Linux or WSL
|
|||
|
|
================================
|
|||
|
|
|
|||
|
|
本节主要介绍如何在 Linux 或者 WSL 下使用 **命令行** 进行开发。Windows 下如何安装 WSL 请自行百度。
|
|||
|
|
|
|||
|
|
安装
|
|||
|
|
-----------------
|
|||
|
|
|
|||
|
|
安装前需要下载好 git 工具。
|
|||
|
|
|
|||
|
|
.. code-block:: bash
|
|||
|
|
:linenos:
|
|||
|
|
:emphasize-lines: 1
|
|||
|
|
|
|||
|
|
$ cd ~
|
|||
|
|
$ sudo apt install git
|
|||
|
|
|
|||
|
|
安装 make
|
|||
|
|
^^^^^^^^^^^^^^^^^^^^^^^^
|
|||
|
|
|
|||
|
|
.. code-block:: bash
|
|||
|
|
:linenos:
|
|||
|
|
:emphasize-lines: 1
|
|||
|
|
|
|||
|
|
$ cd ~
|
|||
|
|
$ sudo apt install make
|
|||
|
|
|
|||
|
|
安装 RISC-V 工具链
|
|||
|
|
^^^^^^^^^^^^^^^^^^^^^^^^
|
|||
|
|
|
|||
|
|
.. code-block:: bash
|
|||
|
|
:linenos:
|
|||
|
|
:emphasize-lines: 4-5
|
|||
|
|
|
|||
|
|
$ cd ~
|
|||
|
|
$ git clone git@gitee.com:bouffalolab/toolchain_gcc_t-head_linux.git
|
|||
|
|
$ sudo cp -rf toolchain_gcc_t-head_linux/ /usr/bin
|
|||
|
|
$ echo "export PATH=\"$PATH:/usr/bin/toolchain_gcc_t-head_linux/bin\"" >> ~/.bashrc
|
|||
|
|
$ source ~/.bashrc
|
|||
|
|
|
|||
|
|
安装检查
|
|||
|
|
-------------
|
|||
|
|
|
|||
|
|
完成上述两步以后，需要检查是否真的安装成功。打开 linux 终端。输入下列命令：
|
|||
|
|
|
|||
|
|
.. code-block:: bash
|
|||
|
|
:linenos:
|
|||
|
|
|
|||
|
|
$ make -v
|
|||
|
|
|
|||
|
|
此时应该显示如下内容表示安装成功：
|
|||
|
|
|
|||
|
|
.. code-block:: bash
|
|||
|
|
:linenos:
|
|||
|
|
|
|||

在 linux 中，有严格的权限限制，通常一个用户对应一个权限，所以如果提示下面信息，表示需要设置 cmake 权限。
|
|||
|

|
|
.. figure:: img/cmake_error.png
|
|||
|
|
:align: center
|
|||
|
|
|
|||
|
|
进入 sdk 根目录，输入:
|
|||
|
|
|
|||
|
|
.. code-block:: bash
|
|||
|
|
:linenos:
|
|||
|
|
|
|||
|
|
$ sudo chmod +x tools/cmake/bin/cmake
|
|||
|
|
|
|||
|
|
编译
|
|||
|
|
-------------
|
|||
|
|
|
|||
|
|
进入 **examples** ,选择你想要编译的 case，且该 case 下必须有 **main.c** 文件。生成的 bin 文件会输出到 `build/build_out` 目录下。
|
|||
|
|
|
|||
|
|
.. code-block:: bash
|
|||
|
|
:linenos:
|
|||
|
|
|
|||
|
|
$ cd .\examples\helloworld\
|
|||
|
|
$ make CHIP=chip_name BOARD=board_name ## chip_name 为芯片型号，可以填写 bl702、bl616、bl808、bl606p, board_name 为开发板名称，详见 bsp/board 目录
|
|||
|
|
|
|||
|
|
.. note :: 如果使用 BL808 或者 BL606P，需要在上面基础上添加 CPU_ID=id ,id 可以为 m0 或者 d0
