【龙芯2K0300蜂鸟板试用】3 体验四大操作系统(Buildroot、Loongnix、Openharmony、OpenWRT)

总结

1 openwrt和buildroot的镜像烧录成功
2 openharmony烧录成功,启动卡住,测试失败
3 loongnix镜像结构与上面3种不同,测试失败

4 个人感觉,官方不是很重视这次试用,提出的问题,只是草草的回答一下,感觉过 过场,生态建设任重道远
5 我相信,2k0300是支持4种文件系统,但不相信官方提供的镜像,它们都在2k0300上做过测试

文档

查看《广东龙芯2K0300蜂鸟快速使用指南-V1.0.240725》的1.5TF卡使用方法,可以看到,可将镜像安装到TF卡,官方提供了2种方法,即windows环境和linux环境,由于windows环境还需要安装7Z和UltraISO,故本文使用linux环境的方法烧录根文件系统到TF卡上。

$ sudo umount /dev/sdX
$ gunzip gunzip -S .img rootfs.img
$ sudo dd if=rootfs of=/dev/sdX

查看网盘《04-文件系统》目录,官方提供了4种文件系统(Buildroot、Loongnix、Openharmony、OpenWRT),且都有二进制和源码,极大地方便用户的使用和体验,但由于没有LCD,或者本测体验有少许遗憾。

在更新前,查看原始的uboot环境变量(启动按下c进入uboot控制界面)

=> printenv bootargs

bootargs=console=ttyS0,115200 root=/dev/mmcblk0 rw noinitrd
init=/linuxrc rootfstype=ext4 rootwait

=> printenv mtdparts

mtdparts=spi0.0:924k(uboot),32k(uboot_env),4k(bdinfo),64k(dtb)

进入内核的信息:

Openwrt:

简介:

OpenWRT是一个高度模块化、高度自动化的嵌入式Linux系统, 广泛应用于路由器的嵌入式操作系统,也用于用于工控设备、电话、小型机器人、智能家居、路由器以及VOIP设备等。

龙芯中科编译的是2022.03,官方当前开发最新版为2023.05

定位到《04-文件系统\OpenWRT\二进制》目录,可以看到rootfs.img镜像

烧录:

2k0300$ sudo umount /dev/sdb1

2k0300$ cp /mnt/hgfs/share/openwrt-rootfs.img ./rootfs.img

2k0300$ gunzip -S .img rootfs.img

ll rootfs

Openharmony:

简介:

鸿蒙中经常提及的OpenHarmony与HarmonyOS以及Harmony OS NEXT,这4者到底是什么关系呢?通过下图应该可以更直观的理解

《摘自https://baijiahao.baidu.com/s?id=1789115231956982514&wfr=spider&for=pc

中科编译的是openharmony4.1,官方当前开发最新版为5.0-beta

https://www.openharmony.cn/mainPlay

https://gitee.com/openharmony/docs/tree/master/zh-cn/release-notes

定位到《04-文件系统\OpenHarmony\ok4.1》目录,可以看到rootfs.img镜像

烧录:

经测试,官方提供的镜像,烧录后不能正常启动,官方,网盘openharmony的文件系统有问题(20240723),官方让升级uboot:
首先:想不了和uboot有什么关系?也没有说明
其次:即使后面升级了uboot,问题仍然存在

Loongnix:

简介:

中科编译的是2021.02,官方当前开发最新版为2024.05(从2013年开始,每3月发布一次(2,5,8,11))

基于Debian 10 的衍生版本。当前最新debian是12.6

烧录:

dd

if=Loongnix-Embedded-20.1.rc2-loongarch64-DVD-1.iso of=/dev/sdb bs=10M

如果要打印进度可以另开一个窗口输入: while killall -USR1 dd;

do sleep 5; done

启动:

启动无反应,询问官方官方,能否出一个使用loongnix的说明,提供了视频源,感觉很复杂,就没有试

其实我想,loongix是基于debian的,按道理可以做成buildroot类似的镜像,感觉光盘提供的,类buioldroot的镜像

https://www.debian.org/

Buildroot

简介:

Buildroot是Linux平台上一个开源的嵌入式Linux系统自动构建框架,由Makefile脚本和Kconfig配置文件构成的。

https://buildroot.org/

https://gitlab.com/buildroot.org/buildroot/

龙芯中科编译的是2021.02,官方当前开发最新版为2024.05(从2013年开始,每3月发布一次(2,5,8,11))

定位到《04-文件系统\Buildroot\二进制》目录,可以看到rootfs.img镜像,在full子目录下, 同样存在一个rootfs.img,从readme中可知,full下的根文件系统比较全,比较大小可知,fulll下的也比较全

烧录:

2k0300$ sudo umount /dev/sdb1

2k0300$ cp /mnt/hgfs/share/openwrt-rootfs.img ./rootfs.img

2k0300$ gunzip -S .img rootfs.img

ll rootfs

-rwxrwxr-x 1 xboard xboard 256000000 8月 7 10:29 rootfs*

启动:

可以正常启动
