buildroot上游已经支持了D1 Nezha开发板，我为Lichee RV Dock做了如下适配开发：
A.uboot、opensbi使用了上游linux-sunxi社区的d1-wip分支，参见https://linux-sunxi.org/Allwinner_Nezha
B.linux kernel使用了上周日（2022年1月9日）release的linux-5.16 + linux-sunxi社区的d1-wip分 支合并而成
C.为Lichee RV CM和其Dock添加了dts文件
D.buildroot添加了Lichee RV的board/相应目录和configs/目录下相应的defconfig文件
这样做的好处是，紧跟上游，代码清晰，关键软件部件几乎最新。
0.host上安装用于buildroot的必要软件包
此过程略，可自行搜索解决
1.获取代码：
git clone https://gitee.com/xhackerustc/buildroot.git -b d1-wip2.用buildroot编译用于licheepi rv的img：
cd buildroot
make licheepi_rv_defconfig
make menuconfig //上游buildroot默认uclibc且最小化编译，riscv平台俺建议用glibc，软件包方 面这一步选一些需要的软件包
make3.编译完成后在output/images/sdcard.img就是要烧入sdcard的img
sudo dd if=output/images/sdcard.img of=/dev/sdX目前sdcard，sdio、usb host、user按键、wdt都能工作。
注1：因使用的是mainline的linux内核，sipeed wiki中的RGB LED WS2812 进行花式点灯需要改下:
点红灯：
echo 88 > /sys/class/leds/rgb\:indicator/brightness;echo 255 0 0 > /sys/class/leds/rgb\:indicator/multi_intensity接着上面点绿灯：
echo 0 255 0 > /sys/class/leds/rgb\:indicator/multi_intensity点蓝灯以此类推。
注2：此系统镜像也适用于只有Lichee RV核心模块的用户，当然usb host、RGB LED肯定不能用的，所以最好启动后修改/boot/extlinux/extlinux.conf文件，把其中的:
devicetree /boot/sun20i-d1-licheepi-rv-dock.dtb换成
devicetree /boot/sun20i-d1-licheepi-rv.dtb这两dtb文件镜像都自带了
上电后串口log如下：从此log可以看到opensbi升级到了0.9版本，uboot升级到了uboot-2022.01-rc1, linuxe内核是最新的linux-5.16

此buildroot仓库也可以编译生成D1哪吒的镜像，这是完全利用主线中的支持了。只要把步骤中的
make licheepi_rv_defconfig换成
make nezha_defconfig我没哪吒开发板所以测试不了，理论上编译出的sdcard.img是能启动D1哪吒的。
如果想像Lichee RV Dock一样，用最新的opensbi, uboot, linux kernel，可按configs/licheepi_rv_defconfig中e设置定制这三者版本的地方改configs/nezha_defconfig文件
