使用mainline中最新的buildroot编译生成Lichee RV Dock系统镜像

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-wip

2.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
make

3.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

Re: 使用mainline中最新的buildroot编译生成Lichee RV Dock系统镜像

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
