SMARC EVK of RZ/G2L, RZ/G2LC, RZ/G2UL, RZ/V2L,
and RZ/Five
Start-up Guide
Introduction
This document provides a guide to prepare RZ/G2L, RZ/G2LC, RZ/G2UL, RZ/V2L, and RZ/Five reference boards to
boot up with the Verified Linux Package of RZ/G2L Group and the Board Support Package of RZ/V2L Group and
RZ/Five. Especially, procedures to write the bootloaders to each board are explained.
Bootloaders are written to the Flash ROM on the board using the Flash Writer tool provided by Renesas through the
minimonitor utility. This document explains the way to write these files using the Flash Writer.
After obtaining your reference board, please be sure to follow this document and write the bootloaders to the Flash
ROM before starting the evaluation.

1.4 Writing Bootloader
For the boot operation, two boot loader files need to be written to the target board. Corresponding bootloader files and
specified address information are depending on each target board as described in Table 4.
“XLS2” command of Flash Writer is used to write boot loader binary files. This command receives binary data from the
serial port and writes the data to a specified address of the Flash ROM with information where the data should be
loaded on the address of the main memory.
For example, this part describes how to write boot loader files in the case of RZ/V2L Evaluation Board Kit PMIC
version.:
>XLS2

Send the data of “bl2_bp-smarc-rzv2l_pmic.srec” from terminal software after the message “please send !” is shown.
After successfully download the binary, messages like below are shown on the terminal.

1.5 Create a microSD card to boot Linux
To boot from SD card, over 4GB capacity of blank SD card is needed. You can use Linux Host PC to expand the kernel
and the rootfs using USB card reader or other equipment.
Please format the card according to the following steps before using the card:
(1) Non-connect microSD card to Linux Host PC
$ lsblk
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) Connect microSD card to Linux Host PC with USB adapter
(3) Check the device name which is associated to the microSD card.
$ lsblk
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 /
sdb 8:16 1 29.7G 0 disk
└─sdb1 8:17 1 29.7G 0 part
sr0 11:0 1 1024M 0 rom
The message above shows the card associated with the /dev/sdb. Be careful not to use the other device names in the
following steps.
(4) Unmount automatically mounted microSD card partitions
If necessary, unmount all mounted microSD card partitions.
$ df
Filesystem 1K-blocks Used Available Use% Mounted on
udev 745652 0 745652 0% /dev
:
snip
:
/dev/sdb1 511720 4904 506816 1% /media/user/A8D3-393B

(5) Change the partition table
microSD card needs two partitions as listed in Table 5.
Table 5. Partitions of microSD card
Type/Number
Size
Filesystem
Contents
Primary #1
500MB (minimum 128MB)
FAT32
Linux kernel
Device tree
Primary #2
All remaining
Ext4
root filesystem
Set the partition table using the fdisk command like this.
$ sudo fdisk /dev/sdb
Welcome to fdisk (util-linux 2.34).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

(6) Format and mount the partitions
If the partitions were automatically mounted after the step 4, please unmount them according to the step 3.
Then format the partitions using the command below:
$ sudo mkfs.vfat -v -c -F 32 /dev/sdb1
mkfs.fat 4.1 (2017-01-24)
/dev/sdb1 has 64 heads and 32 sectors per track,
hidden sectors 0x0800;
logical sector size is 512,
using 0xf8 media descriptor, with 1024000 sectors;
drive number 0x80;
filesystem has 2 32-bit FATs and 8 sectors per cluster.
FAT size is 1000 sectors, and provides 127746 clusters.
There are 32 reserved sectors.
Volume ID is a299e6a6, no volume label.
