Spi Nand Mode - Nuvoton NuMicro NuMaker-IIoT-NUC980G2D User Manual

NuWriter provides 7 types of images to be downloaded including DDR/SRAM, SPI, NAND, eMMC/SD,
SPI NAND, PACK and Mass Production. This chapter will guide you to download images to SPI NAND
flash. If you want to choose others types to download images. For more details about NUC980 Linux
BSP, please refer to NUC980 NuWriter User Manual in the "BSP/Documents" directory.

SPI NAND Mode

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.
The NuMaker-IIoT-NUC980G2D default firmware consists of five images:

u-boot-spl

u-boot

dtb

uImage

environment variables
Please refer to NuMaker NUC980 Linux Environment on VMware User Manual to generate these
firmware images.
u-boot-spl
For the Linux system, Loader Type is used to boot the Linux kernel. To compile NUC980 U-Boot to get
Main U-Boot and SPL U-Boot. The SPL U-Boot is a small binary file, which will move Main U-Boot into
DDR execution. The SPL U-Boot is only for NAND/SPI NAND boot. The default link address of SPL U-
Boot is 0x200. For the detailed introduction of Loader Type format, refer to NUC980 NuWriter User
Manual in the "BSP/Documents" directory
