NUC980 LINUX BSP INTRODUCTION
NUC980 Linux BSP provides cross compilation tools based on Linux operating system. 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.
For more detailed on how to download and install VMware virtual machine, please refer to “NUC980
Linux 3.10 BSP User Manual EN” in the “Documents”directory.

2. Insert the 5V adapter (CON1)
3. Plug in the USB cable (CON9)
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 (http://www.nuvoton.com/hq/products/microprocessors/arm9-
mpus/Software/?__locale=en&resourcePage=Y) to download the “NUC980 NON-OS BSP”. 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.

This mode can write a new image to SPI NAND flash and specify the type of the image. These types
can be recognized by uboot or Linux. The Image type is set Loader, Data, Environment or Pack.
Operation Steps
According to the figure below,follow the below steps 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. Waiting for finishing progress bar.
