V3S Uboot 编译

1、安装交叉编译器

wget https://releases.linaro.org/components/toolchain/binaries/latest/arm-linux-gnueabihf/gcc-linaro-6.3.1-2017.05-x86_64_arm-linux-gnueabihf.tar.xz
tar xvf gcc-linaro-6.3.1-2017.05-x86_64_arm-linux-gnueabihf.tar.xz
mv gcc-linaro-6.3.1-2017.05-x86_64_arm-linux-gnueabihf /opt/
vim /etc/bash.bashrc
# add: PATH="$PATH:/opt/gcc-linaro-6.3.1-2017.05-x86_64_arm-linux-gnueabihf/bin"
source /etc/bash.bashrc
arm-linux-gnueabihf-gcc -v
sudo apt-get install device-tree-compiler
           

2、下载编译Uboot

git clone https://github.com/Lichee-Pi/u-boot.git -b v3s-current
#or git clone https://github.com/Lichee-Pi/u-boot.git -b v3s-spi-experimental
cd u-boot
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- LicheePi_Zero_800x480LCD_defconfig
#or make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- LicheePi_Zero480x272LCD_defconfig
#or make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- LicheePi_Zero_defconfig
make ARCH=arm menuconfig

           

3、修改Uboot传参

修改 include/configs/sun8i.h

#define CONFIG_BOOTARGS        "console=ttyS0,115200 panic=5 rootwait mtdparts=spi32766.0:1M(uboot)ro,64k(dtb)ro,6M(kernel)ro,-(rootfs) root=/dev/mmcblk0p2 earlyprintk rw"

#define CONFIG_BOOTCOMMAND \
    "setenv bootm_boot_mode sec; " \
    "load mmc 0:1 0x41000000 zImage; " \
    "load mmc 0:1 0x41800000 sun8i-v3s-licheepi-zero-dock.dtb;" \
    "bootz 0x41000000 - 0x41800000; "
           

4、编译Uboot

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j8
           

5、SD卡烧入

烧入到8k偏移处。

sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/sdb bs=1024 seek=8
