一、鏡像打包
目前，我的Buildroot/Uboot/Linux的文件夾組織如下圖所示
、
我的打包腳本如下：
#! /bin/bash
rm -rf ./output
mkdir ./output
cd ./output
OUT_FILENAME="flashimg.bin"
UBOOT_FILE=../u-boot/u-boot-sunxi-with-spl.bin
KERNEL_DIR=../linux
KERNEL_MODULES_DIR=$KERNEL_DIR/out/*
DTB_FILE=$KERNEL_DIR/arch/arm/boot/dts/suniv-f1c100s-licheepi-nano.dtb
KERNEL_FILE=$KERNEL_DIR/arch/arm/boot/zImage
ROOTFS_FILE=../buildroot-2019.02.2/output/images/rootfs.tar
SPEC_FILE=./custom/*
SCRIPTES=./scripts/*.sh
dd if=/dev/zero of=$OUT_FILENAME bs=1M count=16
dd if=$UBOOT_FILE of=$OUT_FILENAME bs=1K conv=notrunc
dd if=$DTB_FILE of=$OUT_FILENAME bs=1K seek=1024 conv=notrunc
dd if=$KERNEL_FILE of=$OUT_FILENAME bs=1K seek=1088 conv=notrunc
mkdir rootfs
tar xf $ROOTFS_FILE -C ./rootfs
cp -r $KERNEL_MODULES_DIR rootfs/usr/
cp -r $SPEC_FILE rootfs/
# add some custom modify
#for f in $SCRIPTES; do
# ROOTFS_PATH=./rootfs bash "$f" -H
#done
fakeroot mkfs.jffs2 -s 0x100 -e 0x10000 --pad=0xAF0000 -r rootfs -o rootfs.img -D rootfs
fakeroot mkfs.jffs2 -s 0x100 -e 0x10000 --pad=0x400000 -o jffs2.img -D overlay
dd if=rootfs.img of=$OUT_FILENAME bs=1K seek=5184 conv=notrunc
dd if=jffs2.img of=$OUT_FILENAME bs=1M seek=12 conv=notrunc
rm -rf rootfs rootfs.img jffs2.img
通過如上腳本，會在output的目錄下生成一個16MB大小的 flashimg.bin 文件
二、下載燒錄
讓設備進去燒錄模式後（參考之前的文章 荔枝派Nano燒錄 ），通過如下腳本將打包好的 flashimg.bin 燒錄到Lichee開發板裏面
#! /bin/bash
sunxi-fel -p spiflash-write 0 ./output/flashimg.bin
三、開機啓動
在此附上，我的開機打印信息及圖片
