搭建开发环境

https://gitee.com/openharmony/device_soc_bestechnic/blob/master/README.md

系统要求

系统要求基于Cortex-m33的liteos_m内核操作系统,采用arm-none-eabi-gcc 10.3版本toolchain, 提供16MB内存和16MB flash,或者40MB内存和32MB flash系统配置。

OpenHarmony在基于bes2600w 的芯片的Multi-modal V200Z-R模组,依赖liteos_m内核,内核依赖 cortex-m33架构配置,编译依赖arm官方的arm-none-eabi-gcc 10.3版本 OpenHarmony需要按照官方文档介绍安装环境 https://gitee.com/openharmony/device_soc_bestechnic/blob/master/README.md ,然后编译出烧录包,按照文档介绍烧录。

工具要求

ubuntu 18.04编译,windows10系统烧录。

  1. Ubuntu18.04系统安装

    sudo apt-get install build-essential gcc g++ make zlib* libffi-dev e2fsprogs pkg-config flex bison perl bc openssl libssl-dev libelf-dev libc6-dev-amd64 binutils binutils-dev libdwarf-dev u-boot-tools mtd-utils gcc-arm-linux-gnueabi
  2. Ubuntu18.04安装python3和pip3

    python3 -m pip install --user ohos-build
  3. Ubuntu18.04 配置tooLchain arm-none-eabi-gcc:

    下载arm-none-eabi-gcc 编译工具 解压 gcc-arm-none-eabi-10.3-2021.10-x86_64-linux.tar.bz2 安装包至~/toolchain/路径下。

    mkdir -p ~/toolchain/
    tar -zxvf gcc-arm-none-eabi-10.3-2021.10-x86_64-linux.tar.bz2 -C ~/toolchain/

    设置环境变量。

    vim ~/.bashrc

    将以下命令拷贝到.bashrc文件的最后一行,保存并退出。

    export PATH=~/toolchain/gcc-arm-none-eabi-10.3-2021.10/bin:$PATH

    生效环境变量。

    source ~/.bashrc
  4. Win 10安装串口驱动CP2102usbqd
