1 OVERVIEW
This document provides a quick start guide for the NuMaker RTU NUC980 Development Board. Users
can understand both software and hardware configurations for the NuMaker RTU NUC980. The
platform provides Linux OS and plenty of industrial control protocol for users to implement the
Ethernet control applications in a very short time.
The NuMaker RTU NUC980 board uses NUC980DR61YC microprocessor run up to 300 MHz with
built-in 64MB DDR2 memory, 16 KB I-cache, 16 KB D-cache and MMU, 16 KB embedded SRAM and
16.5 KB IBR (Internal Boot ROM) for system booting from USB and SPI flash, all functions of the
NUC980DR61YC are placed on the board, including peripheral interfaces such as SPI Flash memory,
UART, 10/100 Mb Ethernet MAC controller, high speed USB (Device, Host), JTAG, RS485 and CAN
transceiver controller. Users can use it to develop and verify applications to emulate the real behavior.

4 QUICK START
BSP Download
The burning tool requires a NuWriter driver to be installed on PC first. Please follow the steps below to
install the driver.
Please visit nuvoTon’s NuMicro™ website https://www.nuvoton.com/products/iot-solution/iot-
platform/numaker-server-nuc980/?group=Software&tab=2) to download the “NUC980_Linux-
4.4_BSP_v1.02.001”. 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
EVB and plug the USB cable into PC, the Windows shall find a new device and then request to install
its driver. Simply follow the installation and optional steps to install USB Driver, included VCOM driver.
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 EVB and plug the USB cable
into PC, the Windows shall find a new device and request to install the driver.
