RZ/G2L, RZ/G2LC and RZ/V2L SMARC EVK
Start-up Guide
Introduction
This document provides a guide to prepare RZ/G2L, RZ/G2LC and RZ/V2L reference boards to boot up with the
RZ/G2L and RZ/V2L Group Board Support Package. 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.

1. Preparing Flash Writer
Flash Writer is built automatically when building BSP by bitbake command. Please refer to the Release Note of the
RZ/G2L and RZ/V2L Group Board Support Package to obtain a binary file of Flash Writer.
If you need latest one, please get source code from the GitHub repository and build it according to the following
instructions. In general, new revision of reference boards requires latest Flash Writer.
1.1 Preparing cross compiler
FlashWriter runs on target boards. Please get cross compiler built by Linaro or setup a Yocto SDK.
ARM toolchain:
$ cd ~/
$ wget https://developer.arm.com/-/media/Files/downloads/gnu-a/10.2-2020.11/bi
nrel/gcc-arm-10.2-2020.11-x86_64-aarch64-none-elf.tar.xz
$ tar xvf gcc-arm-10.2-2020.11-x86_64-aarch64-none-elf.tar.xz
Yocto SDK:
Build an SDK according to Release Notes and install it to a Linux Host PC. Then, enable the SDK as below.
$ source /opt/poky/3.1.5/environment-setup-aarch64-poky-linux
1.2 Building Flash Writer
Get source codes of Flash Writer from the GitHub repository and checkout the branch rz_g2l.
$ cd ~/
$ git clone https://github.com/renesas-rz/rzg2_flash_writer.git
$ cd rzg2_flash_writer
$ git checkout rz_g2l
Build Flash Writer as an s-record file by the following commands. Please specify a target board by “BOARD”option.
ARM toolchain:
$ export PATH=$PATH:~/gcc-arm-10.2-2020.11-x86_64-aarch64-none-elf/bin
$ export CROSS_COMPILE=aarch64-none-elf-
$ export CC=${CROSS_COMPILE}gcc
$ export AS=${CROSS_COMPILE}as
$ export LD=${CROSS_COMPILE}ld
$ export AR=${CROSS_COMPILE}ar
$ export OBJDUMP=${CROSS_COMPILE}objdump
$ export OBJCOPY=${CROSS_COMPILE}objcopy
$ make clean
$ make BOARD=<board>
Yocto SDK:
$ make clean
$ make BOARD=<board>

2.4 Writing Bootloader
“XLS2” command of Flash Writer is used to write 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.
This is an example of writing “bl2_bp-smarc-rzv2l_pmic.srec” which should be loaded to 11E00h of the main memory
and 000000h of the Flash ROM.

In case booting from micro SD card on SMARC carrier board, set environment variables using the commands below.
The commands below are for the RZ/V2L board. Please replace the file names in “bootcmd” according to the Release
Note when you use other boards.
=> setenv bootargs 'root=/dev/mmcblk1p2 rootwait'
=> setenv bootcmd 'mmc dev 1;fatload mmc 1:1 0x48080000 Image-smarc-rzv2l.bin;
fatload mmc 1:1 0x48000000 r9a07g054l2-smarc.dtb; booti 0x48080000 - 0x480000
00'
=> saveenv
Saving Environment to MMC... Writing to MMC(0)….OK
Note) The setting above assumes the SD card has two partitions and stores data as below:
First partition: formatted as FAT, includes Image-smarc-rzv2l.bin and r9a07g054l2-smarc.dtb
Second partition: formatted as ext4, rootfs image is expanded
Note) "saveenv" command on u-boot sometime fails.
Workaround: Turn off/on or reset the board and retry the command again.
Now the board can bootup normally. Please turn off and on the power again to boot up the board.
