1 OVERVIEW
This document provides a quick start guide for the NUMAKER-RTU-NUC980 (Chili) Development
Board. Users can understand both software and hardware configurations for the NUMAKER-RTU-
NUC980 (Chili). 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 (Chili) board uses NUC980DR63YC (V2.0) or NUC980DR61YC
(V1.1/1.0) microprocessor (MPU) which runs 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 NUC980DR63YC (V2.0) or
NUC980DR61YC (V1.1/1.0) 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.

BSP Firmware Download
NUC980 Linux BSP provides cross compilation tools based on Linux. We have tested this BSP in
different x86 Linux distributions, including Ubuntu, CentOS, and Debian…etc. Because there are so
many distributions out there with different system configuration, sometimes it is 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 execute on top of
other operating system.
