purposes only.
MicroUSB to Serial Cable	For serial communication between PC and the board.

Step 7: Deploy AI Application

This section explains how to deploy the AI Application to the RZ/V2L EVK.

Before reading this step Users are required to read Step 1~6 of Getting Started.
Getting Started Step 1~6 What kind of equipment is necessary?
Where to get RZ/V AI SDK?
How can I setup RZ/V AI SDK?
How can I build AI Applications source code?

To boot the board, bootloader and other Linux necessary files are required.
There are two types of bootloader available on RZ/V2L AI SDK.

• eSD Bootloader: The board boots up using the bootloader written on microSD card.
• eMMC Bootloader: The board boots up using the bootloader written in eMMC on the board.

Other necessary files, i.e. Linux kernel and root filesystem, are stored on microSD card.
You can use Linux PC to format the microSD card and expand the kernel and the root filesystem using SD card reader.

Preparation

Click the button This step contains both eSD and eMMC Bootloader explanation.
Please click the button below to update the explanation according to your bootloader interface.

eSD Bootloader eMMC Bootloader

For eSD eSD explanation will be shown in this style if you click "eSD Bootloader" button above.

For eMMC eMMC explanation will be shown in this style if you click "eMMC Bootloader" button above.

1. Setup RZ/V2L EVK

For eSD microSD card needs to contain bootloaders, the Linux kernel and root filesystem to boot-up the board.
You can use Linux PC to format the microSD card and expand the kernel and the root filesystem using SD card reader.

Note This step is required only when starting the AI SDK or when using the new version of AI SDK.
If you have already setup the microSD card with the latest bootloader, Linux kernel, Linux device tree file and root filesystem, skip this step and proceed to the next procedure (2. Deploy Application to the Board).

For eMMC microSD card needs to contain the Linux kernel and root filesystem to boot-up the board.
You can use Linux PC to format the microSD card and expand the kernel and the root filesystem using SD card reader.
Bootloaders must be written in eMMC on the board. You can use Windows PC to write the bootloaders on eMMC.

Note This step is required only when starting the AI SDK or when using the new version of AI SDK.
If you have already setup the microSD card and the bootloader written in eMMC on the board, skip this step and proceed to the next procedure (2. Deploy Application to the Board).

Format SD card


Create the following partitions on microSD card according to Appendix: A2. Format SD card.

For eSD

Type/Number	Size	Type of Filesystem	Contents
Primary #1	500MB (minimum 128MB)	Ext4	Linux kernel Device tree
Primary #2	All remaining	Ext4	Root filesystem

For eMMC

Type/Number	Size	Type of Filesystem	Contents
Primary #1	500MB (minimum 128MB)	FAT32	Linux kernel Device tree
Primary #2	All remaining	Ext4	Root filesystem




Write the Linux files to SD card

For eSD At first, run the below command to decompress ${WORK}/board_setup/eSD.zip.

cd ${WORK}/board_setup
unzip eSD.zip
Following three files are necessary, which must be placed on each partitions on microSD card.
They are in the ${WORK}/board_setup/eSD directory.


File	Description	microSD card partition
Image-smarc-rzv2l.bin	Linux kernel image (The boot program)	Partition 1
Image-r9a07g054l2-smarc.dtb	Linux device tree file (The configuration file for booting)	Partition 1
core-image-weston-smarc-rzv2l.tar.bz2	Linux Root filesystem	Partition 2
Follow the instruction below to prepare the microSD card.

Warning Here, we use "/dev/sdb" as microSD card device name.
1. Check if the two partitions are created successfully by running df command.
   

   df -h
   Filesystem 	Size		Used	Avail	Use %	Mounted on	
   …		…		…	…	…	…
   /dev/sdb1		…		…	…	…	…

Write the bootloaders to SD card Write the bootloaders to eMMC

For eSD Before booting up the board, you must write the latest bootloaders to microSD card.
This procedures needs to be done only once as long as you use the same version of AI SDK.

There are three files in ${WORK}/board_setup/eSD/bootloader to boot up the board.

• bl2_bp_esd-smarc-rzv2l_pmic.bin
• bl2_bp-smarc-rzv2l_pmic.srec
• fip-smarc-rzv2l_pmic.srec

Run the following commands to write these files to the microSD card to boot for eSD.

cd ${WORK}/board_setup/eSD/bootloader
sudo dd if=bl2_bp_esd-smarc-rzv2l_pmic.bin of=/dev/sdb seek=1 count=1
sudo dd if=bl2-smarc-rzv2l_pmic.bin of=/dev/sdb seek=8
sudo dd if=fip-smarc-rzv2l_pmic.bin of=/dev/sdb seek=128
sync
Warning Change /dev/sdb, to your microSD card device name.



Note If you would like to eject the microSD card, please run following command and remove the microSD card from Linux PC.

sudo eject /dev/sdb
Warning Change /dev/sdb to your microSD card device name.

For eMMC Please write the bootloaders to eMMC on the board according to Appendix: A1.Setup for eMMC Bootloader.
