QUICK STARTING TO USE NK-NUC980
This chapter will help users easily to use NK-NUC980 step by step.
1. Select USB ISP mode and enable the UART_0 message
NK-NUC980 provides jumpers (SW2) to select boot-up conditions. Select USB ISP mode and
enable the UART_0 message. The statuses of SW2.1, SW2.2, SW2.6 are ON.
2. Insert the 5V adapter (CON1)
3. Plug in the USB cable (CON33)
The burning tool requires a NuWriter driver to be installed on PC first. Please follow the steps below
to install the 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 then request to
install its driver.

boot-up conditions:
1. Boot from eMMC/SD device
2. Boot from SPI FLASH device
3. Boot from NAND-type Flash ROM device
4. USB ISP mode.
The NUC980 Series MPU EVB provides jumpers to select boot-up conditions. To select USB ISP mode,
the statuses of SW2.1 and SW2.2 are ON. Other boot selects can refer to the following table:
Power-on setting

3. Enter the image execution address. Note: Execution address between 0x00000000 ~
0x01F00000 (31MB).
4. Select “Download only”or ”Download and run”.
5. Click “Download”.
Users can find the image that Nuvoton provides in the “Loader”directory. In this directory, there are two
images “u-boot-spl.bin” and “u-boot.bin”to be used. If users want to use their own application, they can
use the bin file of applicaton as Figure 4-3. Noticed that the execute address should be the same with
the setting of the application. The application setting root is as Figure 4-4 (Project→Options for
Target→Linker).
