OpenHarmony龙芯1C300B

介绍

OpenHarmony是由开放原子开源基金会(OpenAtom Foundation)孵化及运营的开源项目,目标是面向全场景、全连接、全智能时代,搭建一个智能终端设备操作系统的框架和平台,促进万物互联产业的繁荣发展。

OpenHarmony通过组件化和组件弹性化等设计方法,做到硬件资源的可大可小,在多种终端设备间,按需弹性部署。目前OpenHarmony最新的3.0代码已支持ARM、RISC-V、x86等各种CPU。但是目前OpenHarmony轻量系统还不支持MIPS架构的芯片,更不支持龙芯。

慧睿思通经过公司的努力,成功地将OpenHarmny移植到龙芯1c300处理器上,实现了国内第一家成功移植OpenHarmny轻量系统到龙芯、MIPS架构芯片的公司。

该代码开源,使用过程中有问题请留言或者联系我司:13512779286 饶经理 或者 13510979604 连志安

龙芯1C300芯片介绍

1C300是龙芯基于 GS232 处理器核的高性价比单芯片系统,内置浮点处理单元,支持多种类型内存,支持大容量 MLC 闪存芯片,可应用于工控、物联网等领域。

OpenHarmony版本说明

本仓库是基于OpenHarmony 3.0版本移植,通过裁剪,去掉不必要的组件,精简版本。 1c300裸机库基于勤为本的OpenLoongsonLib1c,感谢!

安装教程

  1. 下载交叉编译工具链 龙芯1C300编译器用来编译鸿蒙系统 龙芯1C库可以在Linux下与Windows下使用 MIPS.com 提供的 CodeScape MTI Bare Metal Toolchain 进行交叉编译 注意,请选择“MTI Bare Metal Toolchain”下的

MIPS官网的交叉编译工具链下载地址

下载后把交叉编译添加到自己的环境变量中去

  1. OpenHarmony开发环境 按照OpenHarmony官方提供的环境搭建,配置号gn、hb等环境,可以参考: 获取源码及Ubuntu编译环境准备

  2. 开始编译 hb set 选择ls1c300b_hrst 执行 hb build -f 看到如下提示说明编译通过: [OHOS INFO] ls1c300b_hrst build success 生成的烧录固件位于文件夹:out\ls1c300b_hrst\ls1c300b_hrst 固件:ls1c300b_hrst_ninjia.elf

  3. 烧录 配置好tftp,进入PMON,执行 load tftp://192.168.1.100/ls1c300b_hrst_ninjia.elf 下载完固件后,输入 g 开始执行。

  4. 查看现象 查看串口打印,如下:

entering kernel init...

查看LED灯,可以看到1秒闪1次。

使用说明

前期已经完成了轻量内核移植,多任务、中断、systick都没问题。 近期网卡和FPU功能已实现并开源,还有一些驱动适配中,也欢迎感兴趣的朋友一起加入到慧睿思通开源社区,共同维护、更新该开源仓库。可以添加13512779286(饶)参与共建。
