<p>前言 本文记录STM32命令行开发环境在Ubuntu上的部署，用以替代Windows上的RT-Thread-studio。RT-Thread-studio同样是开源
|

软件，但目前似乎没有Nixos上的打包。</p>

<p>使用USB连接开发板和开发PC，并使用lsusb查看是否连接成功：</p>

<p>如果你和我一样使用 qemu ，需要在libvirt中使用Add_hardware添加usb设备。</p>

<h2 id="pkggong-ju">PKG工具</h2>
|

<p>由于该项目大量使用Python，所以需要PKG包支持。首先我们修改这个文件的交叉工具链部分：</p>

|
||
</span></code></pre>
|
||
<p>随后可以使用PKG初始化并安装两个必要的包：</p>
|
||
<pre data-lang="shell" style="background-color:#151515;color:#e8e8d3;" class="language-shell "><code class="language-shell" data-lang="shell"><span>pkgs --update
|
||
</span><span>pip install kconfiglib
|
||
</span><span>pip install scons
|
||
</span></code></pre>
|
||
<h2 id="bian-yi">编译</h2>
|
||
<p>在完成以上设置之后我们可以开始编译。STM32使用scons编译系统，同样是menuconfig命令：</p>
|
||
<pre data-lang="shell" style="background-color:#151515;color:#e8e8d3;" class="language-shell "><code class="language-shell" data-lang="shell"><span>scons --menuconfig
|
||
</span></code></pre>
|
||
<p>修改配置并保存退出后即可开始编译，$(nproc)代表使用全部CPU线程来编译：</p>
|
||
<pre data-lang="shell" style="background-color:#151515;color:#e8e8d3;" class="language-shell "><code class="language-shell" data-lang="shell"><span>scons -j$(nproc)
|
||
</span></code></pre>
|
||
<h2 id="shao-ru">烧入</h2>
|
||
<p>编译成功后你应该会看到有一个rtthread.bin在目录下，这就是我们编译出来的系统！</p>
|
||
<p>在烧入之前，我们可以备份一下原来的系统：</p>
|
||
<pre data-lang="shell" style="background-color:#151515;color:#e8e8d3;" class="language-shell "><code class="language-shell" data-lang="shell"><span>st-flash read firmware_backup.bin 0x08000000 0x100001
|
||
</span></code></pre>
|
||
<p>随后使用如下命令烧入系统：</p>
|
||
<pre data-lang="shell" style="background-color:#151515;color:#e8e8d3;" class="language-shell "><code class="language-shell" data-lang="shell"><span>st-flash write rtthread.bin 0x08000000
|
||
</span></code></pre>
|
||
<h2 id="chuan-kou">串口</h2>
|
||
<p>除了USB之外我们还可以使用串口连接：</p>
|
||
<pre data-lang="shell" style="background-color:#151515;color:#e8e8d3;" class="language-shell "><code class="language-shell" data-lang="shell"><span>sudo apt install picocom
|
||
</span><span>picocom -b 115200 /dev/ttyACM0
|
||
</span><span>version
|
||
</span></code></pre>
|
||
<p>可以使用<code>ctrl + A 然后 ctrl + x</code>退出。</p>
|
||
<h2 id="shi-yong-cmake">使用Cmake</h2>
|
||
<p>通过官方文档可以得知除了scons外还可以使用Cmake来编译.</p>
|
||
<p>首先找到编译器的路径，并export：</p>
|
||
<pre data-lang="shell" style="background-color:#151515;color:#e8e8d3;" class="language-shell "><code class="language-shell" data-lang="shell"><span>❯ which arm-none-eabi-gcc
|
||
</span><span>/nix/store/v9p5md3d4aaqwc9i9hlaxkl7nawd9vrc-gcc-arm-embedded-14.3.rel1/bin/arm-none-eabi-gcc
|
||
</span><span>export RTT_EXEC_PATH=/nix/store/v9p5md3d4aaqwc9i9hlaxkl7nawd9vrc-gcc-arm-embedded-14.3.rel1/bin
|
||
</span><span>export RTT_CC=gcc
|
||
</span></code></pre>
|
||
<p>随后使用指令<code>scons --target=cmake</code>：</p>
|
||
<pre data-lang="shell" style="background-color:#151515;color:#e8e8d3;" class="language-shell "><code class="language-shell" data-lang="shell"><span>❯ scons --target=cmake
