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>

2.1.3 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.

A termination procedure of the 50mm FPC is follows.
The top and bottom surfaces of the FPC are shown below.
1. Lift up the actuator. Use thumb or index finger.
2. Fully insert the FPC in the connector parallel to mounting surface, with the exposed conductive traces facing down
3. Rotate down the actuator until firmly closed.
Note: The PFC must be fully inserted in the connector. If not fully inserted, the actuator will not close property.
Should this be the case, lift up the actuator and repeat the process (starting with Step 1 above)
4. FPC Removal
1) Lift up the actuator.
2) Carefully remove the FPC
