2 First steps
This section will guide you through the initial setup of the FMLR Development Board. You only need a
Micro-USB cable to power and load pre-compiled binaries. Using more advanced tools, you can directly
develop, download and debug your own application on the development board
2.1 Jumper Configuration
In this configuration the development board is powered by its own USB connector. It will allow
programming the module using SWD or UART (USB).
•Set the jumpers properly:
•Power the development board by its own USB connector.
•Connect the mini J-Link’s programming cable to the JTA connector
2.2 Powering on the Device
The FMLR Development Board uses a standard Micro-USB connection to power and provide access to
the serial port of the MCU.
1. Plug the USB cable to Micro-USB connector.
2. Plug the other end of the Micro-USB cable to the USB port of your computer.
3. The green power LED comes up. – you are ready to go
2.3 Programming the Device
Over the USB serial connection the development board provides access to the on-chip boot loader of
the S3A678 on the FMLR module. Using tools from Renesas you can upload precompiled “ready-to-go”
firmware (intel-hex files) into the module.
To program the device using the on-chip boot-loader you need to download and install “ Renesas Flash
Programmer” Software from the Renesas website and consult the documentnation
https://www.renesas.com/us/en/doc/products/tool/doc/016/r20ut4307ej0300-rfp.pdf
1. Plug in the USB cable
2. Press and hold the Bootmode button (BM) until the end of the procedure
3. Press and release the Reset button (RES)
4. Start the “Renesas Flash Programmer” software as administrator
5. Create a new project: Choose “Renesas Synergy” as the microcontroller, enter a name and
choose the location of the project

6. Press “Connect”
7. Set the serial port name for your device
8. Click “OK”

9. You should now see a window similar to this:Choose the firmware .hex file you want to flash
10. Press “Start” to program the microcontroller
11. The flash process is finished once the message “Operation completed” appears in the
console log.
12. Release the Bootmode Button
2.4 Access Serial Port of the Device by USB (UART)
In order to view the debugging output of the FMLR Module, you need a suitable terminal application.
We recommend YAT. Connect to the device using your terminal program using the following settings:
Baud-rate 115200
Data-bits 8
Parity None
Stop-bits 1
Flow Control None
Line Ending <LF> (0x0A)
Note that the line ending character has to be set to <LF> (0x0A), else the incoming AT commands will
not get executed.
You should now be able to see the debug output of the FMLR Module.

3 Application Development and Debugging
3.1 Prerequisites
You can use the development board to develop and debug your own application. You will need the
following prerequisites to do so:
•Download and install e 2
studio
•Download and install Renesas SSP 1.7.0
•A SE ER mini J-Link
•Two micro-USB cables
•it version control
To successfully run the example LoRaWAN sensor application, you will also need a LoRaWAN gateway
connected to a LoRaWAN network server.
3.2 Getting the Sources
Clone the sources of the fmlr-61-x-rss3 project from itlab into a directory on your hard-disk. It is
accessible on https://gitlab.com/fmlr/fmlr-61-x-rss3
3.3 Copying the .pack Files
Locate the .pack files in the repository, and move them to your Renesas .pack directory.
•miromico.LoRa.1.7.0.pack
•miromico.Board_FMLR_61_U_RSS3_S3A6.1.7.0.pack
Possible target directory – yours may be different, though
•D:\Renesas\e2_studio\internal\projectgen\arm\packs
These resources are required to build the application later on
3.4 Opening the project

In e2 studio navigate to Fi e Import and select «Existing Projects into Workspace»
On the next screen click on «Browse» and navigate to the directory where you checked out your
sources. e2studio will find your project. Click «Finish» to import the project into your workspace.

3.5 Setting LoRaWAN Configuration
Once the application is loaded into the workspace, you need to set your LoRaWAN DevEUI, AppEUI
and AppKey configuration in the program. In the project tree navigate to lora_thread_entry.c and open
the file in e2 studio. You will find a struct keys. Set your network configuration within the struct.
If you use TheThingsNetwork LoRaWAN (TTN) to join your device as recommended below, you need to
acquire a unique DevEUI first. The AppEUI and the AppKey will be created in a random way by the TTN
Web Application. The DevEUI, AppEUI and AppKey need to be configured in you LoRaWAN
networkserver backend before you can configure them in the application. See chapter “Connection to a
LoRaWAN Network Server” to learn how to register a device with TTN. Please note the AppEUI is
sometimes also called JoinEUI. EUIs are 8 bytes long whereas the AppKey is 16 bytes long.
Once the EUIs and KEY are set, your application is ready to build. Select Project Bui d Project to
compile the project.
