为什么叫平头哥呢 <p>感谢大佬的分享，有关内容同步审核的问题，实在抱歉给您带来了不好的体验，我们这边也了解了整体的情况。首先您和其他开发者总结和分享的开发经验肯定是有价值的，我们已经就您反馈的问题作了讨论并优化了审核的流程。如果后续还有相关的意见和建议，欢迎您直接联系我。</p>
<p>我也很感兴趣你这个在自建的WEB服务器中实现空中升级功能，编译到RVB2601下载并运行，速度很快，感觉很爽啊，，，，先下载你的代码看看，不过应该比较复杂，到时有问题再来请教啊。。。</p>
<p>问题来了，下功的并不是源码，只是一些hex文件，那么我要如何动态加载呢？？？</p>

为什么叫平头哥呢
<p>因为平头哥是最无所畏惧的动物，吃毒蛇就像是吃辣条，被咬了睡一觉起来接着吃，还喜欢吃蜂密，还能干掉蜥蜴！</p>
<p> </p>
<p>别看他个子小，狮子老虎也拿它没办法！</p>
