ARM Linux跑OpenWRT系统，

STM32跑FreeRTOS+LWIP

两者的硬件采用串口连接。



为了充分利用openwrt的网络功能，决定在stm32上lwip，底层跑基于串口的SLIP协议。



经过2周的调试，功能已完全调通。

在openwrt中ping stm32，效果如下：

每次编译软件包，都耗时很长，开发效率太低。

这里说一种比较高效的方法。

先编译出openwrt SDK，在sdk中编译调试自己的软件包，待调试好后，再放到系统软件包。



另外，为避免每次编译软件包去服务器下载，可以将软件包源码从一个地方拷贝过去。



就写这么多吧。相信你看了会明白的。

背景

JSON/XML不好吗？

好，再没有一种序列化方案能像JSON和XML一样流行，自由、方便，拥有强大的表达力和跨平台能力。是通用数据传输格式的默认首选。不过随着数据量的增加和性能要求的提升，这种自由与通用带来的性能问题也不容忽视。

JSON和XML使用字符串表示所有的数据，对于非字符数据来说，字面量表达.]]></description><category></category></item><item><title><![CDATA[overlayfs，workdir的作用]]></title><link>https://blog.youkuaiyun.com/ee230/article/details/107188321</link><guid>https://blog.youkuaiyun.com/ee230/article/details/107188321</guid><author>ee230</author><pubDate>Tue, 07 Jul 2020 19:21:32 +0800</pubDate><description><![CDATA[OverlayFS has aworkdiroption, beside two other directorieslowerdirandupperdir, which needs to be an empty directory.
