1 OVERVIEW
The NuMaker-LoRaG915/LoRaG868-NUC980 is an evaluation board for LoRa ecosystem gateway
design based on NuMicro NUC980 series microprocessor. The NuMaker-LoRaG915/LoRaG868-
NUC980 is designed for project evaluation, prototype development and function validation for LoRa
gateway application.
The NuMaker-LoRaG915/LoRaG868-NUC980 evaluation board is used for 915 MHz and 868 MHz
frequency band, respectively. Depending on the used frequency band, the NuMaker-
LoRaG915/LoRaG868-NUC980 evaluation board can be combined with the NuMaker-LoRaG-NUC980
evaluation board, as shown in Figure 1-2.
The NuMaker-LoRaG915/LoRaG868-NUC980 is based on NUC98061DKY. For the development
flexibility, the NuMaker-LoRaG915/LoRaG868-NUC980 provides the extension connectors of
NUC98061DKY, LoRa module, one RJ45 Ethernet port, one USB Host, one USB Device/Host, two sets
of RS485, and the capability of adopting multiple power supplies.
The NuMaker-LoRaG915/LoRaG868-NUC980 supports Nuvoton’s development tool “NuWriter” for
programming and virtual COM (VCOM) port for printing debug messages on PC.
In addition to Lora gateway, Nuvoton Lora ecosystem also has Lora end-devices. Please refer to
NuMaker-LoRaD-M252 User Manual for more information.
For the Lora gateway and Lora device software setup manual, please refer to Constructing LoRaWAN
Network User Manual for more information.

4 QUICK START
4.1 Preparation
The PC must install the relevant drivers to be able to communicate with the NuMaker-
LoRaG915/LoRaG868-NUC980. The following sections will introduce the installation steps and how to
run the platform.
4.2 NUC980 Linux BSP Introduction
The NUC980 Linux BSP provides cross compilation tools based on Linux operating system. The BSP
has been tested in different x86 Linux distributions, including Ubuntu, CentOS, Debian, etc. Because
there are so many distributions out there with different system configuration, it is sometimes necessary
to change system setting or manually install some missing component in order to cross compile.
Linux development environment could either be native, or install in a virtual machine executed on top of
other operating system.
For more details about NUC980 BSP, please refer to “NUC980 Linux 4.4 BSP User Manual” in the
“Documents” directory.
4.3 BSP Download
The programming tool requires a NuWriter driver to be installed on PC first. Please visit Nuvoton official
website to download the “NUC980_Linux-4.4_BSP”.
4.4 Driver Installation
The programming tool requires a Nuvoton USB driver to be installed on PC first. Please follow the
steps below to install the WinUSB driver.
Run the “WinUSB4NuVCOM.exe” before the USB cable is plugged in. The “WinUSB4NuVCOM.exe”
can be found in the “Tool” directory. Power on the NUC980 Series MPU evaluation board (EVB) and
plug the USB cable into PC, and the Windows shall find a new device and request to install the driver.

3. Plug in the USB cable and check the connection status.
If the installation in section 4.3 Driver Installation is successful, a virtual COM port named “WinUSB
driver (Nuvoton VCOM)” can be found by using “Device Manager” to check the ports devices.

4. Plug in the USB cable
The USB serial port function is used to print some messages on PC API, such as SecureCRT,
through the standard UART protocol for debugging program.
If the installation in section 4.3 Driver Installation is successful, the PC will recognize the board as
a USB composite device when the USB micro-B port connect the PC host.

Check the COM port number from device manager.
Use SecureCRT, HyperTerminal, Putty or TeraTerm to open the serial COM port, and set the baud
rate to 115200.
After pressing the reset button (SW1), the chip will reprogram application and print out debug
message.

can be recognized by uboot or Linux. The Image type is set as Loader, Data, Environment or Pack.
5.2 Operation Steps
According to Figure 5-2, follow the steps below to add image to SPI NAND Flash:
1. Select the “SPI NAND” type, which will not list the pre-burned images in the SPI NAND Flash
ROM.
2. Fill in the image information:
Image Name: Browse the image file
Image Type: Select the image type (only one type can be selected)
Image execute address: Enter image execute address. Only is Loader Type is vaild.
Image start offset: Enter image start offset.
3. Click “Program”.
4. Wait for progress bar to be finished.
5. After “Program” the image, click the “Verify” button to read back the image data to make sure
the burning status.

SPI NAND – u-boot spl
For the Linux system, Loader Type is used to boot the Linux kernel. Compile NUC980 U-Boot to get
Main U-Boot and SPL U-Boot. The SPL U-Boot is a small binary, which will move Main U-Boot into
DDR execution. The SPL U-Boot is only for NAND/SPI NAND boot. The default link address of SPL U-
Boot is 0x200. For the details of Loader Type format, please refer to “NUC980 NuWriter User Manual”
in the “Documents” directory.
