Cubieboard A20 - Instalando o Kankin na NAND

Particione a NAND

w3m 'http://dl.cubieforums.com/loz/boot_partition/bootloader/cubie_nand_uboot_partition_image.bin'

dd bs=4096 if=./cubie_nand_uboot_partition_image.bin of=/dev/nand

Ou

Compile as ferramentas necessárias para particionar a NAND:

cd /opt

git clone git://github.com/linux-sunxi/sunxi-tools

cd sunxi-tools ; make

Particione o NAND (responda Y para a pergunta):

./nand-part -f a20 /dev/nand 32768 'bootloader 120480' 'boot 512' 'rootfs 0'

reinicie o cubieboard2:

shutdown -r now

Formate as partições:

mkfs.vfat /dev/nanda

mkfs.ext4 /dev/nandc

ou

mkfs.btrfs -O ^extref /dev/nandc -f

Crie os diretórios e monte a partição raiz (ext4):

mkdir /mnt/nand

mount /dev/nandc /mnt/nand

Crie os diretórios e monte a partição de boot (vfat):

mkdir /mnt/nand/boot

mount /dev/nanda /mnt/nand/boot/

mkdir /mnt/nand/boot/linux

Baixe os arquivos de boot:

wget http://hackstore.com.br/downloads/kankin-cubie2/u-boot-nand-ext4.bin.gz

Extraia os arquivos de boot:

gunzip u-boot-nand-ext4.bin.gz && mv u-boot-nand-ext4.bin /mnt/nand/boot/linux/u-boot.bin

Crie o arquivo de configuração:

touch  /mnt/nand/boot/uEnv.txt

echo -e "console=tty0\nextraargs=console=ttyS0,115200 disp.screen0_output_mode=EDID:1440x900p75 root=/dev/nandc rootwait panic=10 consoleblank=0" > /mnt/nand/boot/uEnv.txt
