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>
