rv1109 display

回答: 在rv1109项目中涉及到显示屏的兼容方式。在uboot阶段，我们选择具体的LCD屏幕，并根据该屏幕的初始化序列来初始化和显示logo。具体的LCD屏幕兼容方式可以查找相关资料和追溯代码以获取更多信息。在提供的引用中，可以看到选择的LCD型号为L071，而不是目前需要的1218-A101NL66-28K型号。这可能是由于选错了LCD型号或配置的问题导致的。建议查阅相关资料和代码以确认和调整正确的LCD型号和配置。<em>1</em><em>2</em><em>3</em>

rv1126 QT drm

RV1126是一款由Radeon Technologies Group（RTG）设计的GPU架构，它主要用于嵌入式设备和低功耗系统，比如早期的Linux平板电脑和电视盒子。QEMU-DRI（Quantum Emulator Display Infrastructure）是一种虚拟显示驱动框架，而DRI（Direct Rendering Infrastructure）则是一个让用户空间应用程序直接访问图形硬件的库。

QT DRM（Qt Dynamic Resource Manager）是基于Qt库的动态资源管理器，用于管理和控制底层的显示设备，包括像RV1126这样的GPU，通过DRI机制。当你在Qt环境中运行应用时，QT DRM可以简化图形界面元素对GPU操作的管理，使得开发者无需深入了解底层细节就能编写跨平台的图形密集型应用。

这个错误通常是由于模板中使用了未定义的变量引起的。在这种情况下，错误发生在`{{ data|tojson|safe }}`这一行，说明`data`变量没有正确传递给模板。

请确保在调用`render_template`函数时，将`data`变量作为参数传递给模板。你可以尝试将`data`变量传递给模板的方式更改为以下代码：

@app.route('/')
def display_yaml():
    with open('your_file.yml', 'r') as file:
        data = file.read()
    highlighted_data = highlight(data, YamlLexer(), HtmlFormatter())
    css = HtmlFormatter().get_style_defs('.highlight')
    return render_template('index.html', data=data, highlighted_data=highlighted_data, css=css)

然后，在`index.html`模板文件中，你需要将`data`变量传递给JavaScript部分，可以将以下代码添加到JavaScript部分：

<script>
    var originalData = {{ data|tojson|safe }};
    // ...
</script>

这样，`originalData`变量就能正确地接收来自Python代码的数据。

请确保保存并重新运行你的应用，并刷新浏览器查看结果。如果问题仍然存在，请提供完整的错误堆栈信息以供参考。
