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

2.1.2 How to distinguish each board
The evaluation boards of RZ/G2L, RZ/G2LC, and RZ/V2L are the same Printed Circuit Board, so the differences
between each board are described as follows to distinguish. The evaluation board of RZ/G2UL is different Printed
Circuit Board compared with them.

2.1.3 How to replace the SMARC Module Board
Please be careful when replacing the board as follows.
1. Remove the four screws.
Note: The screw thread is a special shape, so be careful not to crush the screw thread.
Please recommend to prepare a torx screwdriver which is a “T6” head size.
2. Remove the screw and the board will stand up at an angle. Slide it out.
3. Insert the replacement the board diagonally, then roll the SMARC board parallel to the board and fix it with screws.

Please set the SW11 settings as follows.
•Pin no1 to no3 of the SW11 is used to control boot mode of RZ/G2L, RZ/G2LC, RZ/G2UL, and RZ/V2L.
•Pin no4 of the SW11 is used to control the input voltage from power charger to 5V or 9V. Please use a 5V
setting as initial setting.
Please select boot mode as below figures! Currently we support 2 modes in 4 modes: SCIF Download mode and QSPI
Boot mode.
Please select input voltage setting as below.
