嵌入式ARM64 使用buildroot构建最小系统
平台：orangepi4 rockchip rk3399 LPDDR4 4G eMMC 16G
系统：ubuntu 20.04
buildroot是Linux平台上一个构建嵌入式Linux系统的框架，整个Buildroot是由Makefile脚本和Kconfig配置文件构成的。你可以和编译Linux内核一样，通过buildroot配置，menuconfig修改，编译出一个完整的可以直接烧写到机器上运行的Linux系统软件(包含boot、kernel、rootfs以及rootfs中的各种库和应用程序。
通常我们构建一个系统先移植uboot，然后移植linux内核，然后通过busybox再去构建根文件系统，这样做的步骤比较繁琐，每一个操作不好可能都会导致系统起不来的情况，通过buildroot来做的话极大地方便了系统的构建过程。
下载源码：
进入Buildroot - Making Embedded Linux Easy下载最新工程
选择最新版本：
解压源码：
tar zxvf buildroot-2021.11.tar.gz 进入源码目录查看一下configs目录下的配置文件，我使用的是orangepi4开发板，所以看一下有没有orangepi的配置文件：
可以看到有一个关于rk3399的配置是orangepi_rk3399_defconfig，但是这个配置不一定能够直接使用。只要按照合适的配置，buildroot会自动生成三种文件：uboot、kernel和rootfs，系统能够运行起来要保证uboot能够跑起来，因为rk3399可以支持三种内存：ddr3 lpddr3 lpddr4，要查看板子使用的是哪一个内存使用对应的uboot才能是系统能够运行起来。具体的选择可以参考我之前的文章uboot移植
配置：
vi configs/orangepi_rk3399_defconfig
可以看到uboot使用的配置是orangepi-rk3399，我将它替换成khadas-edge-rk3399然后执行
make orangepi_rk3399_defconfig
make menuconfig
Filesystem images--->
将exact size调整位150M
make -j8编译：
第一次编译时间比较慢，因为要下载一些代码编译器等等，
编译成功后会在output/image目录下生成镜像文件：
sdcard.img文件生成：
sdcard.img是用于在sd开启动的文件，可以使用瑞芯微的烧录工具写入，通过./output/build/host-genimage-14/genimage工具生成，查看board/orangepi/orangepi-rk3399/genimage.cfg文件：
image boot.vfat {
vfat {
files = {
"Image",
"rk3399-orangepi.dtb",
"extlinux"
}
}
size = 64M
}
image sdcard.img {
hdimage {
gpt = true
}
partition loader1 {
image = "idbloader.img"
offset = 32K
}
partition loader2 {
image = "u-boot.itb"
offset = 8M
}
partition boot {
partition-type = 0xC
bootable = "true"
image = "boot.vfat"
offset = 16M
}
partition rootfs {
partition-type = 0x83
image = "rootfs.ext4"
}
}这个文件会在support/scripts/genimage.sh脚本中使用，用于生成sdcard.img文件
烧录验证：
通过rkdevelop工具需要使用的文件是 idbloader.img u-boot.itb boot.vfat rootfs.ext2
使用以下命令烧录：
sudo rkdeveloptool db rk3399_loader_v1.25.126.bin
sudo rkdeveloptool wl 0x40 idbloader.img
sudo rkdeveloptool wl 0x4000 u-boot.itb
sudo rkdeveloptool wl 0x8000 boot.vfat
sudo rkdeveloptool wl 0x28000 rootfs.ext2
sudo rkdeveloptool rd要注意的是需要从mmc的第64扇区开始烧录，如果不小心把mmc的前面64个扇区的数据擦除掉了会导致uboot找不到内核地址从而无法引导内核，我查看了一下前面的扇区部分应该是有一个mbr的分区文件，实际上使用的是GPT的模式，应用的是第二个扇区，如果删掉就导致操作系统引导不正常，我在这里截取了sdcard.img的前部分的数据(只需要三个扇区)保存成一个文件，把这个数据烧入0x00的地址就可以了。
