NuWriter command tool for NUC970 family processors

The Nu-writer Command Tool is a linux console application consisting of functions to access storage(eg. DRAM,NAND,SPI,eMMC) in a NUC970 family processors

NuWriter command tool Installation Steps

ubuntu :

sudo apt-get install libusb-1.0-dev

debian :

sudo apt-get install libusb-1.0-0-dev

compiler :

./configure --prefix=$PWD/install
make
make install

udev rule :

sudo install -Dm644 99-nuvoton_isp.rules /etc/udev/rules.d/99-nuvoton_isp.rules

then restart udev or reboot the system.

Download & run u-boot via SDRAM (without SD/SPI/NAND boot media):

sudo ./nuwriter -m sdram -d NUC976DK62Y.ini -a 0xE00000 -w $IMAGE_PATH/u-boot.bin -n

NAND mode examples

Burn u-boot-spl.bin to NAND:

./nuwriter -m nand -d NUC972DF62Y.ini -t uboot -a 0x200 -w $IMAGE_PATH/nand_uboot_spl.bin -v

Burn u-boot.bin to NAND:

./nuwriter -m nand -d NUC972DF62Y.ini -t data -a 0x100000 -w $IMAGE_PATH/nand_uboot.bin -v

Burn env.txt to NAND:

./nuwriter -m nand -d NUC972DF62Y.ini -t env -a 0x80000 -w $IMAGE_PATH/nand_env.txt -v

Burn linux to NAND:

./nuwriter -m nand -d NUC972DF62Y.ini -t data -a 0x200000 -w $IMAGE_PATH/970uimage -v

Burn Pack image to NAND:

./nuwriter -m nand -d NUC972DF62Y.ini -t pack -w $IMAGE_PATH/nand_pack.bin

Erase NAND (chip erase):

./nuwriter -m nand -d NUC972DF62Y.ini -e 0xffffffff

Erase NAND 10th block to 30th block:

./nuwriter -m nand -d NUC972DF62Y.ini -a 10 -e 20

Read NAND 10th block to 30th block:

./nuwriter -m nand -d NUC972DF62Y.ini -a 10 -e 1 -r $IMAGE_PATH/test.bin

SPI mode examples

Burn u-boot.bin to SPI:

./nuwriter -m spi -d NUC972DF62Y.ini -t uboot -a 0xE00000 -w $IMAGE_PATH/spi_uboot.bin -v

Burn env.txt to SPI:

./nuwriter -m spi -d NUC972DF62Y.ini -t env -a 0x80000 -w $IMAGE_PATH/spi_env.txt -v

Burn linux to SPI:

./nuwriter -m spi -d NUC972DF62Y.ini -t data -a 0x200000 -w $IMAGE_PATH/970uimage -v

Burn Pack image to SPI:

./nuwriter -m spi -d NUC972DF62Y.ini -t pack -w $IMAGE_PATH/spi_pack.bin

Erase SPI (chip erase):

./nuwriter -m spi -d NUC972DF62Y.ini -e 0xffffffff

Erase SPI 10th block to 30th block:

./nuwriter -m spi -d NUC972DF62Y.ini -a 10 -e 20

Read SPI 10th block to 30th block:

./nuwriter -m spi -d NUC972DF62Y.ini -a 10 -e 20 -r $IMAGE_PATH/test.bin

eMMC mode examples

Burn u-boot.bin to eMMC:

./nuwriter -m emmc -d NUC972DF62Y.ini -t uboot -a 0xE00000 -w $IMAGE_PATH/emmc_uboot.bin -v

Burn env.txt to eMMC:

./nuwriter -m emmc -d NUC972DF62Y.ini -t env -a 0x80000 -w $IMAGE_PATH/emmc_env.txt -v

Burn linux to eMMC:

./nuwriter -m emmc -d NUC972DF62Y.ini -t data -a 0x200000 -w $IMAGE_PATH/970uimage -v

Burn Pack image to eMMC

./nuwriter -m emmc -d NUC972DF62Y.ini -t pack -w $IMAGE_PATH/emmc_pack.bin
