NuMaker-IIoT-NUC980 USER MANUAL
1 OVERVIEW
The NuMaker-IIoT-NUC980 is an evaluation board based on Arm ARM926EJ-S microprocessor
NUC980DK61Y which has rich peripherals to help users to design-in their products or application
systems easily. In addition, the NuMaker-IIoT-NUC980 uses NUC980DK61Y microprocessor which runs
up to 300 MHz with built-in 64 MB 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, SPI NAND Flash
and SD/EMMC. All functions of the NUC980DK61Y are placed on the board, including peripheral
interfaces such as memory (SPI NAND Flash, eMMC, SD), UART, Audio controller (NAU8822L), 10/100
Mbps Ethernet MAC controller, high speed USB (device, HOST), JTAG and EBI. Furthermore, the board
provides Arduino Uno compatible interface for expansion. You can use it to develop and verify
applications to emulate the real behavior.

4.3 BSP Firmware Download
NUC980 Linux BSP provides cross compilation tools based on Linux. This BSP has been tested in
different x86 Linux distributions, including Ubuntu, CentOS, and Debian, etc. Since there are many
distributions out there with different system configuration, sometimes it is necessary to change system
setting or manually install some missing components for cross compilation.
Linux development environment could either be native, or install in a virtual machine executed on top of
other operating system.
